Invading Chimera (M&M)
An alien predator infiltrates a camp by assuming the forms and mannerisms of nearby living creatures. Intelligent and deadly, it uses deception and violence to survive while concealing its true form: a formless mass of protoplasm whose genetic intelligence exists in every cell. Even a surviving drop of blood can allow it to endure. Designed as a Power Level 7 supervillain for a Mutants & Masterminds game, this threat includes powers, abilities, ambitions, goals, and three adventure ideas for introducing the creature as an adaptable and persistent enemy.
