Blackthorn

Stepping out of the Modern Age Marvel cosmos in 2000, Blackthorn made their debut in Len Kaminski and Oscar Jimenez's Avataars: Covenant of the Shield, an imaginative series that reimagined the Marvel universe through a fantastical alternate-reality lens. With only a handful of appearances — including a nod in the Official Handbook of the Marvel Universe: Alternate Universes 2005 — Blackthorn is a rare, collector-worthy figure who shares the page with the likes of Captain Avalon, Witchfire, and alternate-reality spins on Spider-Man and Iron Man. That kind of company in a short-lived but creatively ambitious series makes Blackthorn exactly the sort of deep-cut discovery that reminds you why digging through the corners of Marvel's multiverse is always worth the effort.
