Gwen and Heather are on superior teams (Screaming Gophers, Screaming Gaffers, and Team Amazon) in all of the first three seasons. The same goes for DJ and Harold, (Killer Bass, Screaming Gaffers, Team Victory) and Owen and Izzy. (Screaming Gophers, Killer Grips, Team Chris is Really, Really, Really, Really, Hot) Though Izzy had to swap teams in Seasons 1 and 3 to acheive this.
Duncan has received more symbols of immunity than any other contestant in the whole series. He recieved thirteen marshmallows in Total Drama Island, two in Total Drama All-Stars, and eight Gilded Chris Awards in Total Drama Action, making a total of twenty three.
Owen is the only contestant that reaches 3rd place in a season that doesn't also appear in every episode of that season, as Heather ranked 3rd in Total Drama Island and appeared in every episode, and Cody ranked 3rd in Total Drama World Tour and appeared in every episode.
Duncan is the only contestant to make it to the Final Five more than twice. He also did so three seasons in a row. He ranked 4th in Total Drama Island, 2nd in Total Drama Action, and 5th in Total Drama World Tour.
Gwen is the only member of Total Drama All Star's Final Four to not have been in the Final Six in the previous season she competed in, as Mike, Scott, and Zoey were all members of Total Drama Revenge Of The Island's Final Six.
Lindsay is the only member of Team Victory to compete in Total Drama All-Stars, as everyone else who returned from Total Drama World Tour was from Team Amazon and Team Chris is Really, Really, Really, Really Hot.
The Killer Grips, Team Victory, and the Toxic Rats are all record inferior teams, as the Killer Grips only won three challenges while the Screaming Gaffers won eight, the Toxic Rats only won two challenges while the Mutant Maggots won six, but while Team Victory also won just two challenges, it is the worst because it is the only team in TD history to be completely wiped out before the merge.
Counting Noah and Owen's participation in "The Ridonculous Race", Trent is the only Screaming Gopher to not make single-digit rankings in the seasons he competes in, nor does he make it farther than Episode 17 at any point.
None of the female contestants have been eliminated regularly in "Total Drama: Pahkitew Island". Firstly, Amy was eliminated, when Sammy tricked everyone that they were each other. When Amy came back to the show, Chris disqualified both sisters, to avoid any confusion. This sent Sammy home as well. Later on, Ella was disqualified, when Sugar sent Chris a letter explaining that Ella was singing, when Chris told her not to. After the merge, Scarlett was personally eliminated by Chris, after trying to take over Pahkitew Island. Later, Jasmine was automatically eliminated, after Sugar knocked a tree down on her. Eventually, Sugar would fall victim to her own elimination, when Chris deems her talent as unruly, giving her the lowest score. Finally, Sky made it to the final two and won "Total Drama: Pahkitew Island".
Team Kinosewak is the first team to be consisted entirely of women at one point before the merge. This was the reverse of Team Chris is Really, Really, Really, Really Hot (after Izzy, the only girl on the team, was eliminated) and Toxic Rats (for "Runaway Model" only, as Jo would be on that team), in which both teams consisted solely of men.
With the exception of "African Lying Safari", Duncan has been eliminated in different ways. In TDI, Chef Hatchet chose Duncan for elimination. Duncan would win the next season (TDA). However, he would end up quitting TDWT, because he didn't want to sing, after dealing with Courtney and Gwen's feud. In the All-Star season, Duncan ended up getting removed from the show for blowing up Chris' mansion.
Owen and Heather are the only contestants, as well as season winners, to make it to the Final Three more than once. They also made it to the Final 10 three seasons in a row. Owen won TDI, ranked 3rd in TDA, and ranked 8th in TDWT. Heather ranked 3rd in TDI, ranked 9th in TDA, and won TDWT.
Noah and Trent are the only Screaming Gophers to never make it to the Final 7 in the seasons they compete in. They aslo both ranked 11th in separate seasons. Trent ranked 11th in Total Drama Island, and Noah ranked 11th in Total Drama World Tour.
Gwen has had more guys find her attractive than any other girl on the show. Throughout the series, six guys have found her attractive at some point: Trent and Gwen were in a relationship for a majority of season one, and the beginning of season two, before they broke up. Cody has a big crush on her. Owen constantly calls Gwen a hot chick, and Tyler agrees with him in the EX-Files. Harold confesses that he finds Gwen attractive in the Chefshank Redemption after she smashes a shovel over his head. Duncan and Gwen were in a romantic relationship from the EX-Files to Moon Madness. He also called her a hot chick multiple times before they became a couple.
Cody is the only character voiced by Peter Oldring to not rank 18th in a season, as Tyler ranked 18th in Total Drama Island, and Ezekiel ranked 18th in Total Drama World Tour. In addition, Cody outranks both of them in both seasons they compete in, and he is the only one to make it to a single digit ranking.
Cody is the only member of Total Drama World Tour's Final Four to not lose his hair at some point in time. Heather's was shaved off by Chef in I Triple Dog Dare You, Sierra's was burned out when she blew up the plane in Aww DrumHELLER, and Alejandro's was burned out when he was caught in the lava flow in the end of Hawaiin Punch.
In Total Drama World Tour, Team Amazon didn't lose a single member until Picnic at Hanging Dork, the 16th episode of the season. Thus, Team Amazon lasted longer than the other two teams without losing any of its members.
With the exception of Harold, all the members of the Screaming Gaffers were irregularly eliminated in Total Drama Island. DJ was automatically eliminated, Leshawna was accidentally voted off by the eliminated contestants at Playa Des Losers, Duncan was eliminated by Chef Hatchet, Heather is eliminated due to a technicality from losing a challenge, and Gwen was one of the finalists and was thus never eliminated.
Courtney is the only member of Team Amazon to be voted out normally. Gwen was eliminated via tiebreaker, Sierra was eliminated by Chris, Cody was eliminated when he lost to Alejandro in the first challenge in Hawaiin Punch, and Heather was a finalist, and was thus never eliminated.
Both times Cody was eliminated, an animal attacked him. In Paintball Deer Hunter, he was attacked by a bear, resulting in his team thinking he wasn't useful anymore and him being voted off. In Hawaiian Punch, Alejandro knocked Cody into the water and he was eaten by a shark, (Until Sierra saved him) resulting in his second elimination.
Geoff and Gwen are the only members of Total Drama Island's Final Seven to not have been in the Final 10 of Total Drama Action, as Izzy, Leshawna, Duncan, Heather and Owen all did make it to the Final 10.
Only 8 contestants have outranked Owen at least once. Those contestants are Alejandro, Beth, Blaineley, Cody, Courtney, Duncan, Heather, and Sierra. Coincidentally, Seven of them were Total Drama World Tour's Final Seven, and Beth is the only one that doesn't compete in TDWT.
