Ready to Rumble is the forty-fifth episode of Ben 10.
After accidentally damaging Gwen's laptop, Ben enters a mutant wrestling competition as Four Arms to earn the money required to replace it, becoming an instant celebrity. During the tournament, he fights a pair of mutant brothers named Gaterboy and Porcupine who owe a mob boss named Mr. Beck the prize money, which Ben doesn't learn about until after defeating them. After learning the truth, Ben goes with them to stop a gang called "Collateral", defeating the gang and the mob boss as Ditto. In the end, after hearing his new friends talk about owning up to mistakes, Ben gives the prize money to the brothers and their mother. Returning home, he admits to what he did only to discover that the computer wasn't even broken in the first place. Gwen's thumbprint was the key to make it work again.
