The Mutant
In Reality Z-25 31-H, the Mutant was a weird, genetically-engineered creature, the work of Professor Madison. Resembling a large round head with a huge mouth, two beady eyes, and two legs, the Mutant was engineered for the sole purpose of being immune to dangerous teleportation and vortex-travel effects. Thus, to keep fragile items safe while jumping through a wormhole or portal, one would temporarily feed them to the Mutant, take the Mutant along, then have the Mutant spit them out.
Madison first unveiled the Mutant during her trip with the Terrific Two, Rodney Rabbit, Terry Tornado and Mysto the Space-Wizard to the Nexus of Realities. After the adventure, Rodney tried to befriend the weird creation of his employer and lover, though it did not seem very enthused by the movie he'd set up for the two of them to watch.
