I bet you were expecting that I would create at least 1 OC for my personal all-time favorite movie. I made two OCs for it, though I don't have a persona for it because I don't know if I would make them a human or a robot. 

D-J is a DJ bot who was built to entertain passengers aboard the Axiom. He has turquoise LED eyes, which are the same color of the "mouth" just above the rod that connects his main structure to his turntables. D-J is one of the only robots on the ship that can speak in full sentences, so said "mouth" moves when he talks and sings. There are light orange sound bars on the sides of his "headphones" that move along to the beat of the music he plays. His "arms" are magnetically drawn to the sides of his "mouth." They stick there whenever he is inactive.

D-J units can be programmed to say anything you need them to, but having achieved sentience, this defective unit in particular can talk on his own. Often, he randomly points out his observations, like his observations of what others are up to. He is great at interacting with an audience and with whoever he wants to talk to. D-J relies on engaging stimuli to stay happy. If the atmosphere around him is too boring or dull, he'll be able to liven up the place. Usually, D-J will not know what's going on unless he is informed of it. He has a very open attitude. 

D-J units were built to provide entertainment whenever it is needed. They are most often seen in the ship's nightclub, but they can also entertain you right in your cabin. They are sometimes used in the all-day care center, playing nursery music to help the babies sleep well. If they need to, they will play music for a funeral. A D-J unit would definitely provide music for WALL-E and EVE's wedding, if they had one.

The D-J bots have two different ways of playing music. Place a CD on their turntables, and they'll play the music on that CD for you. You can also listen to the radio by turning it on on the back of their heads. 

You cannot do both of these things at once. That could break them. 

 As an addition to their musical and verbal capabilities, D-Js are able to sing. When two or more of them sing together, they can create beautiful harmonies unless one of them isn't tuned right. Yep, they work like musical instruments; when they were first built, they had to be tuned. Defective D-J can't sing well, and he doesn't know why. 

D-J goes about his own business much of the time, but he sometimes hangs around with the reject bots, M-O, EVE and WALL-E. He considers all of them to be fun friends, and he is a huge fan of WALL-E and EVE as a couple. These robots have welcomed him into their little friend group. 

For his voice claim, I had two options, and I couldn't decide which was better. The links are right down there in the comments.
