Biography
The Strangler is first seen littering in the Krusty Krab parking lot and is arrested after SpongeBob tells on him. Squidward (Rodger Bumpass) then tells SpongeBob (Tom Kenny) of how the Strangler will kill anybody who tells on him, as SpongeBob witnesses him making threats in the back seat of the back seat of the police car. As SpongeBob and the police officers turn around, they realize that the Strangler has escaped, and the police subsequently abandon SpongeBob.

After numerous failed attempts to get a bodyguard to protect him from the Strangler, the Strangler himself, wearing a fake mustache and poses himself as a bodyguard, gets SpongeBob to hire him, though SpongeBob is unaware that it is the Strangler in disguise. The Strangler then tries to strangle SpongeBob, however, figuring that there are too many witnesses around, he decides that they should move themselves to somewhere secluded. SpongeBob suggests his house, which the Strangler approves of, although SpongeBob says he has to perform a few errands first.

Following the drawn out errands, SpongeBob fails to find his house key, leading to the Strangler suggesting that they break in through the window. SpongeBob then jumps onto the Strangler's eyes using spiky boots, injuring him. After sticking to the Strangler for 6 hours straight, SpongeBob apologizes and then decides to grab the key under his door mat, infuriating the Strangler. The Strangler then believes the two of them to be alone and prepares to kill SpongeBob, only to realize that his friends were planning a surprise party for him. The Strangler waits the party out and attempts to kill SpongeBob once more, however, his friends return to throw another party soon afterwards. As the party ends, the Strangler tried to strangle SpongeBob, only for Patrick (Bill Fagerbakke) to arrive. Impatiently, the Strangler tries to force Patrick to leave, unintentionally tricking him into believing that he is really the Strangler.

When SpongeBob makes opprobrious remarks on Patrick being the Strangler, being frustrated to no end, the Strangler rips off his fake mustache and reveals his identity, only to run out of SpongeBob's house when he does not realize who he is and his friends try to throw another party. The Strangler attempts to run away from SpongeBob, but is followed by him to no end, eventually ending up in a jail cell as SpongeBob shows up to see him, still thinking that the Strangler is his bodyguard and the Strangler confesses that he is not really his bodyguard and tells him that he's really the Strangler as seen on the "Wanted" poster, much to SpongeBob's horror. The Strangler then willingly stays in prison as the police congratulate SpongeBob for putting him behind bars. The Strangler eventually becomes thankful that he is away from the yellow idiot, and Patrick, who is also in the cell, asks him what he is in for.

He returns 14 1/2 years later in "The Krusty Slammer", where he's among a platoon of prisoners/inmates living at The Krusty Krab, where Mr. Krabs (Clancy Brown) turns it into a prison, but for Plankton (Douglas Lawrence) only. He's first seen in a cell next to Plankton's former crocodile colleague, Reggie. Later during mail call, he thanks Spongebob for giving him a letter in unison with his prison colleagues. We then see him relaxing in his cell drinking a lemonade like he's in a spa. We also see him watch Krabs cause a food fight with prisoners and his own customers, he's among throwing tomatoes at him. The next morning, as Krabs comes back to the restaurant, he and the prisoners surprise him by smiling and waving to him after being kicked out last night. The Strangler is last seen witnessing Krabs being escorted to the Chum Bucket as Plankton's prisoner.
