Invincibility

Invincibility is the ability to be immune from being voted off or eliminated from Total Drama Island, Total Drama Action, or Total Drama World Tour. Invincibility is usually earned through completing a challenge better than the opposing team/opposing campers/opposing castmates.

Team Invincibility
Mostly, invincibility was obtained by a person, more than one person, or a team, for completing their challenge to win the prize for their entire team.

Individual Invincibility
After the teams split in No Pain, No Game and Dial M for Merger, Chris tells the campers that the competition will have campers only looking out for themselves. Thus, solo invincibility came into play. Everything from team invincibility tied in with this. The only difference was in winning solo invincibility, only the person that won it would be immune from being voted off and/or eliminated.
