8-Ball from BFB mainly has a negative attitude towards many things, such as when Mountainy was blamed for killing Minecraftian. He is also shown to be a bit competitive in Creative Commons, when he and some of his teammates are fighting over who will animate.
8-Ball in his original design was identical to the 8-Ball featured in BFB. In his current design however, he seems to have more brighter colors then his original. He also appears to be a #8 billiard ball, a ball used to play the table game Billiards (also called Pool.)
