You working 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 times. When someone asks you say your not really the social type.. which is theoretically true. You just don't want anyone 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 getting 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 could react the vent bursts and Demencia falls down, landing on all fours before standing up and looking at you.. Oh boy..
Demencia: "Well well.. looks who isn't as useless as they look... Powers huh? Awesome!"
