Freakshow possessed the mutant ability to transform into monstrous creatures, and by doing so he could increase his strength and durability. He could fly and have other exceptional abilities depending on the creature that he chose to transformed into.
Freakshow was one of the few mutants to survive the Sentinels' attack of the deep-water harbor of Hammer Bay, on the island of Genosha. He would later befriend the mutant female known as Wicked from the Genoshian guards. He was discovered by Professor X and joined his efforts to rebuild Genosha. Freakshow was among the mutants that lost their mutants abilities due to the Scarlet Witch's reality altering catastrophe known as M-Day. Quicksilver's use of the Terrigen Mists returned his powers, but left him trapped in the form of a hideous creature.
