The preliminary rankings for top Medafighters off Japan is out. Ikki is #3, Koji is #2, and Space Medafighter X is #1. Ikki starts showing off for the cameras and Samantha (Leader of the Screws) claims that she taught Ikki all he knows. Ikki then challenges Samantha to a robattle and rather than actually FIGHTING, he orders Metabee to use the MedaForce for another one-shot kill. Obviously, he loses: Metabee can't just use the Medaforce whenever he wants. Then Ikki is out by the stream and is challeged by Mr. Dragon who ""traveled far"" to RoBattle Ikki for the #3 spot. Mr. Dragon uses Spitfire but loses because Spitfire touches water. Note: As said by Mr. Referee medafighters can only increase their ranking by winning first-time robattles, GREATLY disappointing Samantha, who was trying to cheat by beating Spyke and Cyandog.

In Ikki's neighborhood, a cart from Osaka that sells fried octopus balls sets up shop. Despite their good taste, Ikki voices his discontent, since he is a connoisseur of fried octopus balls. Natalie was upset and stayed up all night trying to perfect her recipe. The next day, she was enjoying a good crowd around her cart and again Ikki stopped by to taste her product. Unfortunately, he was once again not satisfied by the taste. Giving Natalie Ikki's attention and valuable advice, Natalie does not get upset, but instead falls in love with Ikki. Natalie is greatly troubled when she finds out that Ikki is ranked third in the nation of all Medafighters. Natalie must decide between her affection for Ikki, and her desire to eliminate him from the competition so she can compete in the World Robattle Tournament and promote her father's fried octopus ball recipe. Very distracted by the smell of fried octopus balls, Ikki almost loses a Robattle to the Clam-Type Octoclam Medabot.

A snowstorm causes the school to be closed. Ikki and Erika are having a snowball fight with the Screws, and don't hear the no-school announcement. Still thinking they have school, Ikki, Erika, and the Screws all report to school and are surprised to find no one there. They decide to go home after a while, but they meet up with Tom and Snowbro, who supposedly are the #1 team in Japan. Metabee gets frozen with Snobro's special attack, but quicky thaws and gets back into action.

Spyke and Cyandog argue with each other and the two end up going their separate ways, with Cyandog deciding to join The Rockers. Determined not to show how much he misses his old Medabot, Spyke buys a Krosserdog Medabot but it just isn't the same without his old buddy. The two eventually reunite, but the turn of events leaves Cyandog's medal in Krosserdog's body, giving Spyke his old friend in a new way.

Spyke and Krosserdog are practicing when they see a big medabot. Hmm. Ikki is telling Dr. Aki about how he and Metabee were attacked by these mystery medabots. Dr. Aki says that other companies make Medabots now and it was probably one of their work. Ikki and Erika go exploring when they find Spyke and Krosserdog attacked. They claim that a big Medabot attacked them. Then Samantha blaims Ikki for attacking Peppercat. And Samantha admits that she takes ballet lessions. Yes, you resd right, ballet lessons. Anyway, many other Medafighters blaim Ikki and Metabee for attacking their Medabots. Ikki and Metabee manage to escape. They come to a conclusion that Metabee has been cloned. Now we find Koji kiting a sock. Yes, you read right again. Koji is nitting a sock. He says it's because nobody has chalenged him to a Ro-Battle. He and Sumilidon decide to go find some opponents. Then they meet Rintaro who really fancies Sumilidon.

As the story returns to where it left off last episode, we see the mysterious medabot reveal itself. It is a KBT type, Arcbeetle and it belongs to the number 1 Medafighter in Japan, Space Medafighter X (who looks a lot like the Phantom Renegade, who looks a lot like Henry) Space Medafighter X challenges Shrimpy Lipowitz and wins easily, winning back Ikki's medal. As he returns the medal, he lectures Ikki that he should never fight for medals, only medaparts. Ikki argues that he had no choice, but Space Medafighter X is gone. Later that day, Ikki discovers that he has dropped to fourth place in the Medabot rankings after losing to Shrimpy Lipowitz under his real name rather than as a member of the Rubber Robo Gang. This bums him out and he begins to sulk, but Rintaro drags him along to a Medabot Training Dojo. While Rintaro and Koji begin to train at the gym, Ikki continues to sulk. Erika and Karen discover that the dojo is really a front for the Rubber Robo Gang's latest plan but it is

Space Medabotter X goes to share information with Koji on how he can compete against Ikki and Metabee's Rare Medal. Although Koji can't invoke the Medaforce, there are ways to combat it. Still ranked at only number four, Ikki desperately looks for a new opponent to Robattle in order to regain his top three ranking. Squidguts and Samurai-Type Medabot Gobanko spread the word that they are looking for a Robattle with a formidable opponent. They wait for Ikki and Metabee on top of a pedestrian bridge. When doing battle against Squidguts, Metabee is again able to summon the power of the Medaforce to defeat his opponent.

After seeing Ikki and Metabee use the Medaforce, Koji decides to train harder than ever to be prepared in case he ever has to face it. Space Medafighter X shows up to help him learn a special technique, the ""Shadow Sword"", which will help him to do this. Ikki and the gang (Karen, Erika and Rintaro) show up to watch Koji train, and Rintaro accuses Meda-X of being Henry. The others think he means Henry from the store, but he says that Meda-X is the Henry who won the International Robattle Tournament eight years ago and that the two Henrys are different (hmm). Meda-X denies this and leaves. Later, Meda-X warns Ikki that Koji has nearly mastered the Shadow Sword and that he should prepare a defence against the Medaforce being blocked. Ikki ignores him, but later discusses it with Metabee. Later, Ikki and Metabee challenge Koji and Sumilodon to a rematch. Metabee has dcided to wear Rokusho's cape in the hopes that his strength might rub-off onto him.

Ikki and Metabee have to decide what to do. Do they want to mae the rankings for the Medabots Ro-Battle Championships or does he want to save his mom. They both decide to save Ikki's mom who was kidnapped and willingly making soup for the Rubber Robos. When he gets there, Ikki Ro-Battles Gilgirl and gets another point toward his standings. Then he battles 2 more RRG members but it doesn't count toward his rankings cause he already battled them. Metabee uses the Medaforce to win and gets very tired out. When he was about to take his mom back, all the RRG unleashed their Medabots at Ikki and Metabee but Space Medafighter X saved Ikki and his mom. Outside in a safeplace, Ikki and Metabee said that they were just glad to get their mother back and that they didn't care about Ro-Battle Standings but when Space Medafighter X taunted them, Ikki and Metabee chalenged Space Medafighter X to a Ro-Batlle. Is Ikki nuts or what!

It's the day of the final standings for the World Robattle Tournaments and Ikki is STILL in fourth place. In fact, with only 20 minutes until the close of rankings, Metabee is exhausted and the only new Medafighter nearby is Space Medafighter X. Ikki, in a fit of rage, at the end of the last episode challenged Meda-X to a robattle. While his friends try to convince him not to, he is relentless. Karen offers that he robattles Rintaro, but Ikki refuses. He is determined to fight Meda-X and Arcbeetle. With help from his friends, Ikki powers up Metabee with extra parts. With Crosserdog's arm and Kantaroth's laser cannon Metabee has more fire power and Sumilodon's legs for extra speed, will Metabee be strong enough to defeat Arcbeetle. The battle rages and it seems like Metabee is out for the count, but in a stunning recovery, he looks like he is about to use the Medaforce when the Rubber Robo Gang attack Ikki in order to steal his Medawatch. Meda-X blocks the attack, but his mask is...

The Rubber Robo Gang swoops down and bot-naps Metabee. He is weak so he can't fight back. They take Metabee to their secret hideout in a helicopter. Since the rest of the gang left Seaslug, Gillgirl, Squidguts and Shrimplips behind so Ikki coaxed out of them the location of the RRG hideout. Then Ikki and his friends go to Miyama Ruins where Metabee is hidden. There, members of the Rubber Robo Gang try to take Metabee's medal out of him. When Ikki and Koji get to the Miyama Ruins, they find outdated medaparts and Medals. The Ruins are filled with Death Traps and Booby Traps and they cause the group to separate. The RRG flees. While looking for Metabee and the rest of their friends, Ikki, Samantha, and Koji find 3 Medabots with out any Medafighters. Summilidon and Peppercat fight them but are no match, but then Rokusho comes and saves the day.

Dr. Meta-Evil uses Metabee's medal to control every Medabot in the world! Brass starts to attack Erika and Karin and Kantaroth starts attacking Rintaro and his group. Then, amasingly, we find out that Dr. Meta Evil was once Dr. Hushi's assistant. Dr. Hushi found out the power of the rare medals and he wanted to distroy all his reaserch and findings but Dr. Meta-Evil stole the information to use it for evil. More suprises are in store when it's revealed that Dr. Meta Evil is part machine himself! Peppercat and Sumiliodn attack him but don't do much damage. Rokusho distracts the Evil Doctor as Ikki stes Metabee free. When he does that, the curse is broken.

Dr. Meta-Evil looks to be finished. But is he? a srtange cat puts a reare medal in to a HUGE Medabot and it takes Metabee, Rokusho, and ArchBeetle to fight him. Even when all 3 of them use the Medaforce, it doesn't seem to stop Giganko. Giganko goes into town destroying everything in sight. Not even the Police can stop this Medabot. Ikki realizes that Giganko is a Medabot too and he could be stopped if his Medal comes out. Ikki and Metabee fight bravely and Giganko's medal comes out! Then they realize that when they beat Seaslug in a Ro-Battle, it gave them enough points to advance to 3rd ranking. Ikki can still participate in the world Ro-Battle Championship.

As competitors from around the world gather for the start of the World Robattle Championships, Mr Referee is shocked to be informed of a new rule for the contest. As Ikki and Koji meet up, they worry that Space Medafighter X might not turn up for the competition and that they will be disqualified, however Ikki and Metabee have more important things to worry about when they immediately get off on the wrong foot with world champion Victor of Team Kenya. When Ikki learns that an exhibition match between Team Kenya and Team Japan will be held during the opening ceremonies, he and Metabee look forward to taking Victor on, until Space Medafighter X fails to turn up for the opening ceremony. As the teams are all introduced, Mr Referee reluctantly announces the new ruling for the championship, that the loser of each robattle must give up their medal to the winner. The stunned players take in the news as the exhibition match begins, but with Space Medafighter X still a no show, Team Japan is ab

After their near defeat in the exhibition match, Ikki and Koji are worried about how they will fare in the championship, especially as Space Medafighter X still hasn't turned up. While the two start arguing about who is going to be team leader, they rescue a little girl from the Caribbean team and let her watch them training. When the robattle begins later that day, Karen has to take MedaX's place yet again, but as the robattle begins they realise that the girl they helped was actually the daughter of Team Caribbean's leader. As the Caribbean rips through Team Japan, the three have to work together in order to defeat their opponents and make it through to the next round. With the three friends finally working together, Henry decides that it is time for the real Space Medafighter X to make his appearance, but how will the team fare against the rest of the opposition.

Ikki and Koji become suspicious when they learn that Tem France has won all of their matches by default because their opponents have failed to turn up. When Metabee's medal goes missing, the gang suspects that Team France have stolen it, but find that their opponents are able to dress up like other people, making them hard to catch. As the gang tries to recover their medals, Team France kidnaps Karin, so Samantha has to stand in as Space Medafighter X, but as the Robatlle prepares to begin, the real Space Medafighter X (a.k.a Phantom Renegade) has switched places with one of the members of Team France and so the team has to forfeit the match, meaning that Team Japan advances automatically.

Samantha is training for both the comming robattle AND a ballet recital. To make matters worse they're sceduled on the same day. Samantha really wants to impress her mom, but she doesn't want to disapoint her team.

As Team Japan prepares for their fourth round match against Team Sweden, Ikki, Koji and Sloane (Space Medafighter X) are all infatuated by the three beautiful girls that make up the team. As Spyke and the girls try to snap them out of it, it seems like there is nothing they can do to get the guys to practice. When the match begins, it seems like Team Sweden is in for an easy victory, until the Phantom Renegade reveals that Team Sweden are actually male Rubberrobo Gang members dressed up like beautiful women. Furious that they have been tricked so easily, Metabee wipes out his opponents using the Medaforce, taking Team Japan through to the final eight.

Ikki, Koji and Spyke (Space Medafighter X) find themselves up against Team Egypt in the quarter finals, but when the leader of the team, Patra, warns them that they can't win until they identify their weakest link, Koji is sure that she means Spyke because he has the weakest Medabot. As the three begin training, Spyke tries his hardest but Koji tells him to just stay out of the way and leave him and Ikki to do the robattling. However as the robattle begins and Team Egypt takes an early lead, Patra informs Koji that he is the weakest member of the team. As a stunned Koji tries to take in what his opponent has told him, it's up to Spyke to save the day and stop Team Egypt from winning the robattle. Meanwhile, Ikki and Rintaro learn about the Ten Days of Darkness that occurred during the WRC eight years ago and Ikki is stunned to learn that the competitor who caused the incident (the same Henry who Rintaro is obsessed with) caused the Ten Days while using a Metabee.

Stunned by the news that Hikaru Agata and Metabee caused the Ten Days of Darkness at the WRC eight years ago, Ikki and the others head off to find Henry, certain that he knows more than he is letting on about the incident. On the way, Ikki explains that Henry suggested the name Metabee, and he thinks that Henry and Hikaru may be one and the same. While the gang have no luck finding Henry, Koji is in shock after seeing how he almost let the team down against Patra and Team Egypt. As a disheartened Koji wonders how he can help the team without being able to use the Medaforce, a confrontation between Joe, the leader of Team USA, and Space Medafighter X results in the real Medafighter agreeing to fight in the semi-finals. As the robattle begins, Koji is unable to fight and Team Japan looks set for an early defeat, but as Arcbeetle seemingly destroys both Team USA's Medabots and Metabee as well, Sumilodon jumps in, rescuing his team mate. Determined not to lose, Joe reveals his secret move,

Team Japan's day off goes in unsuspected ways when Dr Aki insists that he check out why Sumilodon was able to use the Medaforce. Leaving Koji behind, Ikki and Erika head off in search of Team Iceland to check out the competition, but Erika soon falls in love with team leader Belmont. When Belmont falls ill saving Erika, she feels guilty that he might not be able to compete and pleads with Victor to postpone the match but he refuses. The match goes on as planned and although Belmont fights valiantly, Warbandit is too powerful and Team kenya wins the second place in the finals, taking Orkamar's medal as their prize. While Belmont mourns the loss, Ikki vows to win back the medal by defeating Victor in the finals, however Brass tries to explain that Warbandit told her that Victor does not want to take the medals, but is doing it for another reason.

As Team Iceland recovers from their defeat, everyone is in shock as the board of directors for the World Medabot Corporation reveals themselves to be the Rubberrobo Gang. While Ikki tries to take in the news, Koji is pleased to hear that Sumilodon should be fine to battle in the finals, however things won't be easy against the World Champion, Victor. Seeing the Robos on television, Miss Caviar recognises Seaslug as the man she fell in love with and tries to talk to him, but when he ignores her she vows revenge, forcing Dr Aki and the Phantom Renegade to let her be Space Medafighter X in the final round. Meanwhile Rokusho learns tyhat Victor has been hired by the Rubberrobos and warns Ikki, who confronts Victor when Mrs Tenryou accidentally invites him home for dinner. During the meal, Victor tells Ikki more about the horrors of the Ten Days of Darkness, but even after hearing his warnings, Ikki is still determined to beat Victor and wim back Orkamar's medal for Belmont. As Team Japan p

As the finals of the WRC begin, Miss Caviar (as Space Medafighter X) heats things by making a special announcement to the head of the Medabot Corporation, Seaslug. If Team Japan wins the Cup, then Seaslug must quite the Rubberrobos, however if Team Kenya wins, Miss Caviar will join the Robos. As the robattle begins, both teams are on top form and it looks like it could be anyone's game. But as the two teams fight on, Medabots are destroyed one-by-one until only Metabee and Warbandit are left. A crushing blow from Warbandit almost destroys Metabee and in the process fries Ikki's medawatch. Certain that he has won, Victor prepares to leave the stage, but Metabee refuses to give up, summoning the Medaforce to eliminate his opponent. But when Warbandit also summons the Medaforce, the two blasts hit each other head on and the stadium is filled with light...

The violent combination of Metabee and Warbandit's Medaforce blasts shakes the whole stadium, as, far beneath the arena, Rokusho and the Phantom Renegade discover that the Rubberrobo Gang's hideout has been beneath the Medadome all along. They discover a massive resonating antenna, and the Phantom recognises the truth, racing to tell Doctor Aki while Rokusho takes on a team of Whitesords. Warbandit and Metabee, meanwhile, appear caught in a state of suspended animation, and, in a dream state, deep in the recess of his own mind, Metabee sees a world devastated by war. Victor and Ikki bring their Medabots around, but the strength of their robattle spirit is affect both their medals, and the medals of all the other Medabots around them - and the Phantom Renegade suddenly appears to explain why! The entire stadium is a gigantic resonance device, harnessing the energies of the rare medals and spreading it's effect to all the medals within.

Metabee finds himself in a paradise... a world of Medabots, but no humans, where a Medabot who is apparently Brass calls him ""Kyuumu."" Doctor Meta-Evil reveals that he thinks of himself as a Medabot, having cybernetically enhanced his body. Then, he delivers the ultimate revelation... Eons ago, the beings that we now know as Medabots were the rulers of the Earth. But they were obsessed with battle and war - to evolve and fight, they modified their bodies into robotic, metal, armored forms. But their war decimated both their race and the world, and so the survivors encoded their minds into small metallic hexagons - Medals - so that when the world was returned to life, they might live again, too. But when this race was returned to life, they were no longer what they had been - now they were Medabots. It is within his own memories of this past time that Metabee's mind now resides, as he and Rokusho's former self battle each other as generals of opposing armies.
