[@Afro Samurai] Ok. So. While I like the way you wrote the backstory (and I really, really like it). There are a few problems with your CS. 

1. You have more than one power. I don't mind if your character is somehow more durable than normal humans but you raised him to a Luke Cage level. So. You basically have two powers. That is a no-no.

2. The aliens did war with humanity. They didn't come door to door to catch them. As soon as I get home I'll have the "Super hero catcher" unit displayed for everyone to see. But for now. Remember that the aliens attacked humanity. So, either Briggs hid from them and got captured eventually or he fought them and eventually he lost. He is human after all. 

Also. Not a problem but merely a praise/warning. Why I like the fact that you made Luke Cage, I encourage you to go for something more original if you want to do so.

Btw. Harlem is protected by Portal xD
