The Source is an alien being consisted of a substance called "newfu", which is similar to tofu. He appeared on Earth operating behind a fast-food restaurant called Mega Meaty Meat, using remote-controlled UFO saucers to steal cows and use them as a power source for his planet-destroying device. Beast Boy discovered this when he was working as the only counter help at Mega Meaty Meat in order to win a powerful moped, finding out that his manager Bob was actually a created being made of "newfu", which was what all food products served at the restaurant were made of. Beast Boy kidnapped the Source and threatened him by putting him on a dinner plate and pouring barbecue sauce on him into telling the Teen Titan how to defeat the Bobs and shut down the UFOs and the Earth-destroying device. Later on, when that plan was accomplished, Cyborg was found devouring The Source.
The Source proves that he was still alive while the Teen Titans were attempting to unmask Red X. One of the faces that pops out of Red X's costume is the Source who begins to rant about world domination. Beast Boy quickly eats the villain, and his death is assumed once more. 
- Transformation: When connected to his machines, the Source can generate human figures that are made of the same substance as he is.
