[quote=ASTA]
Am I allowed to reject a proposed fight with characters equipped with outlandish and borderline-overpowered capabilities? Or is this restriction, of which is based solely on undisclosed issues and accusations of possible abuse on my behalf (which, frankly I'm still wholly ignorant of), only applicable to me and me only?

Anyone can refuse to fight someone. I wouldn't expect many fights if you reject the few people willing to fight giant metal robot cats who can manipulate dimensions though.
