A primitive form of man found perfectly preserved in a saline rock formation (hence he is 'pickled') this giant humanoid supposed lived originally in the Jurassic/Cretaceous era. He is revived from his long suspended animation in Baki 10.5, and is sent to Japan by Strydum after he defeats entire army battalions and even a high-tech exo-skeletal powersuit sent against him. Pickle does not resemble any form of primitive man (Neanderthal or Cro-Magnon) or even modern humans, standing taller than Jack Hammer and possessing a level of muscular development equivalent to Oliva. He possesses upper and lower exaggerated canines, giving him a 'fanged' appearance, and his nails resemble claws. His muscles are so developed and powerful that he withstands three 9 mm. shots to the stomach at point blank range, none of which penetrate his abs, and indeed he believes the man who shot him to be engaging in some sort of rough-house 'game'. He hunted, killed and ate T-Rexes without the use of weapons in his prehistoric life, and is one of the most blatantly superhuman characters in the entire manga.
He has never been heard to speak intelligibly so far in the manga. His strength is shown in various occasions, being capable of withstanding a strength test with Yujiro himself, resisting a charge from Hanayama, sending Baki flying through the Korakuen arena with a single kick, chopping a leg from Retsu Kaiou after beating him, and enduring Katsumi Orochi's attacks and taking his right arm as a gift. When fighting Jack Hammer he lost his left ear to a bite attack after ripping off the flesh from Jack's jaw. He goes mad after this and beats Jack senseless. In Baki's battle against Pickle, Baki's adaption of dinosaur-like stances has led Pickle into believing that he's as dangerous as the combined-form of all the dinosaurs he's ever faced.Source: Wikipedia.
