Gwody

Gwody is the het ship between Gwen and Cody Anderson from the Total Drama fandom.

Total Drama Island
Cody develops an interest in Gwen fairly early on, due to being put on the same team. Gwen, however, doesn't seem to reciprocate, instead having feelings for another competitor, Trent. Cody is still persistent, doing his best to get Gwen's attention and hit on her. Gwen, on the other hand, describes him as an annoying little brother, but concedes that he is one of the few sane people in the competition with her, and that he is a nice guy.

In the episode Up the Creek, Cody manages to get Gwen paired up with him for the canoe challenge, partially hoping to get her bra to win a dare with Owen. He soon realizes Gwen's disappointment at not being with Trent, and at a stopping point, offers to switch partners, allowing Gwen to continue on with Trent, and Trent agrees. Gwen is thankful, and gives Cody her bra. Cody resolves that although Gwen is his dream girl, he isn't her dream guy, and he simply wants to help her be happy.

Total Drama Action reveals that Cody still has Gwen's bra.

Total Drama World Tour
With Gwen's break up with Trent during Total Drama Action, Cody returns to his attempts to date Gwen, now that he has returned to the competition and they once again are placed on the same team. Gwen is unsure, mostly being confused with her possible feelings for Duncan, but tells Cody once again that she appreciated him helping her and Trent get together.

The introduction of Sierra starts to limit their interactions, Sierra pushing Gwen away from Cody any time the two try to have friendly interactions. Gwen finds Sierra's obessive crush on Cody somewhat amusing, but also is considerably weirded out by how far the girl goes.

Fanon
The ship sailed as a result of Cody's canon attraction to Gwen, as well as their constant friendship throughout the series. Although rivaled by more official ships for Gwen, Gwent and Gwuncan, and sometimes other ships for Cody like Coderra and NoCo, many people enjoy the idea of the two getting together now that Gwen has had unsuccessfully relationships and broken up with both Trent and Duncan, especially considering the rather negative attitudes of both exes leading to the break up. Those upset with Duncan's behavior during World Tour also like to pair Gwen with Cody instead, disliking Duncan's cheating and instead preferring Gwen with someone nicer.

Trivia

 * It's been stated on Total Drama's official social media that Cody apparently has no romantic feelings for Gwen after the third season. However, whether that's actually true in canon remains unknown.
