Luke Cage, Power Man

Unbreakable Skin — Whenever Luke Cage attacks alone, he gets +2/+0 and gains indestructible until end of turn. (Damage and effects that say "destroy" don't destroy him.)

"People call me with their problems. They feel the cops don't care, the Avengers got bigger issues, and Spidey's number isn't listed. But they have my number, so they call me."
