Re: Char: Power Girl
In the 80s the Earth-2 Kryptonians, while less powerful than the Earth-1 versions, could still do things like fly faster than light, break the time barrier, etc. From the looks of things the pre-Crisis characters that returned in Infinite Crisis retained those power levels, and as such the Earth-2 Superman would be WAY overpowered compared to the modern post-Crisis one. I don't know if Power Girl's abilities stabilized to match her cousin's after she found out her true origin (my tenure as a reader of DC Comics ended, not coincidentally, with the end of that series), but if so she'd be considerably more powerful than Supergirl.
