A chaos beam should create a form of chaos energy such as chaos control, or chaos blast. A chaos beam should not create both of these simultaneously, much less inside of a hedgehog. This particular chaos beam, of course, chose to do the latter. OLD

Archieverse/SEGA-Sonic crossover. Lara-Su crushes on this reality's version of Sonic the Hedgehog. Perhaps she would be unnerved by such an infatuation, should she take the time to actually think about it. But she doesn't.
