How is Luke Cage (Earth-2149) a zombie?
I don't know if this has already been discussed and I'm sorry if it has but, how is the Zombiverse Luke Cage been zombifyed? This is a guy who continuously boasts having un-breakable skin, and the virus wasn't airborne. Am I missing something? His page even says it's perculiar how he's beem zombifyed. []
