- Voice Actor: Scott Page-Pagter
- Main Enemy: Zack Taylor
A woodpecker monster created by Finster. He would wave his wings around to create sudden storms and he would also use his extended beak as a weapon, pecking at the Power Rangers. After Zack got the idea to use a fake balloon that was actually filled with a special hard substance, the peckster tried to pop it and this resulted in his beak getting stuck. Rita made Peckster huge and this freed him from the bind, but he was destroyed by a swing of Megazord's Power Sword regardless, exploding in a burst of maniacal laughter. Tommy stayed out of this fight to preserve his unstable Green Ranger powers.
During the Rita and Zedd's marriage, Peckster assisted Rhinoblaster when guarding the Rangers in an abandoned theater, not at all menacing like before, but instead more of a monster version of Bulk and Skull.
Note: Peckster comes from what is commonly referred to as "Zyu2" footage, and was not seen in the original ZyuRanger.
