The episode starts when Gumball defeats a final boss on an arcade game by using a technique called "button-mashing" and he is told to put three letters as a name for the leaderboard. He first proposes "Gum" and "Bal" until Darwin suggests using his real name, trying to find out what it is. Gumball then gives a long speech lasting most of the day about what he will do to identify his real name. Then at the house, Gumball is talking about his real name as Nicole reveals that it's Zach and he, along with Darwin is whispering it in the school bus. Later, Gumball as an alter ego, goes to school to talk about the school basketball team and band, eating Banana Joe's cousin's face, skipping in line in a supermarket and letting Darwin take his place while shoppers throw items at him. When Darwin comes home, he discovers that Anais now has to live in a shoe, Richard is dressed as a woman and not considered a dad but a "male mother" and their mom has lost in a match between Gumball in being the most obnoxious. Later, the family proposes to change his name to Gumball by going to the Town Hall by driving a car at full speed. Darwin and Anais try to tell Gumball to remember his true identity as in his subconscious; his alter ego tries to modify his memories from being a loser to being always a winner. Meanwhile in the real world, Nicole tries to escape from police and at the paintball match dream as seen in "The Fridge," his arcade memory appears and after realizing that his name is Gumball, Zach disintegrates. Gumball wakes up and signs his nickname into the document, and the bureaucrat tells them that they could have used the internet to change Zach's name.
Mike and Gumball return from the antagonist being released.
Mal and Zach personality fade away upon their defeat.
Zach being a real manifestation of Gumball's negative traits but worse is reminiscent of Nega Scott in the Scott Pilgrim Graphic Novels.
Gumball's collar starts' popping to indicate Zach is in control, but Gumball's sweater clearly doesn't have a collar.
There are some errors during Gumball's flashbacks:
In the scene from "The Sweaters," Carlton and Troy's positions on the court switch with Gumball's, Carlton and Troy's tennis racquets are gone, and Darwin is not present.
In the scene from "The Fridge," Zach holds the flag, standing on a rock, but in the actual episode, the flag is on a hill. Also, Zach's paint-gun had pink paint, where Gumball's paint-gun had blue paint.
In the scene from "The Curse," Gumball was shown in his Season 1 design, but when Zach alters the memory, he is in his Season 2 design.
When the Wattersons were in the car, Gumball's tail was seen on his right leg, which could have been misplaced or longer.
Darwin's right sock was dark blue when Gumball was button mashing.
When Gumball and Darwin were walking home on the sidewalk, Darwin has three eyelashes instead of two. This error also occurs when he is with Carrie.
When Nicole says "By being obnoxious!" her teeth disappear.
[The episode begins with Gumball playing a video game at Funland, and he starts panicking. Darwin attempts to comfort him.]
Darwin: Dude, chill out. It’s only a game!
Gumball: You don’t understand, man. I’ve never got this far before. Look how much I’m sweating.
Darwin: Stop it! You’ll electrocute yourself!
Game: Round complete!
Gumball: Oh, I can’t beat the final boss man! I’m weak.
Darwin: You’re not weak. You just lack upper-body strength, lower-body strength, and mental strength.
Gumball: Slap me. [Darwin slaps him] Harder. [Darwin slaps him again] Ow! Softer. [Darwin rubs Gumball's face] Okay, maybe somewhere in between. [Darwin slaps him once more]
Gumball: That was exactly right.
Darwin: Come on. You can win this by the power of… button mashing!
[Gumball hits all the buttons repeatedly very fast, making him beat the boss easily.]
Game: You win!
Gumball: Dude, what’s the point in learning all these combos if all you need is button mashing?
Darwin: Who cares? Top score!
Gumball: Aw, man. it’s only three letters in the top score. Mm, what do I go with - “GUM” or “BAL”?
Darwin: Maybe go with the least dumb-sounding.
Gumball: You’re right. Let’s go with “BAL.”
Darwin: No. Wait. Why don’t you use your real name instead of your nickname?
Gumball: Great idea! Wait. What is it?
Darwin: What do you mean, “what is it”? What kind of guy doesn’t know his own name?
Gumball: You don’t know it, either, do you?
Gumball: Then this shall be my quest. I will find out that name. I will stop at nothing! I will leave no stone unturned! I will climb the highest mountain, explore every island, search every cave! I will question every man, woman and animal! Fight a bear if I have to! I’ll wear shorts! I’ll milk a fish! I’ll shave a baby!
Darwin: Climb a rainbow!
Gumball: No, that would be ridiculous. But I will lick an owl! I will wrestle a senior citizen in jello!
[Watterson house, Gumball is still speaking]
Gumball: I’ll kick a crab in the face! And I’ll steal a watch from a ghost! I’ll eat a beard! I’ll marinate a plumber! And when they write about me in history books, they will say, “He did what had to be done to find out his real name."
Nicole: Your real name? It’s Zach.
[Elmore School Bus]
Gumball and Darwin: Zach.
Banana Joe: Who’s Zach?
Gumball: I am.
Banana Joe: Oh. [to Jamie]: Gumball’s called "Zach" now.
Banana Joe: Yeah. Good point.
Gumball: Hey, coach, great game last night!
Coach: You’re not on the team, Watterson. [Gumball takes the ball from her and attempts to dribble it, but ends up hitting Juke]
Gumball: Go, Elmore ducks! Whoo-o-o-o-o! [carted away by Darwin] Hey Carrie, I think we really nailed the song last night. We’re totally gonna win the battle of the bands, man.
Carrie: You’re not in a band. I’m not in a band. I bet you can’t even give me the name of a band.
Gumball: Psch, yeah, like… Germany.
Darwin: Whoo! [carts Gumball away]
[At the cafeteria, Gumball skates past the tables and grabs a an apple, taking a bite of it and then tossing it away]
Banana Joe: Hey, that’s my cousin! [Banana Joe's cousin cries]
[At the school courtyard, Jamie and Tina are playing basketball, until Gumball swipes the ball and attempts to shoot it into the basket, but misses and hits a car]
Gumball: Touchdown! Whoo!
[Gumball skates into the school hallway, and kicks his board, which knocks out Mr. Small]
Gumball: Watch out, world! There’s a new cat in town! And he’s called… [slides across the pavement] Zach!
[The school bell rings and students start exiting the school.]
Gumball: School’s over already?
Darwin: Yeah, and you spent the whole day with one eyebrow raised, behaving like a horrible jerk. Are you all right?
Gumball: Oh, Zach is fine.
Darwin: Are you sure?’ Cause Zach is kind of digesting part of an apple kid’s face right now.
Gumball: That’s cause Zach does what he wants.
Darwin: Sorry, but who exactly is this Zach? I thought he’d be like Gumball but with a shorter name.
Gumball: No! Gumball’s a loser. Zach is the man. Zach doesn’t ask. [Licks Sarah] He takes.
Darwin: Ugh! Dude, what are you doing?!
Gumball: Zach doesn’t have to explain himself because he smells so good.
Darwin: Zach, listen to me.
Gumball: Zach doesn’t listen. He hears.
Darwin: That’s the same thing!
Gumball: Oh, wait. What was that? I’m afraid I can’t listen you.
Gumball: Walk with me. See, Zach doesn’t wait for doors to open. He punches right through them.
[Gumball punches the doors, but they open before he hits them. After a while he gets frustrated and stops.]
Gumball: Metaphorically, of course. [enters the store] See, here’s another example. Zach doesn’t waste his time. He goes straight to the point. [Zach starts cutting in line] Make way, losers. I’m more important than you.
[Hank Construction Man stops Zach]
Gumball: You think that’ll stop Zach? Well, Zach is like water. He always finds a way.
Hank: [Zach goes through the man's clothes] Oh! Ah! Ooh!
Darwin: [follows Zach to the front of the line] You do realize you’ve done all this, and you have nothing to buy, right?
Gumball: Yeah, that’s why you’re gonna stay here and hold my place.
Hank: Hey, kid, get in line like everyone else.
Crocodile Woman: You’ve got three seconds to move, or I’ll bingo-wing you.
Marvin: Have you got no respect?!
Hank: Get to the back of the line!
Banana Bob: I’m screaming because they are! [throws objects at Darwin]
Darwin: Dude! Can you say sorry to these people before they get to the heavy items at the bottom of the cart?
Gumball: Zach doesn’t apologize. He uses his charm. Can you pay for this, buddy? Thank you.
Darwin: All right, you lovable rogue. Hey, wait! Where are you going?
Gumball: Zach doesn’t hang out with losers. He lives too fast. [Zach rapidly walks out of the store]
Darwin: No, wait!
[Darwin charges after Zach but gets bingo-winged by Crocodile Woman.]
Crocodile Woman: I warned you.
Zach Must Go
[Back at the Watterson house, an angry Darwin slams the door shut and finds Anais popping out of a boot.]
Darwin: What are you doing? What happened?
Anais: Zach. He said he needed his own “hang space,” so he threw us out of the bedroom. This is where I sleep now...
Darwin: What?! What about me?
[Anais points to the turtle's lair. The turtle laughs evilly, and Darwin whimpers.]
Darwin: How can Mr. Dad let this happen?
[Shows Richard dressed in a skirt with makeup and a handbag]
Richard: I’m not allowed to be called “dad" anymore. Zach made me sign away my position as man of the house. What am I now? Assistant mom? Vice mother? Man mom?
Darwin: Okay... What does Mrs. Mom think of this?
Anais: Ask her yourself.
[Darwin walks to the kitchen and sees Zach poking Nicole repeatedly.]
Darwin: What’s going on?
Nicole: I tried to teach him a lesson by beating him at anything he chose.
Darwin: What did he choose?
Nicole: Being obnoxious!
Gumball: Yeah, I won!
[Zach runs, hops off Darwin's head, and lands on the table]
