Kevin Keene and Link met Pero in a saloon, where he helped them avoid a fight with one of the locals. They, in turn, rescued Pero from Count Gruemon's henchcats, so he agreed to help them recover Kevin's Power Pad and Zapper by luring Count Gruemon to them. He accompanied Kevin and Link through the Old West, Captain Long John Slither's pirate ship, and his world's versions of London and New York City in search of a warp back to his own time, but was forced to steal the timeship after Dr. Gari-Gari sealed the warp. Feeling guilty about turning his back on his companions, he returned Kevin's equipment, told him how to defeat Dr. Gari-Gari's pet serpent, and gave Kevin and Link directions to Hyrule.
After crash-landing the timeship in the desert, Pero ran off with his map in search of another warp to his own time.
