|This article is about a/an monster in Mighty Morphin Power Rangers.|
Oysterizer was an oyster monster awakened by Rita Repulsa. He guarded his pearls of power. In battle, he could fire from the holes on his body an acidic gel that can burn through anything. He fought with the Megazord briefly underwater after growing on his own accord, where he had the upper hand. However, Dragonzord (who lived underwater) was able to knock him back onto dry land. Here, the Megazord was able to defeat him with the Power Sword.
He later attended Master Vile's End of the World party.
Years later, he was one of many monsters who were attempting to take over the universe for the United Alliance of Evil. He was seen in the army of Rita and Zedd and the army of the Machine Empire.
Oysterizer was also seen on Onyx as one of the monsters trying to bid on the Pink Quasar Saber.
He was seen among the monsters in the Shadow World.
- Oysterizer comes from what is commonly referred to as "Zyu2" footage, and was not seen in the original Zyuranger. Recently released Zyu2 footage shows that Zach used his scanner built into his helmet to find the Oysterizer while it was in the water.
- Oysterizer was the final monster to be fought by the original Megazord.
