Worm is a villain from Marvel comics who first appeared in X-Men Vol.1 250.
Nothing is known about the past experiences of Worm. He was mutated in a fashion similar to the other Savage Land Mutates. The mutation was caused by a device created by the mutant known as Magneto, giving him superhuman powers and altering his appearance substantially somehow. He then joined with other similarly mutated super beings under their leader, Zaladane.
