Piper

Piper is a mutate, a member of the Swamp Men that was changed by Magneto, that lived in the Savage Land, a tropical preserve hidden in Antarctica. In his first appearance as one of the Savage Land Mutates, Piper sent a monster to attack the X-Men and Ka-Zar.

Piper later aided Magneto, by causing dinosaurs to attack the Avengers in the Savage Land. With the Savage Land Mutates, Piper was later employed by Zaladane in her attempt to conquer the Savage Land. With the other Savage Land Mutates, Piper again aided Zaladane in battle with Magneto, Ka-Zar, and their allies.

The Piper can psionically control animals, using the music he plays on his set of pipes. Piper is a skilled musician, but is dependent on his music as a focus for his psionic powers.
