Super Heroes Theme

[Shards-Of-Fate]

So I can fathom how to execute many super powers if I were to work on a Super Hero oriented server. Something like your City of Heroes / Champions Online. But I have a few questions to the scripters and concept people out there. How would you execute flight in an RPG setting? I mean, the DBZ RPG's let you fly over water. And that was the main need for it. Any other unique powers that could be utilized and bring some uniqueness to Graal?
