Ben 10: Alien ForceIn the team's first encounter of a Techadon robot, Gwen cut off its hand to save Kevin and before it can react, Goop enters it through the opening created by the severed hand then proceeded to enlarge himself, creating large amounts of pressure which in turn causes the large robot to explode causing a rain of Goop to fall. The hand Gwen had cut off was dumped in the trunk by Kevin. Cash and J.T. later trashed Kevin's car and stole the hand where it was worn as a gauntlet by Cash. It then took over Cash's mind, returning to the form it held before Ben and company interfered soon after the metal from the glove enveloped Cash's body. Trying to get revenge, Cash goes after Ben to take him down after Ben tries to stand up to him. While fighting Chromastone in the Mr. Smoothy parking lot, Chromastone manages to reach Cash just in time to save him. After which Ben stated that he would stash it away where no one would find it.
In Primus, Ben, Gwen and Kevin fought another Techadon. This one was red and it is revealed by Kevin that Techadons are mass-produced war robots. During the battle, the Techadon's hand tried to crawl off when the robot started to lose but Kevin destroyed it, remembering last time. Right before the Omnitrix teleported them to Primus, Kevin defeated the second Techadon by ripping its head off from the body.
Ben 10: Ultimate Alien
Techadons returned to Ultimate Alien in Greetings from Techadon, Vulkanus orders a Techadon factory shipped to Earth to create an army of Techadons to defeat Ben. Kevin defeats the first Techadon by throwing a model of the Tokyo Tower from a mini-golf course at it. Later Ben wraps the Ultimatrix with his coat, as the customized Techadon was targeting the Ultimatrix on his wrist. Kevin, then, placed an ID Mask which turned into an Ultimatrix symbol on Vulkanus' back. Then the Techadon targets Vulkanus and chases him.
In Inspector 13, a Weapon Master came to earth to investigate the recurring failure of Techadons on Earth. He discovered that Ben and the Omnitrix/Ultimatrix was responsible and sought it to reverse-engineer it as a weapon. He used the Techadon Factory he sent to Earth as part of Vulkanus's hit on Ben as a base. When the Ultimatrix malfunctioned, Ben started using Techadon parts as weapons against Techadon Weapon Mater Number 13, who in turn activated the factory and used the Techadons inside as an army against Ben.
Gwen as Rath and Kevin as AmpFibian, destroyed the robots and Ben was able to get the Ultimatrix working again, using it he forced the Weapons Master off earth. Kevin is also revealed to be keeping a Techadon in his garage.
Ben 10: Omniverse
They returned in The Ultimate Heist under the control of Inspector 13. Two were commanded to destroy Albedo (who wanted to steal a Polymorphic Crystal). However, he managed to defeat one with dodging the other one's attack. The other one managed to make Albedo fall from the truck.
Two robots were seen at 13's warehouse guarding the door. They were tricked by Argit and accidentally let Fistina and Solid Plugg infiltrate in. However, after Fistina opened the door the Techadons started to attack them but were defeated almost immediately.Three days before the events of Cough It Up, Argit stole a dehydrated Techadon army which had the shape of a cube. It revealed that this item is really important for Psyphon, so he sent bounty hunters after Argit. After the hunters caught Argit, he swallowed the cube in order to make Psyphon and the hunters let him go. Since Argit swallowed the army, it no longer remained dehydrated and started to grow inside of Argit's stomach. He then started to cough up cubes which transformed into a Techadon robots. Argit has full control over the robots. He commanded them to catch Psyphon and the bounty hunters and get them out of Undertown for good. They are orange with dark beige pads.
