Foolx8

Foolx8 is the smart, evil and maniac X-Antibody counterpart of Fooly8. He is quite a showoff and most of his schemes involve proving he is better than anybody else, though they are clumsily stopped by the Propellor Cap Trio, even if they are much, much less intelligent.

Background
On the day of his greatest adventure, Fooly accidentally crashed into a gigantic snow pile, tainted with the X-Virus. Unlike many other penguins, Fooly sneezed a dark green blob almost immediately. It formed into Foolx. Foolx was evil in nature, so he escaped as quickly as possible to begin doing evil, skipping most conversations usual had in the births of other X-Antibodies.

Determined to prove he is better than anyone else, he became allies with Explorer 767 while he was under the influence of his BOSS XeXeXe form. Wearing a cheap mask, Foolx challenged Fooly to a duel. Foolx was defeated quickly, but swore revenge against Fooly, Fuzzle and the Flipplings.

Appearance
Foolx is an almost exact replica of Fooly, except for his darker feather color and purple propellor cap. And the fact that he always looks angry, in contrast to Fooly's cheerful nature.

Involvement
Foolx always claims he is the best creature in the whole universe and is completely perfect. He always tries to impose this idea on anyone through diabolical means, which are almost always ruined by Fooly, Fuzzle and Folly in extremely random ways. Due to this, Foolx completely hates this gang and tries to kill them. But unfortunately for him, he did NOT inherit the Fourth Wall powers of Fooly, leaving him to a serious disadvantage, no matter how smart he is.

Sometimes wearing a mask for no reason other than to look edgier, Foolx ditched his melee strategy from his first battle, after learning that Fooly preferred attacking from far but using his Whackhammer when things got desperate. Since the, Foolx uses different machines, called "X-Bots", to fulfill his jobs. His most successful models, known as QWERTY type and UIOP type, often fail. Yes, those are his most successful ones.

Nightmare Epic
Foolx was one of many X-Antibodies taken by Xplorer and controlled by Nightmare. In the final battle, he fought the Propellor Cap Trio before snapping out of it. He then proceeded to cowardly retreat, telling everyone in the vicinity, no exceptions, that they are "not worth fighting" and that they should "get to his level". Even to the X-Antibodies.

Trivia
