Pyro

Chase, commonly known as Pyro, is an American Gladiator.

History
He dated Luann for a time after she divorced from Kirk. When Bart and Pyro first met, Pyro impressed Bart when he revealed that smashing a chair against his didn't even cause him to flinch. Bart later attempted to repeat the trick on Homer while he was bathing. Homer, however, ended up crying in agony.

When Otto (dressed as State Comptroller Atkins) asked the audience at Lisa's award ceremony if any of them have ever cheated on their wives or husbands, Kirk was seen glaring at Pyro and Luann implying their relationship started before the divorce.

The Springfield children announced on the radio that Luann was cheating on him with his best friend Gyro. Despite this, Pyro and Luann were still seen together up until Luann got back together with Kirk.

Despite being Kirk's rival, Chase defended Kirk when the latter was attacked by Homer, Chase was then attacked by Barney Gumble.

He entered the contest to become the new Duffman. He nearly won. However, it was discovered he had a tattoo for an Ogdenville beer and was disqualified.

Behind the Laughter
He is a parody of the real-life gladiator, Nitro.
