Robogoat

Robogoat was a mythical cyborg goat brought to life from an illustration in Tommy's "Myths and Legends" book by Lord Zedd. He was sent to battle the Rangers and steal their Sword of Power. Though successful(and able to beat Tommy and capture Billy, Zack, Trini and Kimberly), Robogoat eventually lost the sword back to Jason, which forced Zedd to make him grow. He clobbered the Thunder Megazord pretty severely, but the Rangers recovered. He was destroyed by the Thunder Megazord.

 * Main Enemy: Tommy Oliver and Jason Lee Scott

Robogoat was later resurrected in "Zedd's Monster Mash" as one of the monsters in Doomstone's haunted forest. He attacked an unmorphed Tommy, along with Pumpkin Rapper, and they took his Morpher to keep him from turning into the White Ranger. However, when the Pink and Blue Rangers arrived to help, Robogoat was knocked down by a flipping kick from the Pink Ranger and he did not get up again to attack afterwards. Robogoat would return as one of the monsters fighting the captive Power Rangers in the Specter Theater for Rita and Zedd's wedding. Robogoat briefly left the Theater to attend the wedding of Rita Repulsa and Lord Zedd, but he went back to unsuccessfully try to recapture the Rangers when they escaped. Robogoat was one of the six monsters to grow large in part 3 of "The Wedding", where he met his end by the White Tigerzord's fire blasts. Despite his destruction, Robogoat would return one final time to attend Master Vile's End of the World party at the Juice Bar in season three's "Master Vile and the Metallic Armor, Part III".

The Robogoat suit was later repainted brown, horn-removed, and fur-added where it was used in the episodes "Fire in your Tank", "Heir to the Throne," and "Countdown to Destruction"

Trivia

 * Robogoat comes from what is commonly referred to as "Zyu2" footage, and was not seen in the original Zyuranger. There was originally footage of the Dragonzord, and the Ultrazord was to destroy Robogoat.
