|“||Why do you always decide what's important?||„|
|~ Greg asking|
|“||Because I'm your manager, and you're just some spaced out kid. I'm taking you to the city, and you're gonna play, and you're gonna like it. Maybe you'll even make me some money for once...||„|
|~ Marty's response.|
Marty is a character in Steven Universe who first appeared in "Story for Steven" as the main antagonist. He was formerly Greg Universe's manager until Greg abandoned him, prefering to stay in Beach City to be with Rose Quartz. Marty is Sour Cream's father and the ex-lover of Vidalia.
He is voiced by Jon Wurster.
Story for StevenMarty first appeared in a photo of him and Greg together. Steven asked what happened to Marty and Greg replies saying that Marty "is dead to him". Greg told to Steven that he considered Marty a friend for him, but what Greg didn't realize is that Marty was just using him for his greed all this time to get more money, taking 75% of the profits of each concert they went. Marty also never cared about his position as manager of Greg, as he instead of helping Greg with the merchandise, Marty always wanted to hang out with Vidalia in Greg's van. Marty even insulted Greg when he committed a simple error and always contratdicted Greg's words. Then, when Greg wanted to stay with Rose, Marty taunted him saying that he could have more girls than a "one huge woman". While they discussed, a truck almost hit them but Marty achieved to turn the van. Greg finally asks why Marty is who takes the decisions and Marty tells him that it's because he is his manager and as such, he will take Greg to another city to force him to sing and he will like it. Furious for how Marty treated him all the time, Greg yells at Marty ordering him to get out of the van, but when Marty denied in doing so, Greg kicks Marty from his van leaving him in the road. When the flashback ended, Steven holds the photo of him and Greg saying that he was the worst, however, Greg also thanks Marty because if it wasn't for him, he never could meet Rose. He is last seen in the episode when Greg puts the photo of him and Marty together.
Drop Beat Dad
In this episode, it is revealed that Marty is actually Sour Cream's father, meaning that he impregnated Vidalia some time before he left Beach City. In the beginning of the episode, he returns to Beach City for unknown reasons and reunites with his son Sour Cream, who had been fighting with his stepfather Yellow Tail. Marty and Greg also meet up again, however, they both settle their conflict, encouraging Steven to give up his hatred of Marty. Marty immediately supports Sour Cream's musical career and offers to help him set up a concert, although Yellow Tail is suspicious of his motives and doesn't want his stepson to hang around the man who abandoned his mother. At the concert, it's revealed that Marty just wanted to promote the Guacola soda brand because he had a marketing deal with the company, much to the dismay of Sour Cream. As everyone is disgusted by the undrinkable soda, Sour Cream snaps at his father, tells him off and puts on a real concert. Before he leaves, Marty informs Greg that he came to Beach City because he had to give him a check for 10, 000, 000 dollars, because, as revealed in the next episode, he used one of his songs to advertise a burger restaurant and that he would most likely be sued if he didn't give Greg the money he earned. He leaves afterwards.
- There is a theory which says that Marty and Vidalia could be Sour Cream and Onion's parents, which turned out to be true.
- He has some similarities with Dick Hardly from The Powerpuff Girls.
- Both had a friend which was the father of the heroes (Marty to Greg and Dick to Utonium),
- Both (Greg and Utonium) realized about their friends true intentions and nature and ordered to them to leave their properties (Dick from Utonium's house and Marty from Greg's van).
- Both are blonde, malicious, liars and never cared about the feelings of their friends.
- However unlike Dick Hardly, Marty was just a typical jerk and did not seek to kill or harm Greg in any way.
