While serving prison time for a crime he didn't commit, former gang member Carl Lucas volunteered for an experiment that gave him enhanced strength and unbreakable skin. He promptly used his new abilities to escape prison, returning to his boyhood streets of Harlem.Marvel Source
Rather than returning to crime, he took the name Luke Cage and became a mercenary "hero for hire," using his powers to help anyone who could afford his asking price.
Eventually cleared of his criminal charges, Cage has distinguished himself in various superhero groups (including, most recently, the New Avengers), but in the end, he's nobody's man but his own and is currently a loving and devoted father to his daughter Danielle whom his wife and fellow superhero Jessica Jones gave birth to.
Key binds look like this:
Tactics are easy. Cold Shoulder in, Cage Was Here to clear the trash, Belt Buckle to build up combo points, Harlem Dropkick with max points. Rinse, repeat. For bosses (or in any tight spot), use Heroes for Hire -- I actually need to relax my discipline on this, as it's up so often that I can afford to be less conservative with it.
This is a leveling build, and I'm still leveling, so I don't know how it does for top-tier content.
For costume affixes, I've gone with all defensive affixes. Cage needs a little help in that department.
