I believe there are certain things that DC editorial will never allow. Among these are 1) Killing off B-5, and 2) Allowing him to be something other than a 31st century version of his ancestor Vril Dox.

Ugh. And Saturn Girl's been Jean Greying it up, as well, abusing her powers to mindwipe allies, hinting at telekinesis, etc. Polar Boy's already taken a step towards forming an Iceman-esque ice-body, with his ice-arm, as well. Sun Boy and the Human Torch have progressed along similar 'playboy to burnout' arcs as well.
Soon Rokk is gonna put on a purple helmet and start prattling about Braalian racial superiority...
