Matt

Matt (マット, Matto) is Mello's friend who lends him aid on the Kira case.

Appearance
Matt has brown hair and dark blue eyes. He is seen wearing a red and black striped long-sleeved top, blue pants and white goggles with amber-tinted lenses. He also wears black gloves that reach just below the elbow, as well as a pair of black boots and a cream-colored, sleeveless vest with a fur trim.

In the manga, he is seen wearing a black-and-white striped long-sleeved top and his hair is red.

In the video game, Death Note: Successor to L, Matt has blue-grey hair, but otherwise looks the same, though his eyes are never visible.

Character
Matt is Mello's assistant and helped him in the Kira case. Matt is very intelligent, known as the third smartest child at Wammy's House, and the third successor to L. His specialty is technology, and he is tasked by Mello to monitor the activities of Misa, Mogi and Aizawa.

He is shown to have a dry sense of humor; asking, "Since when were the Japanese allowed to have such big guns?" while standing at gunpoint. Matt is confident, and his cockiness while monitoring multiple computer screens at once is what leads him to make a few mistakes.

In the manga, Matt's hideout is shown to be littered with junk food and a box of cereal. Matt smokes cigarettes, and is seen doing so even while driving. Matt enjoys and is often seen playing video games, and he dislikes going outside. Takeshi Obata described Matt's concept as a "young man who loves gaming and doesn't really care much about the world."

Plot
Matt is first seen in the manga as Mello's accomplice in spying on Misa Amane, and later, Mogi and Aizawa. Matt follows Misa and observes her shopping with Mogi, then calls Mello with his cell phone. Matt describes Misa as "cute" and states that her age appears to be anywhere from fourteen to twenty years old. Later on, Matt calls Mello again, having been watching Mogi and Aizawa via camera. He informs Mello that the two have come out of the building and are having what appears to be a serious conversation. Matt makes another phone call to Mello after having let his guard down and losing track of Misa and Mogi who used a delivery truck as a disguise to sneak out of the building. Matt then follows Mello to Japan in their pursuit.

He is only seen again during Takada's kidnapping, where he distracts her bodyguards with a smoke grenade launcher, allowing Mello to kidnap her. When he was cornered, he tried to put up another smokescreen. Matt calmly surrenders but was shot multiple times. In the anime, he hid a gun inside the back of his shirt which he tried to take out. The bodyguards later state that they never intended on bringing him in alive because of their belief and loyalty to Kira, claiming that Matt wouldn't reveal anything about the kidnapping and that death was the only punishment for his crimes against Kira. Mello later sees the news of his death broadcast on TV, and apologizes for having gotten Matt killed.

Later in the manga, a TV broadcast reports that his identity is unknown, and that the bodyguards were forced to shoot because he was showing a dangerous and aggressive behavior.
