Who is she? What does she do?
Bridgette is one of the original 22 contestants on the animated reality show, Total Drama. She is a member of the Killer Bass team of season one. Bridgette is kind to everyone and feels compassion even for people who have screwed her over.
She's a vegetarian who adores animals and mother nature. She was horrified when she found out that the hot dog dish in The Brunch of Disgustness challenge was made from dolphin and refused to eat it even at the cost of the challenge.
She is shown to disapprove violence and was for a time the only contestant on her team that didn't mess with Harold over his geeky and disgusting ways. As she showed disapproval when Duncan, Geoff and DJ (a pure good himself) we're pranking Harold over leaving his underwear around the cabin.
In "Action", when Geoff takes the position of Aftermath host to his head and becomes a narcissistic jerk not unlike Chris. Bridgette is shown to be nowhere near as easily corrupted and snaps Geoff back to normal reminding him about who he was.
Her animal kindness is shown again when she gets sent to Siberia. She tended to an injured polar bear and nursed him back to health. Bridgette was also the only character to feel bad for Blaineley after she got severely injured and had to be put in a dolly despite Blaineley being the one to kidnap her and send her to Siberia in the first place.
Admirable Standard?
Easily one of the most likable characters in-universe and out. Even Courtney likes her and is the only contestant who Courtney has remained friends with throughout the course of the series. Which is pretty surprising considering Courtney's reputation of betraying everyone close to her.
This is what makes Duncan specifically target her for elimination due to how popular and likable she is.
Heck, even a vicious polar bear acts overly protective of her after she heals his paw.
Corrupting Factors?
The only potential one is that she feel victim to Alejandro's manipulation in World Tour. Alejandro charmed her and she let her attraction of him get the better of her and kissed him while she was dating Geoff.
However she felt deep remorse for it and made amends for it in the form of one of the most heartwarming songs in the season.
