|This article is about a/an monster in Power Rangers Mystic Force.|
The Hydra Worm was the creature that dug the tunnels in the Underworld. Morticon sent this creature to dig its way to the surface world. While doing so, it attack Clare in the forest, though luckily she was saved by Phineas. When Nick went to investigate what had attacked Clare, the worm returned to attack him. Nick morphed and tried to take on the Hydra Worm himself, but he was outmatched. The other Rangers were able to rescue him just in time. Then, the Mystic Rangers morphed into their Mystic Titan Dragon Formation. The Mystic Phoenix rode on the Dragon into battle, and with Dragon Blast kicked at the Hydra Worm, the monster was destroyed.
