A jellyfish monster created by Finster, the Jellyfish Warrior could blast lasers from his fingertips as well as spray a toxic mist that was highly corrosive. In battle, he wielded an umbrella, which could deflect attacks as well as send enemies into another dimension where he was practically invulnerable. To escape his dimension, Zack blasted his umbrella with his Power Axe. Jellyfish Warrior seemed to have a weakness to the cold. He was destroyed by the Megazord's Power Sword. He was one of the many monsters that actually communicated with the Rangers, calling the Black Ranger "little mastodon".
Jellyfish Warrior was also among the monsters who aidedRita and Zedd's attack on the Vica Galaxy in "Countdown to Destruction" and was destroyed by Zordon's energy wave.
- Jellyfish comes from what is commonly referred to as "Zyu2" footage, and was not seen in the original Zyuranger.
