While making your character, you can choose various powers that will be inherent to your character, such as levitation, command over certain elements, and much, much more. You'll need all of these too, because Paragon City (the game's playground, if you will) has been overrun by the Rikti. It seems that Paragon City was once the bastion of heroes, and in fact their breeding place. However, the alien Rikti have shown up to ruin all the fun, and in doing so they've infected the place with "bad guys" and converted some of the once good people of the town into miscreants. It will take thousands of people online to try to maintain the peace in this otherwise ruined town.
