Tsoi

Tsoi (voiced by James Sie) is one of the three minor villains of Teenage Mutant Ninja Turtles series and also one of the three secondary villains of the 2012 animated horror film Alvin and the Chipmunks: House of Hell and also a member of a Chinese American biker gang. Just like Sid and Fong, he was secretly working for the Foot Clan all along, so nobody would blown his cover.

Biography
In 2000, Tsoi, along with two male bikers named Fong (Andrew Kishino) and Sid (also played by Andrew Kishino), travels to Monterrey Park, California and stops in a convenience store. In the store, Tsoi takes to hassling customer named Brittany Miller (Christina Applegate), having both Sid and Fong restrain the girl's two younger sisters Jeanette (Anna Faris) and Eleanor (Amy Poehler). Having grabbed Jeanette's navy blue wallet when she attempted to throw it to Brittany, Tsoi taunts Brittany, making Brittany grudgingly ask for it back and address him as Tessa.

After Jeanette accidentally mangles their motorcycles (due to her clumsiness) as revenge for troubling her, Eleanor, and Brittany, Tsoi and his fellow bikers follow the three girls back to the suburbs of Riverside. Despite being reluctant to participate in his friends' plan to burn down the haunted house after siphoning gasoline from a red Mazda sedan, Tsoi, however, after being reassured by Fong that nobody will get injured, wanders off to look around. Going into the haunted house, Tsoi nonchalantly begins toying with some of the equipment lying around on the second floor, eventually climbing up onto the third floor, which leads to the attic. Finding a rope and rake used to hoist dry leaves, Tsoi begins swinging from it for fun, catching the attention of, and annoys Sid, who demands Tsoi to come down this instant, so they can help Fong in his revenge plans. Unseen by Sid, Tsoi was ultimately grabbed by Donald Walls (posing as Theodore Seville) and pulled back into the haunted house, where Theodore/Donald stabs him to an attic rafter by the throat with a sharp pitchfork. Shortly, before Theodore/Donald kills him too, Sid finds Tsoi's corpse, which Theodore/Donald later moves. Tsoi's corpse, was later found and eventually taken away by the paramedics.

Aftermath
Shortly, after his demise at the hands of Donald Walls (posing as Theodore Seville) in Alvin and the Chipmunks: House of Hell, Tsoi, along with Fong and Sid, eventually becomes one of Donald Walls' revenants in Alvin and the Chipmunks: Chinese American Zombies, where he and the others fights Casey Jones, Leonardo, Raphael, Donatello, Michelangelo, Alvin, Simon, Theodore, and Odious to the death.
