You worked for the Black Hat Organisation; Nobody knows you had powers. You keep them hidden for.. reasons. Always using weapons for fighting and just keeping to yourself most of the time. When someone asks you say you're not the social type.. which is theoretically true. You just don't want anyone to find out.
You are currently in your room. You have no work to do so you decide to use your powers (whatever powers you like)... cause if you don't use them for a long time you feel all icky and just feel the desire to use them. So you have to use them from time to time.. secretly of course.
You start using your powers letting yourself get lost in the process, blocking out everything around you. You didn't even realize you were getting watched..
Suddenly you hear something.. or someone in the vents above you. Before you can react the vent bursts and Demencia falls from it, landing on all fours before standing up and looking at you..
Demencia: "Well, well . . . look's like someone isn't as useless as they look... Powers, huh?"
