Rongruffle is a character who first appeared in "The Bounty". She is a bounty hunter who formerly worked for Lord Hater to capture Wander and Sylvia, but Commander Peepers kept messing with her plans.
In "The Bounty", Rongruffle was hired, along with Killbot 86 and the Potted Plant, to capture Wander and Sylvia after Hater became displeased with Commander Peepers' constant failure. Commander Peepers then made it his goal to stop the bounty hunters to ensure that they would not take his place as Hater's second-in-command. Rongruffle became Peepers first target after she found Wander and Sylvia in an amusement park. She attempted to subdue them by tranquilizing them with her sleeping darts, however Peepers continually stopped her darts with coins and Rongruffle eventually became aware of this. She then pursued Peepers into a beast's pit where it was revealed that her skull belonged to a member of the beast's species. The beast then proceeded to maul Rongruffle while Peepers made his escape.
In "The Gift", Rongruffle was shown to have survived her encounter and was one of the many individuals whom Wander and Sylvia gave a present to and she appeared quite happy with her gift.
