The episode starts with Ben and Gwen playing a Sumo Slammers match, which Ben wins by distracting Gwen. Max consoles Gwen's loss and calls Ben's win not a real victory. He tells them about wrestling, before going to sleep.
Ben and Gwen see a poster for a wrestling tournament, the Midwest Wrestling Smackdown. Ben decides to participate in it and turns into XLR8 and stitches himself a costume, calling himself "The Crushster". Ben transforms into Four Arms while in the costume. Gwen and Ben leave the RV, hoping to win a $1,000 prize. While at the arena, Gwen becomes Ben's cornerman, and she tells him what to do. Ben, as Four Arms, ends up defeating several opponents and is moved up to the final round, against Iron Kyle.
While fighting Iron Kyle, Four Arms is thrown around the arena. Once it is revealed that he has four arms, the audience and Four Arms' previous opponents boo him, accusing him of cheating. Gwen temporarily distracts Iron Kyle, allowing Four Arms to knock him to the ground. Four Arms attempts to end the match but reverts back to Ben while on Iron Kyle's chest. Iron Kyle starts chasing him. When Ben accidentally spits at Iron Kyle, he notices his weakness to electricity.
Ben transforms into Overflow and shoots water at Iron Kyle, knocking the suit off of him and revealing him to be a "nerd". The audience reacts in shock to this sudden revelation, with some expressing grief due to now knowing the true nature of "Iron" Kyle. Kyle is ultimately disqualified for use of robot enhancements, and Ben is disqualified for his usage of Alien technology. After being kicked out of the arena, Ben and Kyle have an argument over who was cheating, with them eventually fighting each other in Sumo Slammers. The episode ends with Max asking who Kyle is.
Four Arms: What are you doing? Gwen: I'm your corner-person.. (changing her tone) This is how a corner-person talks. Four Arms: Like old men? Gwen: In the movies, yeah.
Gwen:(talking about Iron Kyle) He's trying to get in your head, kid. Four Arms: Well, it's working. When do I fight him?
Bill: The Crushster kid just turned into some kind of walking waterpark and our mighty Iron Kyle has... been revealed to be *sniff*... Just a nerd in a robot suit! Steve: It wasn't a metaphor at all, Bill. His body was literally made out of iron, I mean, how could we had been so gullible... Kyle: Heh heh... Hey everybody, it's me, uh, Iron Kyle! Iron Kyle! No? Okay...
Ben: You built a giant robot suit just to win wrestling matches? Could you be anymore of a cheater!. Kyle: You're one to talk, Mr. "I turn into aliens" guy. Ben: You were hurting people! Kyle: I was winning! Something you won't know anything about.
