Nonexisty

Nonexisty is one of the 30 recommended characters that could've joined the game in episodes "The Reveal" and "Reveal Novum".

However, he only placed 8th with 11 votes, which wasn’t enough to join. He was also up for voting to join the second season, but he only got 266 votes. Even if he had gotten enough, he still would be disqualified for being absent, and was the only character not in the original BFDI cast to be disqualified.

He had another chance at joining in "Welcome Back". He got 501 votes.

He is one of the two contestants not participating in Battle for BFDI, with the other being Evil Leafy.

Appearance and personality
Nonexisty does not exist and therefore has no appearance or personality.

However, Firey mentions that he tastes like peanut butter, implying that he at least has a taste, and Ruby mentions that he is male, implying that he at least has a gender.

Coiny
In "Yeah, Who? I Wanna Know", when he finds out that contestants not present, including Nonexisty, may not compete, Coiny sarcastically remarks that it's unfortunate.

Otherwise Coiny has never mentioned this character in any other episodes of BFDI.

Firey
In "A Leg Up in the Race", Firey indirectly mentioned Nonexisty, saying that he tasted like peanut butter.

Ruby
In "Reveal Novum", when the Announcer "flung" Nonexisty to the LOL, Ruby told him he missed him.

Nickel (II)
In One-Shot Wonder (inanimate insanity) Nonexisty helps Nickel escape the LOL.
