Marty

"See, Greg, this is your problem. You want one huge woman when you could have multiple, smaller ones."

Marty is Greg's former manager, before Greg left him and his tour for Rose Quartz. He made his debut in "Story for Steven".

"Story for Steven"
Marty appears as a middle-aged man, with short, platinum/gray/silver hair styled with spikes. He also has slate gray eyes and spiked teeth and wears a dark purple jacket over a navy blue hoodie over an indigo shirt. He also wears greenish-grey pants, black socks, and light brown leather shoes.

"Drop Beat Dad"
Marty appears to have aged significantly, with balding platinum/gray/silver hair styled similar to his first appearance, with a tuff of hair that slightly resembles Onion's hair. He wears a dark brown jacket over a green shirt, with a gold chain necklace. He also wears grey pants, also with another gold chain, and golden shoes with wing-like designs on the sides. He also has a pair of sunglasses similar to the ones worn by Buck Dewey, and has pierced ears with gold studs.

Personality
Marty was shown to be insensitive, uncaring, and selfish, as seen in "Story for Steven", during Greg's concert at Beach City. Rather than managing Greg's merchandise booth like he was supposed to, he was shown hanging out with Vidalia at the back of the van. He was shown to be concerned only about himself and getting what he wants. He made no excuses and didn't try to hide the fact that he is only using Greg to get what he wants; mainly money, women, and fame. This is reflected in the fact that he spent most, if not all, of his time in Beach City with Vidalia and her friends yet he has no qualms about dumping and leaving her behind once the two had to move on with the Mr. Universe tour.

His attitude about using people for his own gain and pleasure was summed up in his reply to Greg when he tells him he wants to stay in Beach City with Rose: "See, Greg, this is your problem: You want one huge woman when you could have multiple smaller ones."

"Story for Steven"
Marty is introduced as Greg's manager and is left on the side of the road near the end of the episode.

"Onion Friend"
Marty is mentioned by Vidalia and Amethyst when they talk about their past. His current state is unknown.

"Drop Beat Dad"
Marty revisits Beach City to advertise Guacola, and is still as manipulative as ever; he tells Sour Cream that he was "making up for lost time" when he "helped" him with his DJ gig. Marty reveals that the whole point of him coming to Beach City was to give Greg and envelope labeled "Star Child" that contained a check for ten million dollars.

Episode Appearances

 * "Story for Steven" (debut)
 * "Onion Friend" (mentioned)
 * "Drop Beat Dad"

Greg Universe
Marty was Greg's manager who was very greedy, taking 75% of the profits. He was also very condescending to Greg, constantly berating and insulting him. He did not even try to hide the fact that he was just using him. At the end of the episode, Greg is finally fed-up with Marty and chooses Rose over him, kicking Marty out of his van.

According to Greg, Marty is "dead to him". He does, however, admit that if it weren't for Marty, he would not have had the chance to meet Rose; so at the end of the episode he puts up a picture of himself and Marty on the shelf in his van that also holds other meaningful photos.

Marty later returns to give Greg a check for 10 million dollars out of legal obligation

Vidalia
Vidalia hooks-up with him as Greg is playing in Beach City. They attended a party with her friends together. Their relationship seems to have not been anything serious but rather a cheap fling, as Marty is quick to abandon her when he and Greg have to leave Beach City to continue the tour—which is a stark contrast to how Greg felt towards Rose. It's confirmed in "Onion Friend" that he is Sour Cream's father.

Sour Cream
Sour Cream is Marty and Vidalia's son possibly conceived when Marty and Vidalia hooked up. He and his mother were later abandoned by Marty.

Sour Cream seems to trust Marty during his return, and eagerly follows his every comand. Later on, when its reveiled that Marty has been using Sour Cream to advertise Guacola in Beach City, Sour Cream yells at him in the same language as Yellowtail and Onion, along with english.

Steven Universe
Steven is seen to have a dislking towards Marty, as seen when he offers to protect Greg from him.
