Marv

"You remember Marv? He's one of yours. Sort of a fountain of youth in reverse."

- Fish introduces Marv to Peabody

Marv is a villain in the TV series Gotham. He is introduced in the third season as a henchman to Fish Mooney.

History
Marv was one of the inmates experimented on at Indian Hill. Marv was one of the few experiments that was turned by Miss Peabody and not by Strange. His powers allowed him to age every person he touches rapidly, eventually leading to their death. He is one of the escaped experiments from Indian Hill. As the others, he is releases when Fish Mooney's truck crashes in Gotham City. Afterwards, Marv joined Fish.

Together with Fish, another henchman and Selina Kyle, Marv enters a secret research facility where he ages a researcher to death. He escapes when James Gordon arrives.

Later, after Fish's men have kidnapped Peabody and brought her to an abandoned warehouse, Marv alongside other experiments watch when Fish interrogates her. Afterwards, Fish introduces Peabody to Marv and asks whether she recognizes her creation. Marv, who is wearing gloves to prevent killing accidentally, removes said gloves and touches Peabody, aging her until she drops to the ground dead. Moments later, Ivy Pepper is found spying and is captured. Fish orders Marv to deal with her and Marv pursues the escaping Ivy into the cellar. Although he is able to grab Ivy, she is able to wrenches free but stumbles of an edge. She falls into a broken sewer pipe and is immediately flushed away by the current.
