What is the origin of your character’s powers? What turned you to villainy?
Introduced to anarchy by a community college class, Kay fell in love with its philosophy. It changed his view on life and he dropped his business degree to pursue self-enlightenment, learning about the boundaries of life and how to break through them. Freedom was best. Life is too short not to do what you want.
Years later, having vastly improved his skills, scavenging wasn't enough to fill his stomach. He continually stole and shoplifted when he needed to, racking up a criminal record. He was offered thieving jobs, which he took for either fun or profit.
After one particular job concerning a private collector of art, he gave the client what he wanted and, as was his usual custom, took home his own personal trophy: the Mask of Sceadu.
The Mask of Sceadu is a mysterious artifact of untold power. Kay put it on as a joke to see how he would look in it. It bonded with him and marked his rise from freelance thief to the thieving supervillain "Criminal".
The Mask of Sceadu is permanently bonded to Kay Locke and this bond cannot be severed unless he experiences true death. Kay can summon the mask, manifesting it through darkness or shadow (though their presence isn't required), but he must put it on to gain access to its powers.
What were you doing during the invasion?
With everyone worried about the invasion, a lot of places were left unprotected or lacking in security. Criminal took the opportunity to go on a stealing spree.
What were you doing when you were caught? and how, or why were you caught?
Criminal was gathering information in a V'sori-controlled media outlet when he was ambushed--the outlet was a trap. The V'sori wanted local superhumans caught due and released false rumors about sensitive information being stored there. He was one of those who fell for it.
What makes him a villain? He doesn't seem so bad....
True. He seems to be more of a rebellious sort and is an anarchist at heart, but what qualifies him as a villain is, quite simply, his own selfishness and lack of moral code. Everything is acceptable, nothing is 'evil' as long as it's something he wants or finds worthwhile.
He advocates true freedom for everyone, but most importantly himself.
