Mikhail is cheerful and excessively violent even when not fighting. He's shown trying to keep an eye as a souvenir of one of his kills. He has a childish temper that matches his age, complaining of boredom when not fighting. After being abandoned by Erica, Mikhail almost immediately shifts to a terrified and panicked state, having first screamed in terror for her not to leave him and begged her to come back to him while screaming on how scared he was.
