8-Ball

I don't have a favorite number, I really don't. 8-Ball is a contestant on Battle for BFDI. He was one of the 30 recommended characters who had a chance to join the game during The Reveal and Reveal Novum. However, he failed to become a contestant, coincidentally getting only 8 votes and placing about 26th, along with Book. 8-Ball also had a chance to join Battle for Dream Island Again, but he failed again, placing 29th with only 154 votes and was flung into the Locker of Losers.

Appearance
8-Ball appears to be a #8 billiard ball, a ball used to play the table game Billiards (also called Pool). 8-Ball, along with Match, Dora, David, Teardrop, Blocky, Donut, and Pen, were the only eliminated contestants to not be (heavily) redesigned in IDFB.

Personality
8-Ball is usually more or less quiet, although he always wants everyone to know that he does not have a favorite number despite his name. He speaks with a bland, metallic, monotone voice, except when in A Better Name Than That he nearly lost it in Today's Very Special Episode. In Getting Teardrop to Talk, 8-Ball successfully managed the team after Golf Ball's death without being too controlling or bossy. 8-Ball's excellent leadership gives him the title of team captain in Lick Your Way to Freedom.

However, he became a contrarian to Golf Ball in later episodes. It was later revealed that he was joking and trying to add humor to his team the entire time. The other team members still obeyed him rather than Golf Ball, causing the team to almost lose twice. 8-Ball's attempts at humor show that he tries to lift the spirit of the team and boost morale, though he comes across as somewhat dim-witted at not seeing the negative effects of his sarcasm.

BFB
In "Getting Teardrop to Talk", he appoints himself as team leader after Blocky kills Golf Ball, and successfully helps the team get the basket to X.

In "Lick Your Way to Freedom", the team known as appointed him as the new and current team leader, due to Golf Ball not treating Grassy with respect.

In "Why Would You Do This on a Swingset", 8-Ball takes advantage of his place as the team leader and orders his team to do the opposite of whatever Golf Ball says, beginning this spree of sarcasm, much to Golf Ball's dismay.

In "Today's Very Special Episode", 8-Ball once again does the opposite of what Golf Ball says about not loafing around until the timer is about to reach 0:00. After his team barely passed, 8-Ball suddenly drops his bland voice and apologizes to the team about how he didn't listen to Golf Ball's original command to go to work and nearly lost because of him. Golf Ball realizes that 8-Ball doesn't always have his bland, robotic voice and maybe a bad leader after all but her deduction was ignored by the rest of her team, except Robot Flower.

In "Four Goes Too Far", when Golf Ball tells to get on his rocket, 8-Ball jokingly commands the team to do the opposite, which causes Golf Ball to get somewhat upset.

In "The Liar Ball You Don't Want", while contestants from team throw instructions at Tennis Ball who is trying to control Remote to defend their goals in the challenge, 8-Ball informs them that they are doing their best.
