Melter

A young villain introduced during Marvel's Dark Reign era, Melter possesses the ability to melt objects and people, and sought membership with the Young Avengers — though his motives and moral alignment proved far more dangerous than heroic.

Melter stepped onto the Marvel stage in 2009's Dark Reign: Young Avengers #1, a Modern Age creation from writer Paul Cornell and artist Mark Brooks born right in the thick of one of Marvel's most morally complicated eras. Over a publishing history stretching across fifteen years, this character has kept genuinely fierce company — sharing pages with the likes of Wolverine, Sabretooth, and Nekra — which tells you something about the dangerous corners of the Marvel Universe Melter tends to inhabit. With appearances across Wolverine and Trials of X alongside the debut miniseries, Melter occupies a niche but persistent place in the modern Marvel tapestry, the kind of character that rewards the dedicated reader who digs deeper than the household names.
