Champions Online site has just launched a brand new section devoted to the various power sets that will be an integral part of character creation and gameplay. Right now only the Electricity power set is on show but the other powers will be revealed "over the next few days". The Electricity page contains twelve different powers, with full information on their requirements and effects. Positively shocking stuff.
Once the rest of the power sets are detailed, it will be time for fans to flip through the pages, meticulously weighing up the advantages of each particular power. Or, they could just choose whichever seems coolest. Or, they could hit up the open beta (which really isn't too far away now) and go nuts trying them all.
