Full Plot

At first, Ryan discovers he has a power that controls technology with his mind. He next learns that he can use his technopath power to pilot Mech-X4. He learns how to control Mech-X4 and uses its power to grab a dumpster and spilling it on Mark. He feels like a "monster" because Mark said he would never embarrass him like how he embarrassed Mark.

At Bay City High, an actual monster comes. At that moment, Ryan gets into Mech-X4 to fight Jaguasaur. They don't manage so well and they realize they need a fourth member which has to be a mechanic. When Ryan throws a dumpster at Jaguasaur to get it away from the girl it was about to eat, Mark figures out it was Ryan who emptied the garbage on Mark. When Mark fixes the repairs on the robot, the MECH-X4 Team successfully defeat the monster.

Ryan apologies and welcomes Mark to the team. Ryan and Mark saw on the news that civilians of Bay City think that Mech-X4 is dangerous. Ryan comes up with a plan to help the civilians of Bay City like getting a frisbee from a tree and stop a thief stealing someone's bag.

When Ryan saves Marty from falling, Seth Harper becomes intrigued by the robot. Seth invites the robot and Principal Grey finds out where they are going to and is planning Octiconta attack on them. They find the monster and Harris gets himself trapped.

Ryan, however, thinks he was killed and blames himself for it for not listening. They find out Harris is still alive and Mark goes after him. They manage to defeat the monster using the Plasma Ax, but the other half disappeared.
