Marvel's Luke Cage: 44 Easter Eggs You Probably Missed
15. Diamondback
Like Cottonmouth, Diamondback is a long-running Power Man villain.
Diamondback's name in the comics comes from his mastery of knives, and though it's not a big part of his character in the show, he does kill off a gangster pretty memorably with a knife through the face.
Instead of his rivalry with Cage over Reva, instead Diamondback is reimagined as his half-brother, with definite shades of Loki-itis-like jealousy of the favoured son.
We also see Diamondback wearing a suit based on his comic book look in the final showdown, with the help of a Hammertech suit clearly provided by whoever is running Hammer's company while he's in Seagate.
Looks like he's going to come back with a force in season 2 after what Dr Burstein does to him.
