Rojobot is a robotic monster, who served Mesogog and was created by Zeltrax. He serves as the main antagonist of the episode "Leader of the Whack" in Power Rangers Dino Thunder.


Rojobot was created by Zeltrax. Rojobot was intended to be the most aggressive monster, but he was actually just a coward. Wen he was created, he complained on the cold temperature of Mesogog's lair and was scared by Mesogog, calling him "big scary lizard". Mesogog sent Rojobot with an army of Tyrannodrones to find the radioactive meteorite that could alter personality. Rojobot attacked three Power Rangers (Tommy was frozen by Trent) and Trent in the forest with an army of Tyrannodrones and battled them. During the fight Rojobot was blasted by radiation of the meteorite and it altered his personality, making him more aggressive and wishing to fight. Then Rojobot left. Rangers were also blasted and started behaving strangely. Rojobot returned to Mesogog and Mesogog was angered by Rojobot's failure, but Rojobot wanted to destroy the Rangers and it impressed Mesogog. Then Mesogog sent Rojobot to attack Reefside and he encountered the rangers. Rojobot used his lasers and tentacles in battle. Rangers were losing the fight because of their altered personalities, but Hayley helped her friends and rangers defeated Rojobot, by using Super Dino Mode and finishing him with Z-Rex Blaster. Mesogog revived Rojobot and he battled Thundersaurus Megazord, but Trent helped his friends, as he was blasted by radiation and temporarily regained his good personality. Trent attacked Rojobot by using DinoStegazord and Rojobot was destroyed by Double Drill Attack of Anylozord Formation of DinoStegazord. Leader of the Whack
