I uh. ( how does one truly explain technically being the reincarnated son of the scarlet witch who made kids out of pieces of mephisto's soul, but born and raised in a nice, jewish family, having a brother he found in a juvenile hall somewhere who isn't biologically related to him but identical aside from hair/eye color with the same power as said witch's brother, and all of that. ) Mine's from chaos magic? There isn't really an inheritance rule, and the aging thing definitely doesn't apply. I use mine a lot and I haven't aged rapidly or anything.

( he demonstrates by raising a hand, even. blue flickers around his fingers before enclosing his clothes. they shimmer for a moment, before shifting into. well his superhero costume. the galaxy print isn't quite fabric, but moves independently of billy. when he shifts, so do they, like they're connected to some area of space. )

Congrats on the new pet.
