Transfixatroned was an episode where most of the Autobots got stuck in their vehicle modes.
Darth Grievous made a failed attempt to liberate the imprisoned Decepticons on Cybertron and was forced to retreat to Kalee. He ordered his robot army to get working on a new device that makes Transformers stuck in vehicle mode. He first tested it on Skywarp when Skywarp is in his jet plane mode and after a series of whining Darth Grievous freed Skywarp from his jet mode. Meanwhile after liberating Coruscant from the Sith the Jedi watched the Autobot Jets put on an air show above the liberated planets but during the air show Skywarp used the Transfixatron to disable almost all the Autobot Jets and Cars in their vehicle modes except Breakaway, Blaster, Bumblebee, Ratchet, Skyfire and Jazz. When the Sith Legion came by the Autobots couldn't transform to robot mode and were stuck in vehicle mode but Optimus Prime said the Autobots are not helpless. They tried to roll and fly to attack the Sith Legion but the Magnaguards had flatten their Tires and the Seekers destroyed their Stabilizers causing the Autobots to become helpless. After the Battle the Autobots were all captured and were taken to the Sith Legions base at Tatooine. The remaining Autobots and Jedi had to make a grenade that can counter the effects of the Transfixatron and then travel to Tatooine to test the grenade. At Tatooine Darth Grievous introduce a new device that will slowly tear apart the Autobots called the crusher. This device kills the Robots and turned them into scrap piles and when the Seekers first took Ironhide as the first victim the Autobots were somehow able to free Ironhide even if they can't transform. The Jedi and unaffected Autobots had arrived and was able to use the grenade to free the Autobots that are trapped in their vehicle modes. Furious Darth Grievous ordered the 3 evilleros to fuse together and order his biggest battle droids along with his infamous moneterous Giant Sombrero Robots to destroy the Autobots once and for all. The Autobots had a hard time stopping the Giant robots but when Skyfire noticed the giant robots weak points they hit the weak points and destroyed the robots and defeated the Super Evillero. Darth Grievous and his legion had to escape from Tatooine which caused the Jedi to liberate the enslaved species there. After destroying the Transfixatron the Autobots return to Cybertron for rest, repairs and recovery.
This episode is similar to the G1 Transformers Episode The Autobot Run only this time the Transfixatron affected almost all Autobot Jets and Cars.
