I really liked this animation. Honestly, CT reminds me a bit of One Punch Man in his OPness. The one thing OPM has though that CT seems to have not is a worthy rival capable of pushing him beyond his limits.
Or at least something that gives him a run for his money.
I read a previous comment by Mega and I have to agree. You put CT in a position in that it's almost impossible for him to feel challenged with anything else. My advice is maybe enter something that alters the proteins in CT's DNA for a while that makes him temporarily vulnerable. This way CT cannot just stroll through situations and is actually fearful of what's to come, adding another depth to his character.
