Prosh

Debuting in the pages of X-Force #39 in 1994, Prosh is a Marvel creation from the Copper/Modern Age, born from the imaginative collaboration of Fabian Nicieza and Tony Daniel during one of the X-universe's most expansive and ambitious eras. With appearances stretching nearly two decades across titles like X-Force, X-Men Forever, and X-Force: Phalanx Covenant, this character carved out a quiet but persistent niche in Marvel's sprawling mutant mythology. Prosh keeps genuinely remarkable company — sharing pages with legends like Wolverine, Professor X, and Ship — which speaks to the caliber of stories this character has been woven into. A modest appearance count only adds to the intrigue, making every Prosh sighting feel like a genuine collector's discovery.
