When Sion intervened, Gaymark took Hayato prisoner to keep Argo under his thumb. In the end, Sion manage to save Hayato and defeat Gaymark before he was the brought in by TimeJet Gamma/TimeRobo Alpha. Around New Year's Eve, Gaymark managed to break out of his confinement capsule, thanks to the land lady, though he was still in miniature form. Once the Timerangers found out, Gaymark took TimeRobo as a hostage. He almost escaped, were it not for Domon's foot crushing him at the last second. The flattened Geymark was then put back into storage.
