Onyxx

Bursting onto the scene in 2009's high-stakes Dark Avengers / Uncanny X-Men: Utopia crossover event, Onyxx is a Modern Age Marvel creation brought to life by Matt Fraction and the powerhouse artistic team of Marc Silvestri and Michael Broussard. Their appearances span some weighty X-Men-adjacent territory — X-Men: Legacy and the Dark Avengers titles — putting them in the same charged pages as icons like Wolverine, Cyclops, and Kurt Wagner. Rare in the catalog with only a handful of recorded appearances, Onyxx is a collector's curiosity: a character born from one of Marvel's most turbulent mutant storylines, worth seeking out for fans who love digging into the deeper corners of the Utopia era.
