Over the series, Nickel has had various changes made to his character.
In BFB, Nickel seems to be far more spastic than in previous seasons, sometimes spouting nonsensical sayings and phrases. He also cannot easily tell when someone's being sarcastic.
However, Nickel becomes more cynical and unamused after "This Episode Is About Basketball", believing that they won't be able to win challenges and doesn't have as much fun on the show as he did previously.
Battle for Dream Island
Nickel made his first appearance in the episode. His motto in the promotion is "I'm going to be the new Coiny!".
This is also the only time he has arms in the show(s).
Battle for Dream Island Again
Yeah, who? I Wanna Know
Nickel makes it into the second season and ends up being on Team No-Name, which wins this challenge.
