SKULLOMANIA

Skullomania was once an average salesman called Saburo Nishikoyama. His superiors were not pleased with his results as a salesman. Down on his luck and constantly under pressure for results, he volunteered to dress up and perform like a superhero at a carnival thrown for a top customer in their department store. He had hoped it would be chance to prove his value as a salesman. When he grabbed the attention of all in attendance, something clicked in him. Tired of his job, Skullomania decided to become a vigilante crime-fighter. Not much else is known of his past.

n Street Fighter EX2, like most other Arika characters, his storyline was changed. Instead of being a Japanese businessman, he was a defector from an army of an unknown nation. He and Shadowgeist are implied to be brothers.

Skullomania closely resembles a Japanese superhero called Kamen Rider, which interestingly enough, was based off of another character from the same creator called Skull Man.

Skullomania was officially used in the Arika game Technictix, released in Japan only. Skullomania also made an appearance in the PlayStation game, Fighter Maker, even with some of his special moves intact. His signature move is the Skullo Dream, an unblockable combo attack which is increasingly comedic in execution as the series progresses.

AREA

Area is a clever young woman, who is testing her father’s latest inventions, rocket skates, and a giant mechanical arm. She, along with Vulcano Rosso and Sagat made their first EX series appearance in Street Fighter EX2 Plus. Very little about Area's history, or why she enters the EX Tournaments is known. She appears to be the daughter of a very wealthy and creative inventor. Dismayed by his daughter's penchant for martial arts combat, he figures if he cannot dissuade her from entering tournaments, the least he can do is equip her with the latest in technological design to give her an edge.As a fighter, Area doesn't detest the enhancements, she embraces them, considering those who fight without technology to be primitive brutes. Not content to simply accept the inventions her father makes for her, she constantly tweaks and improves upon them between fights to her liking. She arrives into battle with mechanized roller blades, and a mini-rocket launcher on her arm.

Most fighters who are pit against her don't know which is more bizarre; her equipment, or her lust for battle at such a young age. Area is quick to prove that her technology is not something to be taken lightly, but she lacks the raw strength and talent that many more experienced fighters possess. While she could use her equipment as a blunt clubbing weapon, she is careful not to damage the delicate components that they are made out of. She finds herself easily overwhelmed by opponents who are not impressed with all of her gadgets.

ALLEN SNIDER

Allen Snider is a character who appears exclusively in the Street Fighter EX series by Arika. He debuted as a hidden character in the original Street Fighter EX. He also appears in the Arika-developed non-Capcom fighting game Fighting Layer. A martial artist once reputed to be the greatest living Karate master in the United States. Allen was the favored contender in the All American Martial Arts Tournament, but lost on his first match against a then-unknown Ken Masters, who told Allen that he was still a "big fish in a small pond".Motivated by Ken's words, Allen renewed his training and developed new techniques based on Ken's such as the Soul Force (Hadouken) and the Rising Dragon (Shoryuken). Allen began traveling the world to prove that he is not only the "biggest fish in his pond", but also the "biggest in the ocean".

He is based on Chuck Norris. He is the parallel to Ken as Dan is to Ryu, because Allen uses techniques copying the Hadouken and Shoryuken, wear a undershirt inside their gis, and they're voiced by Osamu Hosoi. But Dan is a parody of SNK's Art of Fighting series.
