His name is Dreams&Disasters (like the Owl City song :p)
But most call him D&D for short
Or double-D

He's also Metro's brother.

He lives in Los Angeles. He is friends with a human, a nightclub DJ named Jack, known as DJ Kiwi.
While Jack works a few nightclubs with Double-D at night, he wants to eventually produce his own actual music. And Double-D helps him to create beats and instrumental melodies for inspiration.

They both live in a crappy third-floor extended-stay hotel room. And Jack works as the maintenance man in the hotel to earn his rent. He earns the rest of his money at the various LA nightclub gigs. And he's saving up to produce his first album.
