 What happened to Madelyn in the aftermath is left unrevealed.Puff (voiced by Kimberly Brooks) is a woman whose exposure to the Big-Bang granted her the ability to either partially or completely transmute her body back and forth from her human state into a mass of living gas, in which state, Puff can become as light as air, allowing her to fly and become somewhat intangible.This also makes her vulnerable to water or large gusts of wind when she's in her gaseous state.
