The bear

The Bear is as his name suggests a bear that is frequently seen in the woods surrounding Camp Wawanakwa and the surrounding areas (e.g. a mysterious island or Boney Island) interacting with the campers. His role will frequently change from a secondary antagonist in the show to a mere bystander. It's also of great debate if each appearance is the same bear or not. The Bear first appeared in The Big Sleep when Tyler had a lack of sleep-induced hallucination where he thought he saw the Bear pop out of a bush and maul Katie and Sadie to death although this was quickly revealed to be a hallucination. He later appeared in The Sucky Outdoors where Izzy first dressed up as the Bear to scare the campers although later the real Bear comes along. Although initially the campers believe it's another trick (this time courtesy of Chris) they do eventually realize it's a real Bear when they recall that Chris said that there were real Bears in the woods and when Owen in an attempt to prove he's a fake rips off a piece of hair and instead it becomes a bald patch. The Bear's next appearance is in Up The Creek where the campers take a ride to Boney Island and when the Screaming Gophers are fleeing from giant beavers the Bear who's rubbing his back against a tree doesn't believe what he saw and puts on a pair of glasses. When the campers then come running back fleeing from giant loons the Bear once more thinks his eyes are fooling him and destroys the glasses. He appears in the following episode "Paintball Deer Hunt" where he gets involved in the plot for the first time when he becomes the cause of Cody getting voted off. When Cody comes across the Bear in the woods he attempts to bribe it with berries at first but instead the Bear mauls him and leaves him in critical condition although he leaves him to finish off some of the potato chips that Cody was carrying (the chips' crumbs were actually what led the Bear to Cody in the first place). He doesn't appear again until much later in the series in the episode "No Pain, No Game" where at the end his name is revealed to Molotov by Chris (although since there's a debate about whether or not it's always the same bear he shall be referred to his adapted name) and he's the professional Russian log-rolling champion for 7 years running. At the climax of the episode where Leshawna has to survive on a log with Molotov for 10 seconds whilst avoiding certain death in piranha-infested water. Eventually though not only does Leshawna survive the given 10 seconds but also speeds up the log much to Molotov's discomfort and then jumps on it causing the log to roll over again whilst the stuck Molotov gets dipped in the piranha water causing him to get all his fur eaten clean off although he survives. At the end of the episode it's revealed he shares a cave with Sasquatchinakwa and he is shown wearing either Katie or Sadie's dress in an attempt to cover up his bald spots and then does their famous, "EEEEEEEE!" complete with clapping hands. In the following episode "Search And Do Not Destroy" where campers have to get keys from various life-threatening situations Owen is forced to get that's wrapped around the Bear's neck much to Owen's chagrin due to his phobia of bears. This ends badly for Owen since at the end of the episode Owen does retrieve the key but then the camera zooms out revealing that the entire lower half of his body is in the Bear's mouth. The bear is quickly subdued when the Camera Crew shoots him with several tranquilizer darts (humorously though one hits Owen giving him a monotonous expression for the remainder of the episode). During the episode "Wawanakwa Gone Wild" the Bear is mentioned frequently but seen only once and very briefly. During the episode Heather is tasked with capturing the Bear but this ends badly for Heather since she gets knocked unconscious with a shot the to the buttocks with a dart gun by Izzy whilst the Bear having been awakened by Duncan runs right past her in a rage. The Bear is seen briefly in Camp Castaways when the campers discover Chris' and Chef's secret campsite the Bear can be briefly seen eating some cake. The Bear's next appearance in the show was in I Triple Dog Dare You where Owen's dare was to give the Bear a purple nurple (much to Owen's chagrin). Owen complies and the Bear is seen chasing Owen out of his cave before rubbing his chest to steady the pain. The Bear's final appearance on the show was in "Total Drama Drama Drama Drama Island" where he appears as one of the episode's main antagonists (the other 2 being Courtney and Justin) although he isn't seen until the second half of the episode. Here Cody, Tyler, DJ and Owen get tangled up in the tethers of Courtney's hot air balloon although unfortunately the Bear quickly hops on as well. Eventually at the climax of the episode the balloon gets destroyed by a pilotless plane that was hijacked by Justin and although Courtney escapes the Bear is left in the cockpit as the balloon lands in the kitchen. However the Bear nonchalantly walks out and dusts his fur off as if nothing happened thus indicating he survived.
The bear appears in the TDA trailer when Gwen first asks if there will not be explosions, burning buildings, or bears. A building then catches on fire with a bear inside. It then chases Gwen, Trent, and Duncan.TH
