Yeah Soaron (I wonder if name is inspired by Sauron from LOTR).
That eagle robot was very funny and charismatic.
I suppose you're right about this show being quite a dark for a kids show, but that made it more awesome. I guess it shaped my taste as well, because I could never watch those Power Ranger stuff. Looked so cheesy compared to this.
Btw, I just did a little bit of research, and it seems they announced reboot for Captain Power (it's "new" name is: Phoenix Rising) at 2016. It even have a teaser trailer.
But nothing else, I could find.
