Rubberduck

Rubberduck is a duck superhero. He possesses the ability to stretch and contort his body into various shapes.His rubbery body makes him highly resistant to injury, though he can suffer painful damage if his body's elasticity is overtaxed (similar to severe muscle pulls). His powers are a permanent condition—i.e., he cannot turn his powers "off", though he can maintain his "normal" shape without effort. Thus, he is prone to being stretched against his will by someone stronger than he is, and can be restrained by essentially being tied up with himself (having his stretchy limbs wrapped around his body or an immovable object such as a tree, and tied into knots to prevent him from unwrapping them). He is a member of the Zoo Crew. His secret identity is Byrd Rentals.
