Bakuzan

"You see Suiryu... I love torturing people weaker than me! That was my only reason for becoming stronger! Being free like this now is the best feeling!"

- Bakuzan revealing his true nature.

Bakuzan is a minor antagonist in the manga/anime series, One Punch Man, serving as one of the main antagonists in the Super Fight Arc.

He was a martial artist who practiced in the arts of the Dark Hell Assassination, known for using punishing techniques. He has fought in the Super Fight Tournament over the years to the point where he gained fame and earned himself the title as the Strongest Man in the History of Super Fight.

Personality
Bakuzan is infamously known for his barbaric nature when entering in martial arts. He gained his reputation whenever he performed his brutal techniques on his opponents, which usually result in one sided matches. He has a vastly different view on martial arts than from what one would normally view it as, believing that taking part in martial arts places your life on the line instead of being competition.

Bakuzan takes great pride of himself as he looks down upon those that are weaker than him. Despite this, he holds great ambition of seeking to become stronger until he becomes the strongest being on the planet. His arrogance, however, makes him come off being quite incompetent and would ultimately lead him to his death.

When Bakuzan transformed into a monster, his bloodthirsty nature only evolved him into a more psychopathic and sadistic being, as he takes pleasure in torturing those weaker than him. Bakuzan initially seek to defeat everyone to prove he was the strongest, but upon learning from Gouketsu that there were monsters far stronger than him, he ultimately gave up on that goal and instead seek into a hobby of brutalizing lesser beings.

Powers and Abilities
Prior to becoming a monster, Bakuzan was well known for being a very strong martial artist, to the point where he earned himself a title that highlighted that fame. Though Bakuzan admitted that the likes of Suiryu were stronger than him, he has shown to possess the ability of surviving a multi consumption of Monster Cells, suggesting he had superhuman qualities.

When becoming a monster, Gouketsu noted his overall capablities to be that of a Dragon Level threat, though not as strong as he is.
