Just as the Mouth triplets are about to finish their attack on Iron Michael, Guevaru rolls in and instigates a fight.

Guevaru refuses to believe that Biscuit Oliva, the most notorious inmate in the prison, is comfortably serving his sentence in the company of his lover.

The match between Guevaru and Oliva begins, and the rules are simple: They both hold onto the same piece of cloth and the first one to let go loses.

Guevaru is fighting for the people of his impoverished homeland, and he won’t go down so easily. Later, Oliva makes a discovery.

Oliva inadvertently kicks off a major incident when he enters Baki’s solitary confinement cell to challenge him to a fight in two weeks' time.

Baki learns the hard way that he might not be ready to fight the man known as “Mr. Unchained” — Oliva’s power and technique are on another level.

To train for his eventual battle against his father, Baki spars against an imaginary giant praying mantis he’s created in his mind.

With just a few weeks left on his sentence, Iron Michael is attacked by triplet hit men hired to make sure the ex-boxing champ never fights again.

Their battle has exceeded all expectations; and now, the family feud between the most powerful being in the world and his son reaches its conclusion.

The moment comes when Pickle recognizes Katsumi as his prey; Katsumi responds by quickly unleashing his new and improved Mach Fist move.

Yujiro uses his secret, highly effective "dress" move, grabbing Baki and spinning him around with such speed, his son begins to lose consciousness.

It's a past-versus-present battle when Pickle, a powerful prehistoric human, fights a man who has ingested the most advanced performance enhancing drugs.

Using an ancient battlefield move, Baki is finally able to subdue Yujiro in what should be an inescapable move. But then, Baki notices his father's hand.

The world is shaken by news of a man taking down a monstrous elephant with his bare hands. Back in Japan, Baki is confronted by a knife-wielding child.

Captain Strydum pays Baki a visit and gives him some shocking news; scientists have discovered a human preserved in a salt slab from the Jurassic era.

Baki cooks some food and sets his table; and sure enough, his father arrives and sits down. But this isn’t going to be a normal family meal.

Their nice meal at a fancy hotel turns violent when Baki asks Yujiro a personal question, setting off a sky high scuffle for the ages.

As a growing crowd looks on, the father-son battle continues. Baki puts his father on the offensive with a triceratops attack.

Pickle, who's used to devouring dinosaurs, struggles to find anything to eat in modern day Japan. Hoping to fight him, Retsu offers himself up as prey.

Baki counters his father's attacks by visualizing a cockroach. Meanwhile, word of the epic battle starts to spread and a huge crowd begins to gather.

Soon after the prehistoric human arrives in Tokyo, the fiercest underground fighters in the country attempt to take him on.

As riveted spectators look on, Katsumi Orochi sacrifices everything to his supersonic attacks, and yet Pickle continues to get back on his feet.

Retsu's first boxing match in America is announced, and it's against former world champion Andrei Valev. Meanwhile, Baki gets a premonition.

Baki enters Pickle’s enclosure and settles in; breathing the same air, eating the same flesh and living as the prehistoric man does.

Having recognized that the man he's now facing is stronger than any opponent he's ever faced, Pickle morphs into his true, all-powerful form.
