Rob

Rob is the main antagonist and a supporting character in The Amazing World of Gumball. He was formerly a minor background student at Elmore Junior High and was first seen in a poster of the show posted online. Once the world became aware of his uselessness, he was sent to the Void, escaping by holding onto the back of Janice. In later seasons, he becomes the main antagonist of the show, and Gumball's arch-nemesis.

Appearance
Rob was formerly a tall cyclops with a very slim blue body and a single large eye located in the center of his face with a magenta iris. He has extremely long, skinny limbs, pink hands with visible nails, and an over-sized head. He wears a pair of red short shorts with two light orange stripes on the left side, an orange-sleeved yellow T-shirt crop top, dark orange shoes with blue laces and a brown backpack. He had medium-length auburn hair, which covered a bit of the right side of his eye.

In season 2, he gets a minor redesign. He becomes a 2D character with less detail and his shoes now have yellow buckles rather than blue laces.

After his escape from the Void, Rob's appearance becomes disfigured and broken due to the Void attempting to pull him back in as he clung on to Janice and becomes 3D animated once again. His head is now dodecahedronal and floats slightly above his body, his clothes are now much more polygonal, and parts of his head, his arms and legs periodically display distorted static and glitch in and out, although his midriff inconsistently switches between being pink and static. The right half of his head is now cut off, and the hair that remains has also become polygonal in shape and solid brown in color. Rob's static can be affected by his emotions, as shown when it changes to a darker color as he expresses frustration or malevolence.

His single eye is now pale yellow and his magenta iris is gone, becoming a black pupil, his tongue is now a yellow color, and his eyebrow changed from black to brown and usually, when Rob raises it, the right side clips through his head. Initially, his pupil was a lemniscate shape, though from season 5 onwards, it was changed to a more ovular design.

The skin tone of his head has changed from blue to grey, his left leg and his wrists have pink patches, and his left shoe has been reduced to chartreuse wireframe. His right shoe and hand have changed color to solid dark grey, but his left hand stays the same as before.

He wears the same yellow shirt and red shorts, though the shirt now has a rhombus-shaped hole and its sleeves are missing, the stripes of his shorts are on the right side rather than the left, and his backpack is now a solid hexagon shape and has no straps, floating behind him.

After being painted back into existence after a fight in "The Future," he was given a pink, curly pig tail.

Superintendent Evil
In "The Inquisition," Rob disguises himself as Superintendent Evil, an elderly human male portrayed by Garrick Hagon, wearing a white shirt with a gray suit and tie, along with gray pants and black shoes.

Personality
Rob was formerly a nice, sociable person who would enthusiastically greet any passersby on the street whom he knew. Though in "The Pony," Gumball and Darwin call him the wrong name, make him a hollow promise, and kick him down a manhole, he showed that he can easily forgive by temporarily catching their DVD from the sewers.

After his escape from the Void, he temporarily develops amnesia and becomes somewhat depressed. He lives in the basement of the Wattersons' house until Gumball and Darwin become suspicious of his stolen goods. They eventually track him down, and after cornering him, they force him to explain his actions. When they mention that there really isn't a villain in Elmore, the boys suggest he become their arch-nemesis - a suggestion that triggers his memory. He recounts how he begged the boys for help as they passed him in the Void, and how they ignored him and went for Molly (though they failed to notice him). His villainous backstory set, he swears vengeance on the boys for abandoning him and agrees to become their arch-nemesis.

As a villain, Rob has a very nihilistic philosophy on life. He becomes vengeful and bitter. No longer does he care about the well beings of others, and only cares about getting revenge on his self-sworn nemesis: Gumball. This is evident in "The Bus" when he kidnaps both the students and the adults aboard the bus with plans to blow them up simply because he hates Gumball. Such a philosophy is explored even further in "The Disaster" and "The Rerun," in which he becomes aware of his fictional status and wants to make Gumball's life as miserable and broken as possible for the way he's treated on the show.

Despite this, "The Rerun" does show he has a heart as after Gumball attempts to save him, he sacrifices his friendship with Gumball to return to his villainous lifestyle and undo all of the damage. This attitude changes, however, in "The Ex," when Gumball foils all of his plans to destroy Banana Joe, and at the end of the episode, re-establishes his hatred for Gumball. However, in "The Inquisition," he tried to save everyone he could from a mysterious threat by turning them into humans though unfortunately he failed due to everyone either not listening or believing him.

Quotes
"Did you just call me Rich like it was a question?" "They kicked me down a manhole!" "I clung to life, and I came back. But at a cost. You left me disfigured, a nobody, but now you've given me a part to play in the world." "I'm trying, man, I'm trying to be your enemy!" "I will destroy you and everyone you love!" "Darn auto-correct... stupid thing never works." "You turned me into the villain, Gumball Watterson, you left me with this broken body, you gave me this ridiculous voice! But now, I am in control. And the time has come for you to pay." "That's not even a man's name!" "No, no, no, my name isn't—My name is Rob, gosh darn it!" "Why? This is where my story ends! I belong here with the rest of the universe's mistakes, like socks and sandals, the helicopter ejector seat, and ...whatever that thing is." ""Yeah, I should have let you know. The thing is, I'm neme-seeing someone else now."" "What is wrong with you?! You just ruined the whole thing for me again! I don't believe it! You've got to be the most insufferable, annoying, selfish person I've ever met! In fact, I think I really, really, really ha-a-ate yo-o-u!" "Oh no... it's started."

 * He has the second most major roles (with a total of nine) for a character that is not a Watterson, next to Penny.
 * Rob made a cameo on the computer in "The Genius," and it shows that his friends are (in order) Teri, Alan, Leslie, and Carmen. It also shows him wearing a mustang mask in the desert on Fessebook. This same page reappears in "The Internet."
 * Technically, Rob, Bobert, and Banana Bob have the same name, since they are all shortened forms of the name Robert.
 * An early design of Rob shows him using an arm and hand as a third leg.
 * Originally for season 1, Rob was animated with CGI. In season 2, he was changed to a 2D animated character. In "The Nobody," he is back to being animated in CGI. This makes him, the Evil Turtle's babies, Ocho, and Blitzer the only characters to be animated in both 2D and CGI.

 * Rob spoke in a British accent when he was voiced by David Warner . His British accent was made in "The Nemesis" when Gumball changed Rob's voice. He kept the accent in "The Uploads," "The Bus," "The Love," and "The Disaster;" after that, he reset his voice with the universal remote.
