Blast (family problems)

Blast is a tall man with a muscular build, spiky, graying hair, and a light beard. He wears bulky armor with large shoulder pads, a large cape worn at the bottom, and emblems of his name on his chest and back. His suit has minor damage, presumably from his many battles. He also wears dark glasses and has a scar on his face between his eyes. His gloves have circles on the back of his fists, which form an infinity symbol when he presses them to teleport. The outline of his iris is a wavy black pattern, unlike the consistent outline seen in other characters.

Blast tends not to show up to Hero Association meetings. Like Saitama, Blast considers his hero work a hobby. He also seems to have independent tendencies, advising Tatsumaki to use her own powers to defend herself instead of waiting for others to save her, and only appearing on his own terms (in his case, according to Sitch, when humanity is in danger). Blast's attack on the ninja village also indicates that he shows no mercy to humans he sees as evil, similar to Amai Mask.

When he appears to Saitama, Flashy Flash, and Manako, Blast has a casual and calm demeanor, as he didn't seem bothered by the three touching the cube, even though they didn't know or accept the deal, and he was willing to explain what the object was. Blast wasn't affected by Flashy Flash's attempt to attack him, simply telling him to calm down, and he was willing to teleport them all out of the underground area they were in. Blast didn't question Saitama's presence as a Class-S hero; however, he momentarily became serious about Manako's presence with them since she is a monster. After Saitama's explanation, he quickly returns to his relaxed attitude and accepts what the bald hero said.
