- "They're this gang of bikers who pretty much stays on the south side of town. And thank God, 'cause they're sort of dangerous. Drug dealers and petty thieves."
- —Kevin to Veronica[src]
At one point, prior to Jason's murder, FP became their leader after he was forced to resign from Andrews Construction. This is because he had become too much of a liability to the company due to his criminal activities.
After Polly Cooper became pregnant, Jason Blossom went to the Serpents, he needed money for him and Polly to runaway together. The Serpents used him to run drugs which FP later clarified to be marijuana as a clean-cut kid like him would never be suspected. However, the last batch of drugs they had given him was never delivered, and they figured he had just run off with them, until his corpse washed up at Sweetwater River.
Season One Edit
The Serpents were hired by Hiram Lodge to decrease the value of the Twilight Drive-In, so that Lodge Industries could purchase the land for a low price. They were successful in doing so and the drive-in was shutdown. On closing night, members of the gang attended, being loud and disruptive. At the same time FP met with Hermione Lodge for payment of their services, but according to FP she was short. Also on closing night, one of their members, Joaquin, became involved in a romantic relationship with Sheriff Keller's son Kevin.
After FP was rehired at Andrews Construction, Hermione wondered if he was there to shake her down for the supposed money she still owed him. However, FP explained that he had already been compensated by Hiram.
Under the assumption that the Southside Serpents had attacked Moose Mason at Andrews Construction, Archie, Kevin, and Moose made their way into a local bar, Whyte Wyrm, which was a known hang out for Serpents, in search for the two guys that ambushed Moose. However, they picked a fight with the wrong Serpent, a member named Mustang didn't appreciate Archie's accusations, claiming that he wasn't the first Bulldog to come there and start trouble, he was alluding to Jason Blossom. Mustang shoved Archie, and then threw him on to the pool table just as their leader, FP instructed them to stop fighting. FP would later discover that the guys that attacked Moose were from Montreal, they were affiliates of Hiram Lodge.
