Tomura Shigaraki is the main villain of MHA. He is basically what Deku would've been like if he was a villain by being a successor to a well known villain, called All For One. He has a  sadistically malevolent and twisted personality. He doesn't agree with the world and the societies of a hero causing him to grow a strong hate for All-Might and all of the heroes due to him not being saved by one when he was vulnerable child that needed help. 

In this abridged, we still want to keep his original traits, as he's a villain and he needs them, but we also want to touch upon something with him. We want to write him as a man who is having mental health issues, not to make fun of the issues no, but to develop his character by using the trauma of his tortured past as a recurring theme for him struggling with it as he still has his father's hand on his face as a sign of regretting what had happened with his family and him struggling to move on. We want to play with that as the series goes on.

Voice types for character:  

I have two different voice preferences for this character:

Try to sound more like the Japanese VA for Shigaraki (Kōki Uchiyama). However having your own interpretation of the character is absolutely fine as long as it matches his abridged personality. 

OR

Try to make him sound like the Joker from the Batman series (Mark Himil/Troy Baker)
