Molybdenum Professional, or "Molly" to her friends, is one of the many members of the Professional clan. A self trained alchemist and explorer, Molly has made a name for herself as a purveyor of useful tonics and potions for customers that range from aspiring adventurers to nobles. She deals in potions for enhanced abilities and powerful effects. Her own ample frame is helped along by a powerful elixir that grants her extra mobility despite her increased size. The only issue is that it tends to knock her metabolism out of whack which results in her eating herself into a rather ample state. We see her here starting to push the limits of what her serum can handle. But she's got a ways to go before she needs to start burning it off.
