Geoff was a camper in Total Drama Island as a member of the Killer Bass. He later returned as a castmate in Total Drama Action, but was not placed on a team due to his early elimination, and did not qualify for Total Drama World Tour. He was a co-host on the Total Drama Aftermath. He was seen with the original contestants on a yacht in the first episode of Total Drama: Revenge of the Island. He was also a contestant and finalist on the spin-off series as a member of The Surfer Dudes with Brody. Geoff may not be the smartest contestant in the bunch, but he has a positive attitude, loves people, and is always up for any challenge Chris has in store. He has a habit of addressing everyone as "dude" or "bro/brah," depending on the gender. He is extremely fun-loving, believing that life is short and if someone "doesn't stop and have a party every Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday, they're going to regret it." Geoff's big heart doesn't exclude even the more reserved. However, given enoughmotivation, he won't hesitate to pay people back for their misdeeds. Geoff's caring way automatically clicks with Bridgette's, and upon the formation of their relationship, the two are inseparable ever since.
In Total Drama Action, his popularity with the others is threatened when Geoff becomes an egotistical, sadistic "Captain Hollywood" with a personality similar to that of Chris's. He mercilessly tortures the eliminated contestants on the Total Drama Aftermath chair for ratings, and even goes as far as insulting Bridgette, prompting her to end their union. It ends up being extremely short-lived though, as the group turns Geoff's own tool against him and reminds him of who he really is. He is also great at motivating people, especially his best friend Brody in the Ridonculous Race.
