Wonder Blob

Spot is an extraterrestrial creature only referred to as a "Wonder Blob".

Biology
Spot is asymmetrical in its eyes, with one of the eyes protruding on a eye stalk. The creature itself has three main forms:

Infantile Form
Spot's infant form is completely harmless towards other creatures. It is the size of a frog, with greenish skin with a set of long legs with sharpened claws. It has two black eyes, and a small mouth filled with sharp teeth.

Adult Form
When matured, Spot's skin is now white with several tentacles acting as legs, and a long set of arms.

Giant form
The final form of Spot has a resemblance much to that of a dinosaur, growing as large as a building, and with a more pronounced body.

History
As an infant, Spot was found and held captive by Humans of the TALOS organization, with it being used as a source of alien DNA for use in genetic experiments. During this, however, it manages to bite one of the scientists, and as it grows into its adult form manages to escape.

This incident was what birthed the Mutant.
