Alien

Alien (宇宙人, Uchūjin) is an alien who is looking for his comrades, coins that got spread after a crash. Upon bringing a coin to him, he will grant any wish.

Appearance
Alien is an alien from space, who usually takes the form of a young man with short light brown hair and gray eyes.

Plot
When their planet got polluted, they went traveling in space until it was cleansed, but their ship broke down and crashed on Earth. Since then, the Alien was trying to collect the spread coins, which were his comrades, the aliens had no physical form and had turned themselves into a compressed data, the coins. Once they go somewhere, they would transform into the ideal form for that planet.

Clair came to the Alien with Shuichi, who had his head ripped out and asked him to fix him, but the Alien only got interested after she showed him a coin. Using the coin, he made a "medicine", a nano-technology that fixed Shuichi. To prove himself being an alien, he transformed into Clair after taking some of her DNA. He then explained how he ended up on Earth and how he tries to gather his comrades.

Power & Abilities
Alien's primary ability appears to be shapeshifting which is achieved by collecting the DNA of the intended target. His current form is based on the DNA found on a mattress in the area he resides. He is also shown transforming into Claire. Alien also use this ability to transfer others an act he calls "Granting Wishes". The exact method of this is currently unknown.

While not shown in combat Alien is shown to have a Monster Form that he takes briefly when confronted during the flashback. This form is similar to Tadanori's monster form being tall, black in color, and having what appear to be blades for arms.

Trivia

 * The crash of his spaceship and scattering of his friends is contradicted by his own statements, as there is no plausible way for him to have piloted/controlled his spaceship if he had no physical form. So the real reason for him being on Earth remains a mystery.
