The episode begins with Gumball and Darwin walking around the neighborhood in Elmore, discussing how Rob, in spite of previously declaring them as sworn enemies, failed to follow up on his threats. While this is happening, however, they neglect to notice Rob's repeated, failed attempts to annihilate them. Rob cracks, confronts the pair and tells them that he has given up on trying to get revenge. Unfortunately for Rob, Gumball and Darwin refuse to let him give up, proceeding to follow him around throughout the day. After hitching a ride on a bus and tagging along at the grocery store, Gumball decides that what he needs is a villainous name, causing him and Darwin to bombard Rob with ideas. Rob becomes so irritated that he snaps and destroys his groceries, though it was not in vain, and Gumball finally proposes the perfect new name: Dr. Wrecker.
Gumball and Darwin decide to take Rob home to help work on his voice, eventually modifying it to sound deep and British. Next, they assemble an outfit for him, which he begrudgingly accepts. The two swell up with pride as they watch him practice his evil laugh and decide to throw him a celebration, announcing their intent to join him as his minions. However, he gets incredibly offended by the gesture and storms off.
Rob returns late at night to inform Gumball and Darwin of his plan to wreck the Elmore Dam and flood the whole town. The pair arrive with him at the site of the crime and try to fix the issue by means of cutting wires in a mere 30 seconds, but all hope seems lost. As the timer strikes one, however, instead of the dam bursting as expected, a soda can flies out and hits Gumball in the head. Gumball investigates, only to find that the wires were actually connected to a vending machine, let alone the fact that there was not actually an Elmore Dam in the first place. (It was actually the Elmore Auto Damage Repair Center, though its sign was partially obstructed.)
The three walk home sulking, with Rob clearly depressed by his botched plan. En route, however, Gumball and Darwin spot a trap that Rob had set up earlier, deliberately getting caught in it to raise his spirits. The episode ends with Rob laughing manically at the trap's success and walking off, leaving the two stuck hanging upside-down as they make pleas for help.
The way that Rob puts on his Dr. Wrecker outfit may be a reference to some Japanese tokusatsu shows, like Super Sentai (better known as Power Rangers in America).
During the part in Rob's flashback of an attempt to destroy the metal door to Elmore Dam's control room using a wrecking ball (while riding on it), his pose could be a reference to the 2013 music video "Wrecking Ball" by Miley Cyrus.
At the beginning of the episode, Patrick is cutting grass at a house different from his own.
When Gumball and Darwin scream before Rob's countdown, only Gumball can be heard.
When Rob is sliding down the hill covered with oil, he is missing his static.
The sleeves of Alison’s dress are green but usually they are black.
During the time lapse, the Sausage Dog is abnormally larger.
Gumball: Going for a Sunday walk, there's no payoff! It's like having superpowers but no nemesis to fight.
Darwin: Is walking a superpower?
Gumball: If having fun is your nemesis, then yes.
Darwin: Speaking of nemesis, what happened to that weird-looking guy who swore to be our mortal enemy?
Gumball: Yeah, he was all like, [Evil voice] "I will be your worst nightmare, I will be the terror of your existence, blah blah blah, threatening things, I WILL BE... YOUR ARCHENEMY." [Normally] Cut to: nothing happens.
[As Gumball and Darwin walk away, Rob appears behind them and puts a treadmill down. He takes out a car battery and attempts to slingshot it at them.]
Gumball: I mean that's the problem with kids these days, [Just as the car battery is about to reach Darwin, it flings back and hits Rob on the head] they just don't commit to anything. You know who I blame? Overencouraging parents, medals for participation, and schools with no grades.
[Rob attempts to cut down a telephone pole. As Gumball and Darwin walk closer, he rapidly chops the telephone pole.]
Gumball: And as soon as they fail, they just give up. We can't call them losers [Makes an adorable face] because they tried!
[Rob finishes chopping the pole, only for it to be suspended by the wires. He notices Gumball and Darwin, then jumps in a nearby bush.]
Gumball: And you know what else I blame? College degrees in graphic design and like, mime. Heh, that's what the world needs. More street artists who can use Shotofop.
[Rob tries to launch the pole at Gumball and Darwin, but it hits a tree which falls right onto him.]
Gumball: I have two words for you: MILITARY KINDERGARTEN!
[Rob spills oil on the road and pushes a car down the slope. He cheers but slips.]
Gumball: Something has to be done about it!
Darwin: Dude, chill out! Just breathe.
[Gumball and Darwin take a deep breath and close their eyes. The car takes them to the other side of the road while Rob slides offscreen.]
Gumball: So, no, we won't see our nemesis again. Probably got into a new fad like being a blogger, riding a penny board or whatever.
Rob: [Walks up to them] I'm trying, man, I'm trying to be your enemy!
Darwin: Oh, hi, good to see you!
Rob: It's not supposed to be good to see me!
Darwin: Aw, somebody needs a hug! [He hugs Rob but the oil makes him slide away]
Gumball: What was that?
Rob: It's the oil from the trap.
Darwin: What trap?
Rob: Just one of the five hundred and sixty-three traps I set for you guys! Like this one. [Shows a rope attached to a nearby tree] Look, I don't think I’m capable. Just forget about me. Like everyone else has. [He starts walking but the oil makes him walk on the spot] Would you mind?
Darwin: [Pushes Rob] Should we go...?
Gumball: Yeah, alright. [Starts walking away]
Darwin: No! I mean go after...
Gumball: Yeah, I know. I was just messing with ya.
Darwin: Dude, come back!
Gumball: We'll help you become so evil that you'll grow a goatee!
[Gumball and Darwin go after Rob. A bit later, they're seen riding the bus.]
In The Bus
Gumball: [Whispers] It's really sad that our nemesis rides the bus.
Rob: I can hear you.
Gumball: Yeah, well, I hoped you'd be nutty enough to ride around on a bike made out of human bones, but here you are taking the bus. Not even as scary as that weird cat lady! [To Alison] No offense.
Alison: Don't listen to them, Martin, I know you're a real boy. [The cat meows angrily and scratches her face]
Darwin: Maybe he would look more evil if he had an ominous theme tune.
Gumball: Dude, what's your name?
Gumball and Darwin: [Singing]Bob bob. Bada ba bob. Bob bob bob bob bob bob bob bob, bob bob bob bob bob bob bob bob, BADA BOB!
Rob: It's Rob!
Gumball and Darwin: [Singing]Rob rob rob rob rob rob...
Alison: I would have gone for something more like: [Singing]Robitous! Ominous! At the bus! Robitous ominous at the bus!
Marvin: No, what about: [Imitates a theremin]
Sussie: Eh, what about: [Does little noises then one single loud bass beat]
[Everyone on the bus continue making noises, much to Rob's chagrin. The bus stop by at the parking lot of the mall.]
[Rob leaves in a huff at the mall.]
Gumball: Rob! Dude, Rob! Rob! Rob, come back! Rob! [He and Darwin follow Rob entering the mall.]
In The Mall
[Cut to inside the mall, where Rob is seen sniffling some melons. Gumball gasps]
Gumball: That's it! That's what he’s missing!
Gumball: No, he needs a villainous name like, "Dr. something."
Darwin: Dr. Fruity?
Darwin: Dr. Dandruff?
Gumball: Dr. Ethically-sourced-tuna-fish!
Darwin: Dr. Jerky!
Gumball: Dr. Moisturizer!
Darwin: Dr. Old-man-reaching-for-a-jar-of-olives?
Old man: Yes?
Darwin: Never mind...
Gumball: Come on, man, give us something to work with.
Darwin: How about Dr. Fuzz?
Gumball: Yeah, or Dr. [Imitates static]
Darwin: It’s more like Dr. [Imitates static]
[Gumball and Darwin keep making noises resembling static until Rob throws his groceries on the floor and stomps on them, screaming.]
Gumball: [Takes a really deep breath]
Rob: Are you ok?
Gumball: Just having a eureka moment. What about... [Evil voice] Dr. Wrecker!
Rob: I! I... I like it. [Says in a squeaky voice:] Dr. Wrecker!
Gumball: We're gonna have to work on the voice.
[Cut to the Wattersons' house. Gumball, Darwin and Rob are in the living room.]
Gumball: Ok, try the british accent again.
Rob: [Slightly high-pitched, rolling 'r's] I will destroy yee and everyone yee love.
Gumball: Eh, sounds like a cat being strangled by another cat who's also being strangled. Underwater. Ok, hold on. [Grabs a remote and aims it at Rob, going through different menus] No no, color, no... Sharpness? No... Subtitles, nah... Ah, there! [Changes setting to "English"] Try again.
Rob: [High-pitched] I will destroy you and everyone you love.
Gumball: Hold on, I need to adjust the bass. [Presses a button on the remote] Ok, again.
Rob: [High-pitched, so loud the house shakes] I will destroy you-
Gumball: Sorry, sorry! That was the volume! Ok. [Presses another button] Again?
Rob: [In a deep voice] I will destroy you and everyone you love!
Gumball and Darwin: [Gasp in admiration]
Rob: I am Dr. Wrecker, kneel before Dr. Wrecker, Dr. Wrecker is-
Gumball: [Mutes Rob] Ok, calm down. Next we need to get you an outfit.
[A sequence shows different pieces of armor appearing on Rob. It is interrupted by Gumball throwing a cardboard helmet at Rob, who is standing on the chair in Gumball and Darwin's room.]
Rob: Ow! This is ridiculous, why do I have to get dressed like this?
Gumball: Because you don't see villains spending ten minutes hopping on one foot, pushing their leg through their armored pants! Come on, lower your head. [Throws helmet again] Maybe you just put the helmet on yourself.
Rob: [Puts on helmet] I am Dr. Wrecker! Oh oh oh! No, that's not right. Ha, ha, ha! No no no, still not right. Ha ha ha ha! No, that's not good.
Darwin: Our evil baby's almost ready to go out into the big, wide world.
Gumball: And destroy it.
Darwin: This calls for a celebration! [Gumball and Darwin crawl out of the room]
Rob: Ah ah ah! [Goes downstairs] Ha ha ha! How did that sound? Guys? Guys! Hello?
Darwin and Gumball: [Blow party horns] Happy evil day, master!
[The room is decorated with birthday supplies with skulls drawn over them and a "HAPPY EVIL DAY" banner. Rob takes a Daisy the Donkey paper plate.]
Gumball: I'm sorry, master. It was kind of hard to buy evil stuff online without ticking a box saying I was eighteen, so we had to improvise.
Rob: What is all this?
Darwin: We've had so much fun, we'd rather be your minions than your enemies. A cookie for the master? [Hands a plate of skull-shaped cookies to Rob]
Rob: You think this is a game? You think that because you helped me find myself, I'm no longer your enemy? You think we’re friends? I am Dr. Wrecker and before long, you will be wreck-tified!
Darwin: What does that mean?
Gumball: Doesn't really make sense.
Rob: Yes, I'm not 100% on the catchphrase yet. But this is what I do to your friendship! [Throws the cookie plate and stomps it]
Darwin: [Tears up]
Rob: Mark my words: I will destroy you and everyone you love! [Slams the front door as he leaves]
Gumball: Who would’ve thought in creating a monster, we'd create a monster?
[At nighttime, Gumball is trying to comfort Darwin when the doorbell rings. They open the door.]
Gumball: Oh, our little "friend" has come back to play.
Rob: I'm afraid it has become a little more serious than that. I set in process a series of events so magnificent in their conception that it will destroy-
Rob: -that it will wreck the whole of Elmore and everyone in it, but mostly you. And where better to wreak maximum damage than the Elmore dam?
[A flashback shows Rob sneaking into a closed area, where a sign reads "Elmore Dam."]
Rob: I knew if I wrecked the control room, the whole town would flood. [Knocks on a metal door] A door like this would present a problem to a mere mortal but not to Dr. Wrecker and his wrecking ball! [Rides a wrecking ball]
Gumball: Wait, you hired a wrecking ball?
Rob: You bet! [Breaks the wall beside the door] You just got wrecked!
[The broken wall reveals a control panel with electricity and water coming out of it. The flashback stops.]
Gumball: Stylish entrance, check. Global threat, check. Use of improved catchphrase, "you just got wrecked," check. The final category is getting away in style.
Rob: Ah, well, I was going to escape by bus. [Flashback shows Rob waiting at a bus stop][Whispering to himself] I'm Dr. Wrecker, no no, you just got wrecked. I'm Dr. Wrecker - Then I realized it's Sunday, and the buses stop early on a Sunday.
Darwin: So, you need our help.
Gumball: [Whispers] You never apologized for wrecking his cookies.
Rob: Did I mention the whole town is about to be wrecked? Because who cares about your cookies?!
Darwin: It was more than cookies, you wrecked my feelings, young man!
Gumball: It's one thing being a nemesis, it's another thing entirely being a bully.
Rob: Oh, for the love of- I'm sorry.
Gumball: I think if you were really sorry, you'd give him a hug.
Rob: Are you kidding?! Ah. [Hugs Darwin]
Darwin: Ok, I forgive you.
Gumball: Then let's save the town!
[Rob 'runs' while heroic music plays, but it is quickly revealed he is sitting in a desk chair pushed by Gumball and Darwin.]
Rob: Thanks, guys, you know this outfit pinches when I run.
[Eventually, Gumball, Darwin and Rob make it to the closed area. Electricity sparks out of a control panel exposed by a hole in the wall.]
Rob: Fix it, minions!
Gumball: What do you mean "fix it?" It's ruined.
Darwin: Ok, ok, there should be a blue, a red, and a yellow wire.
Darwin: Cut the yellow wire.
Gumball: Ok. [Prepares to cut the wire with his fingers]
Darwin: No no no, wait!
Darwin: I have no credentials or diploma. It would be criminally stupid to listen to me.
Rob: Hurry up, there's only thirty seconds left. [Looks at watch] I mean twenty-nine. I mean twenty-eight. I mean twenty-seven. I mean twenty-six. I mean - we don't have time to lose! Twenty seconds.
[As Rob counts down, Gumball's hand gets closer and closer to the wires.]
