Crank, Bolt

ボルト・クランク

Bolt Crank is the protagonist of the "Eat-Man" manga and anime series. He has also made guest appearances in other works by Akihito Yoshitomi, namely "Ray" and "24-ku no Hanako-san".
He is the world's top explorer/adventurer. In the manga, explorers are a type of mercenary; although mercenaries take on any kind of job, explorers are employees with principles. Bolt's past remained a mystery throughout the series, though some stories provided clues about it, including through characters appearing in various episodes. The end of the manga series revealed much about who and what Bolt is, but his exact identity still remains a mystery.
Bolt possesses a bizarre power: the ability to eat anything inorganic and later recreate it (even repairing the ingested item) from any part of his body. The item usually emerges from his arms and hands, but can sometimes be created in other body areas, such as his head, chest, or legs. The manga implied that inside Bolt's body is actually a void of space. Objects he has consumed float around in a seemingly endless space. Bolt also never ages, and the end of the manga series revealed that he is biologically immortal (he does not age but can be hurt and/or killed).
A man of few words, Bolt does not show his feelings and always keeps a cool head. However, his cynical personality and his "always get the job done" attitude can make him seem like a very cold and dark character, but in the end, he always finds a way to do the right thing. He never appears to look back on the past or regret it in any way.
Bolt says he has a very strict diet, unlike any human, and is only known to consume metals and gasoline, though he sometimes also likes to drink wine. His favorite "foods" are screws, nuts, gasoline, and gunpowder.
In the first anime adaptation of "Eat-Man", the Bolt Crank we follow is not the same as the one in the manga or the second anime adaptation; he is a variant from another reality who does not show much enthusiasm for being an explorer/adventurer, often considering abandoning the profession to try and live a normal life. In the first anime, Bolt is haunted by a ghost airship known as "LAVION," which, even after being destroyed years ago, continues to fly through the skies, following him wherever he goes.
