I'll try applying one character for now. I have an idea for another one, but I'll wait a bit before I go through with it.

[*]Name: Elliot Teagon[/*]
[*]Nickname: Elite[/*]
[*]"Game Master" Title: The Arbiter[/*]
[*]Gender: Male[/*]
[*]Chosen Game Mastery: Halo (Spefically 2, which was the only one where he beat the campaign. The fact that the Arbiter is the playable character for the last level might be the reason why he has his weapons instead of Master Chief's)[/*]
[*]Preferred Weapon(s)/Power-Up(s): Elliot takes upon the Arbiter's (and by extension, the Elites) signature weapon: [url=http://static1.wikia.nocookie.net/__cb20120225164008/halo/images/d/d8/Espada_de_Energ%C3%ADa.png]The Energy Sword.[/url] Or rather, he takes [i]two[/i] of Arbiter's signature weapons... As in he dual wields Energy Swords. The swords can slice and dice practically anything with armor due to its magnetized ion-filled electron-based gas forming its blade. The downsides, asides from his need to get close with the weapons, is the fact that they drain energy every time they're used, and must be recharged every now and then. Another downside is that because the blade is magnetic, any magentic field will more than likely screw it up. He also shares the Arbiter's camoflauge, built into his armor. Much like the swords, his camoflage only lasts a short while before it powers off and needs to be recharged. It could also power off when Elliot attacks. Due to the high energy output of his swords, Elliot is not completely invisible so long as he holds onto his glowing blue swords.[/*]
[*]Background: Elliot, to say the least, lived a bored life. Not a boring life. But a bored life. After getting a certificate in a simple "sit in four classes for one year" course, Elliot had no idea what to do next. Getting a job, going for another course, all those just seemed... doable. But Elliot felt a lack of fun in his heart, something both those things don't seem to give him. Eventually, he came across a gaming club devoted to FPSes and joined it. Although COD was the game that the club played, one person brought in Halo 4, just for variety. This caused a surge of nostalgia for Elliot, who remembered getting Halo 2 and an Xbox for Christmas. Eventually, after seeing Elliot and his friend play Halo, everyone else decided to hold a Halo tournament. However, because Halo played differntly than COD, Elliot managed to wipe the floor with them. This earned him his nickname of Elite. Sastified with his fun, he decided to apply for a summer job... riiiight after he goes to this marathon everyone seems to be raving about.[/*]
[*]Other: Despite the Arbiter levels being more stealth-based, Elliot runs in guns blazing, or in his case, swords blazing. He also had a nasty encounter with the Flood in the campaign, resulting in him getting easily frightened when zombies and small brain like things are involved.[/*]
