Brane and Quark

Two fox brothers, they live in one of many Zipt universes. Quark knows of his "atomic" abilities for a while already - he can manipulate his state of aggregation, split into small particles, infuse with things and even change into other existing species, being limited only by his own mass. His overgrown younger brother Brane (M-theory term), however, just recently learned of his brushie abilities, so he's not as good with that... yet. He doesn't know that in his case he's probably a tiny bit stronger than Quark, since he can manipulate his dimensional state (although he cannot shapeshift, only keep his original shape somewhat)
