Outraged of his brother's death, Garer orders revenge to General Butto. Butto sallies forth out of Boot City, commanding enormous 70 divisions. In the meantime, King Racko of Ren sends his force to Nankyo, Thunder Jet's headquarters. All T.J. can do is to defend his line against Butto's fleets. In Nankyo, Sunluck goes to meet King Racko and manages to obtain a truce from Racko. T.J. defeats Butto's fleets with a new weapon called " Thundering Cannon."

Rogina reluctantly accepts Garer's request to subdue Thunder Jet. T.J. decides to fight her without the help of Sishin and other operation staff. Rogina assembles five great warriors called Five Tigers from their posts at the boundaries of Holy Empire. T.J. starts his battle against Rogina's fleet in the place called Sea of Seven suns. He has superiority at the beginning, but it is Rogina's strategy. When T.J.'s defensive line becomes less solid, Rogina's main force charges in at T.J.'s flagship, Kongo.

When Thunder Jet. comes back with Ashin to Boot City, Sishin prohibits T.J. from going out to battle any more. He fears to lose T.J. by an unexpected incident. In the meantime, King Racko wins battles one after another with his new battleship and swiftly marches on. T.J. orders Colin to gather information of this battleship. Cobin's fleet catches sight of the battleship in the meteor belt. Cobin is stunned of its gigantic size!

RACKO of REN KINGDOM vows revenge on ROGINA, the female General of Gojo, for the death of his father. QUEEN MASSINA sees an opportunity in this and talks RACKO into joining their forces so that Racko can fulfill his vows. Racko waits in hiding as Rogina's fleet approaches. He then unleashes his army on the unsuspecting fleet of Rogina And Racko heads straight to Rogina's flagship. He boards it with his men and a free for all battle breaks out. ROGINA is cornered and is about to go down in defeat when Thunder Jet comes for rescue in his flagship, KONGO. Now, Rogina's fleet is in general retreat. In order to rearguard her fleet, Rogina asks for a volunteer and T.J. steps up for the task. T.J. sets a trap for Racko and Rogina is able to slip out with her fleet. Racko vows to fight T.J. for another day.

One of the four Generals of Gojo Kingdom, FOMAY, spreads a rumor that Simone was involved in the rebellion. As the consequence, Simone is arrested by Reila. Fomay wanted to make certain that Simone and her heritage would not be used by Massina or Gen-Yee. Thunder Jet gets a wind of Simone's arrest and decides to rescue her. He knows she is innocent and he believes she does not deserve such a treatment. T.J. succeeds in rescuing her but, pursued by Reila's men, he gets into a tight spot, only to be saved by Gen-Yee. This rivalry between the two Generals, Fomay and Gen-Yee, becomes one of the causes that throws the cosmic conflict into further confusion.

Queen Massina of Kingdom of Ty learns the turmoil of Go-Jo and decides all-out attack. She takes direct diving attack to Boot City, the capital city by the suggestion of Leige, her first attendant. Meanwhile, in Nankyo, Thunder Jet, Sishin and Simone are talking about who will conquer the entire galaxy. Then, they receive a news that the first assault troop of Kingdom of Ty is heading for the capital city of Go-Jo.

Queen Massina sends a large fleet commanded by General Sion to Nankyo to secure her back. The fleet outnumbers Thunder Jet's fleet by 10! Our hero cunningly defeats Sion's fleet by a brilliant strategy of Sishin. In the meantime in Kingdom of Ren, King Racko is plotting to occupy Kingdom of Ty. It is a three-sided war between Kingdom of Go-Jo, Kingdom of Ty and Kingdom of Ren.

Thunder Jet declares to destroy Garer to his soldiers. Sishin tells him it is necessary to increase the military power as quickly as possible. Sunluck suggests to win a space pirate Colin and his son, Cobin, over T.J.'s side. They have not been actually defeated by any fleet before. Thunder Jet and Sunluck visit the pirate and demand allegiance to T.J.. Cobin gets outraged but Colin talks down him to support T.J. Adding the strong space pirates under his command, the power of T.J. increases tremendously.

Garer's brothers, Gasan and Gaten, tell Garer to demote Thunder Jet and his supporter, Rogina, out of fear of increasing power of T.J.. Garer trusts Rogina and turns down his brothers' idea. Gaten plots to assassinate T.J. and Rogina. He gives the post of General to T.J. and kill both jet and Rogina at the celebration party of Jet's promotion. Sishin knows Gaten's stratagem and ruins all his attempts. Rogina admires help and devotion of T.J.'s men. But, it will bring a new destiny to T.J. and Rogina.

Lan-Lan meets an orphan boy, Lin-Sock in town and asks Sunluck to hire him to do chores. This boy will be second strategic adviser to T.J. soon. In the castle, Thunder Jet wants to know why Rogina ever tries to destroy Garer. Sishin explains the way Rogina lives—She is destined to live with Kingdom Go-Jo and will perish when the kingdom falls. T.J. is shocked by the pitiless destiny of Rogina.

Garer becomes the emperor of the Great Go-Jo. Thunder Jet has something to settle before he starts war against Garer. It is Simone. T.J. loves her but she cannot forgive him for her father's killing. He tells her to kill him if she wants. Simone starts giving out how she feels finally. She is in love with him, too. Then she tells T.J. what her father wanted—the peace of entire galaxy. T.J. promises to realize the peace some day.

Thunder Jet sends a force to overthrow Garer, new emperor of Kingdom Go-Jo. The front fleet commanded by Cobin, the son of Colin the pirate, surround the first target, the great fortress of Gen-Bookan. The fortress has the gigantic cannon and It is too dangerous for Cobin's fleet to get closer. Emperor Garer orders his brother, Gasan, to destroy T.J. Sishin prepares a secret operation for the purpose of a short decisive battle. His idea is to plant the rocket engine on a huge meteor and clashes it to the fortress. His operation goes well and the fortress is destroyed. T.J. charges into Gasan's command ship and slashes him down.

Irritated by Thunder Jet's successive advance, Garer holds the meeting of military staff. Gaten has a dispute with an intelligent staff. Sishin, T.J.'s military strategist, tells Taskee and Munk to sneak into Boot City. Taskee makes up an incident showing Gaten is a traitor. The mission works beautifully and Garer puts Gaten in jail. Kingdom Go-Jo loses a good strategist.

Attacked by Rogina's main force, Thunder Jet has to retreat. Lin-Sock, second adviser of T.J., diverts a comet in collision course to a sun nearby. The sun is activated instantly and Rogina's battleships are sucked by the devastating energy storm. T.J. orders his battleship all-out attack and Rogina calls for decisive charge to her remaining ships. The fatal confrontation of two warriors is coming to an end in the burning sea of deep space.

Thunder Jet grinds his ship into the troop under Rogina's direct command and crashes it to her ship. Duel of T.J. and Rogina sparks and Rogina is wound badly. She praises T.J.'s braveheart and success and jumps into the sun, saying "Realize your dream at all risk!"

It is tremendous shock for Thunder Jet to destroy Rogina . Simone wants to console her and heads for T.J.'s ship. But, she is captured by a surveillance ship sent by Kingdom of Ren. Fortunately she is saved by Ashin, the brother of Sishin, who is disguised as a merchant. T.J. pulls himself together thanks to warm consolation of Simone and other friends.

Gen-Yee should have been assassinated by Garer, but he is still alive! He sallies forth with Kagan, his devoted follower on the ghost warship. Emperor Garer plans to attack T.J. on both sides with the remaining battleships of Five Tigers who fought under the command of Rogina. But, Gen-Yee appears and destroys all the ships of Five Tigers. T.J.'s strategist Sishin orders to concentrate all firing at Garer's flagship. Garer is forced to retreat after his ship has heavily damaged. Gen-Yee uses sorcery on Gaten, Garer's brother and revives him. What is he scheming?

Revived Gaten commands a fleet by himself and attacks Thunder Jet. He tries to destroy T.J. by a swift ambush but, in vain. Sishin's operation of "encircle and attack all side" smashes Gaten's fleet. T.J. chases Gaten to Sei-Oat City. T.J. marches on into the city and clashes with Garer himself. He corners Garer but fails to capture the emperor by desperate counterattack of Gaten. However, escaped Garer is killed by Gen-Yee soon after. T.J. wins the battle but he has no idea that his victory is brought by Gen-Yee.

The fleet of King Racko, Kingdom of Ren, cruises to Nankyo, insisting the truce between Ren and T.J. has expired. Racko seizes Nankyo quickly and Racko's counselor, Cosishoo plans to demands T.J. to surrender by taking Reila and Simone as hostage. Sishin knew this scheme and had already ordered Sunluck to lead the ladies out of the castle. With timely help of Taskee and Munk, Sunluck have the ladies to get out of Nankyo, but, he is caught by the posse.

Thunder Jet and his followers come back to Boot City, the capital of Planet Go-Jo. It seems that T.J.'s dream is coming closer. Kagan, Gen-Yee's trusted follower, plots T.J's assassination. Disguised as an old woman, Kagan hands a spelled dagger to hypnotized Simone. Her plan is perfectly set up. But, T.J. is saved by Banyou, a wandering warrior, at the nick of time. T.J. thanks his help. Banyou does no take T.J.'s appreciation. Instead, he challenge a fight with T.J. He wants to gain fame by defeating T.J. The fight becomes indecisive and Banyou disappears, saying he will come back.

Although defeated and thrown out of Nankyo by Thunder Jet's force, King Racko succeeded to capture Kingdom of Ty by a resourceful plan. Racko is now the ruler of all Southern Region of Galaxy and begins aggression toward Kingdom of Go-Jo. In the capital of Go-Jo, Sishin asks T.J. to stay in the castle as he is now the emperor. But, T.J. insists to fight in front. Meanwhile, Ashin, Sishin's brother, is captured by Banyou. T.J. sallies forth on his command ship, "Kongo." He defeats Banyou in a man-to-man fight with Banyou and rescues Ashin. But, it is a bitter victory for T.J. as Banyou once saved his life.

Colin challenges King Racko's new battleship, "Imperial tiger," with various tactics in order to get the datum. He is blasted by the front cannon of Racko's ship. Thunder Jet feels responsible in Colin's death and wants to go fighting King Racko. But, Cobin, Colin's son, opposes T.J.'s sortie and volunteers to command the attack force. Racko's fleet continues to destroy Go-Jo's troops. T.J. is frustrated of worsening situation and forces Sishin to agree his command at the front.

Thunder Jet arrives to take his new command but the waiting soldiers mistake him for a new recruit and provoke a fight. T.J. immediately displays his strength by beating up some of the men but they are too many. He is about to be overwhelmed when Mokack, the deputy commander of the 4077 intervenes. The manner Mokack handles the situation impresses T.J. but Mokack's opinion of T.J. is not likewise. And soon, an all-out assault on Ty Kingdom begins. Among those who watch the whole army march out is SIMONE who, more than ever, determined to avenge her father's death. 4077 Heavy Armor makes a steady advance and crosses the boundary between North and south. However, many questions remain in Mokack's mind, most of all, his doubt about T.J.'s ability to lead the soldiers and ship. He fears many of his men will be sent to a battle in vain. Then, the news of an approaching enemy fleet reaches T.J. he takes command.

The approaching enemy turns out to be group of hi-speed space frigates. Despite Mokack's concern, Thunder Jet orders an attack. As it turns out, it is a decoy. Though T.J. destroys many of the frigates, his fleet is broadside by swarming fleet of high speed attack boats during the engagement. The Heavy Armor sustains damages. Enraged, T.J. orders to go after the retreating boats. Fearing another trap, Mokack advises T.J. to hold the position but he is too stubborn. He finds the enemy base of the speed boats and demolishes it. However, just as Mokack has predicted, it too turns out to be a trap. While T.J. bombards the base, MASSINA pounces on the convoy of supply ships in the rear. T.J. is forced to turn around to rescue them. That is when the main force of Massina's fleet comes down on Thunder Jet with its full might. Now, his entire fleet is in danger of being decimated. Yet, T.J. remains cool. He is at his best when the ship is down. He turns the situation around and defeats the enemy. Thus a close mutual trust begins to bond the commander and his deputy, T.J. and Mokack. His men too finally come around to trust T.J.'s ability.

The combined force of Southern Territory is now on an all-out offensive. It forces Gojo's army into defensive operation and soon, it becomes a rout. Even Thunder Jet's flagship is badly damaged and he has to keep a low profile behind a Comet until repairs are being made. Then, T.J. spots the fleet of Massina's main force approaching. He mounts a surprise attack, a daring but a desperate assault. He heads straight to Massina's flagship to destroy Massina once and for all. But he faces deadly counter-attack by Massina's deputy, Hee-Lai, and is critically injured. Thus, MASSINA manages to slip away from his burning ship telling his younger brother to watch and learn from T.J., the true courage of a warrior. It seems now T.J.'s luck has finally run out. In a nick of time, Rogina's rescue team arrives and gets him out of the burning ship. After this battle, the cease fire is arranged between Gojo and the combined force of Southern Territory.
