Blind Tiger

Benjamin Tanaka, better known as Blind Tiger, is a Japanese-American superhero who protects Zone 13, primarily its industrial sector, the "Bricks". He was born blind, but through genetic experiments, gained superhuman senses of hearing, touch, and smell. He is also a master of martial arts and swordfighting, wielding a katana as his primary weapon.

Origin & History
Tanaka had a complicated birth and was born blind. At the age of 6, his biological parents are murdered by the Sawscale Vipers, a criminal organization/gang, and he was kidnapped by the gang and handed over to a shady research facility that performed extensive neurological experiments on him, resulting in heightened senses, which he uses to fight his captors and escape. He was then found, adopted and raised by Satoru Tanaka, the master of a martial arts dojo, a kind father figure who trains him to be a deadly warrior.

Once again, the Sawscale Vipers bring tragedy into Ben's life, attacking the dojo and slaughtering Satoru and a number of his disciples. Ben remains at the dojo as it rebuilds for several years, but eventually cannot ignore the hatred inside of him and follows the Vipers, who have allegedly relocated to America, the capital city's breeding grounds for crime, Zone 13.

Abilities
Beyond his heightened senses, Tanaka is deadly with a sword and his fists, leveraging his blindness to his advantage. It is said that he can "hear ants crawling on the ground, smell your fear, and feel the gust of wind from a sword before it strikes."
