Light Yagami

Light Yagami is one of the main characters featured in the anime house series. Light, portrayed by Mark, is a commonly featured character, and is often seen attempting to dissuade others of the notion that he is Kira.

Personality
Light, to most of the anime house, is seen as a kind individual who wants nothing more than to hang out with his friends in the anime house. In actuality, Light is more like his anime counterpart, a ruthless, cunning, and a psychopath who seeks justice for the innocents of the world by killing off the evil. Light is even shown killing the rest of the characters featured in a false "dream".

Powers & Abilities
Light, much like his anime counterpart possesses the Death Note, which kills whoever's name is written down. Light also possesses near-superhuman levels of intelligence, and much like L, is capable of using deductive reasoning to an almost unmatched level.

Light has a strong sense of justice, and, according to Armin, is at the top of every top ten smartest anime characters list. Light's main goal of the Anime House series is to try to find a way to kill L (which he temporarily succeeded at doing) after he begins suspecting light of being Kira.

Trivia

 * Light is one of the only characters who has appeared in every Anime House video thus far.
 * It is unknown how the other characters aren't aware that Light uses the death note, as most of the others are aware of each others' abilities in their respective anime.
 * Despite the death note only working on humans in the actual anime, it is seen working on characters such as Goku (a saiyan), and Aizen (a soul/shinigami).
