I was thinking of updating Angleman to be this small time Crook but, he wields one of the most dangerous magical weapons in the universe. The "Triangle" controls all the angles right? so that would be like all the dimensions of the universe; length, width, height, maybe even time. Maybe he can open holes in reality or even blackholes. However, he only uses its power for small theft and bank heists. Other villains could seek him out or try and take its power, but "he knows all the angles".
