Doughboy

Doughboy is an experiment of Arnim Zola's. The creature is a solid protoplasm, able to shift shape and extrude psuedopods to attack or snare an opponent. The creature has a mouth, but not necessarily as a requirement for eating, but for attacking.

All of Arnim Zola's creatures have an instability in their cellular structure which renders them vulnerable to energy blasts of a certain signature, identical to the energy signature of her bio-energy blasts.

Its unclear if Doughboy is a discrete creature, or part of a more complex super-set of creatures, like the ones which attacked Ellis Island.
