"Give it up Power Rangers, you'll never defeat Lord Zedd!"

Pirantishead was a piranha monster who served as the main antagonist of the three part opening episode of Season 2, "The Mutiny".


Pirantishead was created by Lord Zedd. When Lord Zedd took over palace of Rita Repulsa, he used his staff to transform pirahna in the lake on Earth into pirahna monster, Pirantishead. Zedd then sent monster to attack Angel Grove. Zedd wanted Pirantishead to turn Rangers's Zords against them. Pirantishead was one of the most formidable foes that Rangers ever face. He used chains-linked flutes, that could be used as nunchaks. Zedd seemed to continually feeding Pirantishead energy from his staff.

When Lord Zedd took over Rita Repulsa's palace, he used his staff to transform a piranha on Earth into Pirantishead. Pirantishead was one of the most formidable monsters the Rangers faced at that point. His weapon was a pair of chain-linked fish shaped flutes that doubled as nunchuks. During the course of his existance, Lord Zedd appeared to be continually feeding Pirantishead energy from his staff.

The Rangers encountered him in the city. Using the flute, Pirantishead was able to freeze the Saber-Toothed Tiger, Triceratops, Mastodon, and Pterodactyl Dinozords. He was then able to take control of the Tyrannosaurus Dinozord and Dragonzord and turn them against the Rangers. Pirantishead also took control over motorcycles of Bulk and Skull and made them ride in the circle. Billy was able to create a device to free the Dinozords from Pirantishead. To buy some time, the Rangers form the Power Blaster and fire at Pirantishead, first aiming at the Tyrannosaurus Dinozord, then Pirantishead who initially panics. Strangely enough, the Power Blaster blast mostly missed him, aimed a little low, but the explosion did burn his feet and cause him to hop around, howling in pain and glowing with electricity, implying that he was almost defeated. After the Zords are restored, Lord Zedd attempts to bury them deep into the Earth, but Alpha is able to save them and transform them into the new Thunderzords.

The Thunderzords battle Pirantishead (who appears to be drunk during the battle, based on his erratic, staggering motions) after testing out the controls, and fare much better, not even being knocked down once. The Thunder Megazord was able to destroy Pirantishead with its Thunder Saber. The Mutiny

Later, Pirantishead was revived by Lord Zedd along with other aquatic monsters such as Commander Crayfish, the Slippery Shark and the Goo Fish to make up his Fish Army. with help from the Tube Monster. They fought the Rangers at the beach, stalemating until the Rangers had to use their Thunder Megazord to kill the Tube Monster and left Tommy to fight the sea monsters alone. However, in spite of being heavily outnumbered, he easily took them down with Saba, making all of the monsters disappear in flashes of white lightning. A Reel Fish Story

Powers and Abilities

  • Durability: Pirantishead has extremely thick fish scale like skin that mjeant that, when blasted by the Power Blaster, he only performed an Irish jig.
  • Skilled Fighter: Pirantishead was a skilled enough fighter to easily be able to defeat the Rangers using his weapons, skills and the Dinozords.


  • Chains-linked Nunchaks Flutes: Pirantishead wields a pair of flutes that are connected by chains and double as nunchucks to use in combat.​​​​​ However, thier main function was controlling the Zords. The chains were destroyed by the Thunder Saber's electroctution attack and he discarded the blades.

    • Machine Control: Pirantishead can play his flute and blast Zords with a white mist that allows his complete control over them, He performed this on the Tyrannosaurus Dunozord and the Dragonzord.
      • Machine Freezing: Pirantishead can freeze machines in time using this same teqnique, as shown when he performed this on the other Dinozords.
    • Chain Wrap: Pirantishead can throw his chain which makes it wrap around his enemies, as shown when he did this to the Thunder Megazord.
      • Electrocution: Pirantishead can slam his fist down on the chain to send an electrical charge along it that electrocuted the Thunder Megazord.
  • Fins: Pirantishead has large and razor sharp fins protruding from his elbows that he claimed he would use to "tear apart" the Thunder Megazord but was destroyed before he could use them.

Behind the scenes



  • Pirantishead comes from what is commonly referred to as "Zyu2" footage, and was not seen in the original Zyuranger and was originally intended to have been destroyed by the original Ultrazord.
    • The dis-congruity in the Zords and monsters explains why the Megazord was seen and why the Thunder Megazord was briefly shown attacking Vase Face.
      • Recently released Zyu2 footage shows that Piranthishead did indeed fight Megazord & Dragonzord instead of the Thunder Megazord. In the fight Pirantishead once again takes control of Dragonzord and commanding it to fight the Megazord which explains why Dragonzord was absent during the fight with the Thunder Megazord.
  • Pirantishead's costume was later adorned with Hate Master's "hair," recolored blue, had the fins on the side of his head removed, and later used in background shots in the episodes "Fire in Your Tank" (where it was among the monsters in Divatox's boot camp) and "Countdown to Destruction" (where it was among the monsters in Rita Repulsa and Lord Zedd's army). Fans have named this monster "Blue Grouperhead."
