Nikolai is the second child to Natalia and Shouta Aizawa.

Nikolai is a very quiet kid who keeps things to himself. He is cursed with his father's cold blank expression that usually intimidates people but he has his mother's kind heart. Despite him being a child to two of this most reconizable pro heroes, Nik has no interest in being a pro hero. He enjoys his quiet middle school life and has no plans in changing in the future.

Though due to his quiet obsession with cat cafes, Shouta and Natalia always joke about how he's gonna end up owning one someday.

Quirk

Black Ice is a combonation of an ice quirk and a shadow quirk. Gaining this from Natalia's side of the family. (wip)

Side Effects The side effects are really terrible. Due to it being a very cold quirk, Nik is constantly freezing. If he uses his quirk too much, he will get major frost bite. Overusing it would result in his organs to turn to ice and his bones breaking and shattering. Almost like you have to treat him if he's a person made of glass.
