Soga has a cruel and violent personality and likes to humiliate and attack people. This stems from the fact that he has been discriminated against due to his actions and his quirk. He seems to think that everyone around him sees him as some sort of monster and has developed a love of making other people suffer in place of him due to these circumstances. He shows some signs of mental instability, as shown when he sees everyone around him with a mocking, condescending smile, and laughing at him, no matter who they are and what they are actually doing, suggesting that he is unable to separate reality from his perception of the world. It is suggested that this perception of the world is what makes him so violent. In spite of these flaws, he shows solidarity with his friends, who he takes a leadership role for. He feels kinship with others who have been looked down upon due to their quirks. He shows a strong sense of loyalty and care towards them. 

Soga is also very defiant when he knows he is being played. Later on, he changes for the better, and became a valuable ally to the Vigilantes. As a result, he became somewhat of a vigilante himself. He has developed a firm sense of identity and ideology as a vigilante, lecturing those he thinks needs it. He believes vigilantes are necessary to those who slip through the cracks of the imperfect institutions. He has a complicated relationship with the police, as he knows they're fighting for the same cause and will occasionally help them, though if he disagrees the police's methods, he'll refuse to cooperate. Soga doesn't care for the legal definition of a villain, refusing to acknowledge someone as such if he believes they are undeserving.

Soga is a 20-year old boy. I would like him to have a medium/kind of lower pitched voice, so not too deep or not too high.
