Dennis (Spongebob Squarepants)

Dennis the Hitman, (mainly known as Dennis) is the secondary antagonist of Nickelodeon's 11th feature film The SpongeBob SquarePants Movie. He is a murderous bounty hunter who was hired by Plankton to kill SpongeBob and Patrick and prevent the two from finding King Neptune's crown.

He was voiced by Alec Baldwin.

Biography
Dennis was an assassin who was hired by Plankton to kill SpongeBob SquarePants and Patrick Star, making his first appearance when Plankton told his computer wife Karen about having someone who would kill the heroes. The reason being that Plankton stole King Neptune's crown sold it to a forbidden land called Shell City and framed Eugene H. Krabs for the crime, so Neptune threatened to execute Mr. Krabs (via burning by fire) unless the crown was to be retrieved within a period of six days; Plankton, obviously, wanted Krabs to die of a painful and wrongful execution, and upon learning SpongeBob's and Patrick's journey to get the crown back, he knew that Neptune would discover that Plankton was the thief, so he sent Dennis after them.

Dennis first appears in the film after SpongeBob and Patrick left on a mission to bring the crown back to King Neptune, he inspects left behind sesame seeds from the Patty Wagon and the two gasoline workers insult his hat. Annoyed by this, he literally pulls their mouths off before resuming his search for SpongeBob and Patrick. He then follows the duo's trail to the Thug Tug, where he finds that SpongeBob and Patrick blew some bubbles before causing a fight. As he blows a bubble to verify that Spongebob and Patrick were there, Dennis meets up with Victor and his thugs, who threaten him for blowing a bubble, but Dennis just punches Victor into the Thug Tug, sinking it before leaving to find his targets.

Later in the film, SpongeBob and Patrick encountered Dennis for the first time during the middle of their journey. Dennis removes Spongebob and Patrick's mustaches that were used to become "men" (which are made of sea grass and given by Princess Mindy) from their faces, calling the duo out on their stupidity on the obviously fake mustaches, before advancing on them. When SpongeBob asks why Dennis wants to kill him and Patrick, Dennis explains Plankton hired him to do so, and in his overconfidence, he accidentally reveals to his victims that Plankton was the one who stole the crown and sent it to Shell City. Dennis then lifts up his foot to crush the duo with his "big" spike boot, only to be crushed by the Cyclops' "bigger boot".

After what has happened at Shell City, SpongeBob and Patrick escape and ride on the backside of David Hasselhoff, who speedily swims through the ocean in order to send them back to Bikini Bottom. During the middle of the swim, SpongeBob and Patrick see the boot of the Cyclops that he stepped on Dennis with. It stops behind his foot and lifts back to show Dennis, who is squished into a green pulp like Plankton always does when somebody steps on him. Dennis then detaches from the boot and onto Hasselhoff, revealing that he is still alive. He then tries to kill SpongeBob and Patrick a second time. Dennis grabs SpongeBob by the throat but the latter blows soap bubbles into the hitman's eyes, making him to toss SpongeBob, but Patrick manages to catch him. The enraged Dennis then corners SpongeBob on Hasselhoff's heel. As Dennis prepares to crush SpongeBob and Patrick with his cleated boot, he suddenly hears the honk of a boat's horn. Dennis turns around to see, to his horror, Hasselhoff swimming straight towards a catamaran. Dennis is struck by the catamaran and falls back into the sea below.

He made a non-physical cameo in a wanted poster in the SpongeBob episode "Call the Cops" meaning that he's still alive and is still operating as a mercenary.

Trivia
