Oil Bot is an enlarged oil-themed Attack Bot. This bot was attacking the city in his giant form. The Rangers responded with the Zenith Megazord, but the Attack Bot had the advantage with his slippery oil making the Megazord loose its footing. he blasted the Megazord, causing the Rangers to have to separate back to their individual Zords.
Upon Doctor K's orders, the Rangers formed the High Octane & ValveMax Megazords. They used their Megazord's finishing attacks to destroy the Attack Bot.
