I have three OCs, who all present some aspect of myself, in one way or another.
Whiplash is chill and open in a way that I wish I could be - an idealised version of my base personality, I guess.
Comet shares some key traits with me, most of all their open willingness to be silly. We're also both ace.
Nova has social anxiety and struggles with how introverted she is, a more negative key trait of mine. We also both tend to argue ourselves into a rage sometimes.
