Maniac Mechanic

On Earth, Maniac Mechanic disguised himself as Manny, a classmate in Ashley's shop class, and then stole her new wrench and made into his own weapon, the Wretched Wrench. Riding on the back of the Battle Wagon that he built, he used the wrench to knock out the wheels of Storm Blaster while Justin, Ashley and Carlos were on it. After it was eventually fixed, the Rangers were able to take down Maniac Mechanic by destroying the Battle Wagon, and at that point Ashley's wrench was returned to normal. The torpedoes were then fired to make the Maniac giant. The Rangers destroyed him with the Rescue Megazord.
