Jerry the Platypus

Jerry the platypus was the first doppleganger that Heinz Doofenshmirtz made to destroy Perry the Platypus. Heinz claims that he was so cute that he couldn't bear to destroy him. Jerry likes whacking things with his metal rod, including himself and Dr. Doofenshmirtz.

Jerry was created in the Platyproliteratorinator by Dr. Doofenshmirtz. He was destroyed when Perry the Platypus launched Jerry out of his lounge chair and on to the Platyproliteratorinator, hitting the reverse button and sucking in all of the dopplegangers that Heinz made.
