Sidero Husbando

Sidero is a villain working for Flect Turn in My Hero Academia: World Heroes' Mission. Like most Humarise members, Sidero is devoted to carrying out Flect's plan. Although he presumably only joined the cult to avoid being killed for having a Quirk, as he was quick to offer information once captured by Heroes. Sidero's Quirk allows him to create and detach iron balls from his knuckles, which he can then enlarge in size and mass. He can detach them to provide ammo for Beros' Quirk.
