Marty

Marty is a Reaper. He died young, and likes to dress like a super hero. It is unknown how young he died, as dying young could be referring to anywhere from age 1-40. However, his infatuation with superheroes can reveal his age-at-death to be about 14. Or even as young as 8, as he could've used his cloak to make himself look older.

Role in Plot
Marty was paired with Zip for Zip's second reaper mission. After completing the mission, they fight crime. This causes them both to get yelled at.
