The Godson Prodigy Dazzledeath

One dimension, two dimensions, three dimensions, seven. You are a child genius who theorized how to access the seventh dimension. In your spare time you compose piano music in the dark ambient genre. Even though you're smart, you're still a kid and enjoy movies about piranhas and ice hockey. You do part time work for The Commonwealth of the Arachnid Queen because they offered you a near unlimited supply of spare parts.
