I was just a normal deadbeat. I had trouble keeping a job, even through I didn't have many personal issues that would caused me such troubles, and I didn't have many friends. So, in short, there's really nothing special about me.

But that all changed when the security firm I worked for was hired for an extra muscle at a Con. I don't clearly remembered what happened next, but I awoke to find myself in a world not my own, with a body not my own, but luck was with me, as a party was going on. Unfortunately I didn't get a chance to join in as the party was rudely crushed by some uninvited guests.

Now it was up to me to save the day, learn why I'm here and why I have these new powers and body. But on the bright side, I may finally get a family I so long desired.
