In the 1000th anniversary of a hero that defeated Anderous, Anderous escapes & goes after Gumball, because he's a descendent of the hero.
(Starts at 2 logos)
Anderous: 1,000 years ago, I, Anderous, spreaded terror to the world. Until a hero defeated me & named the town Elmore. So every thousands years, I'm able to escape to spread terror again. However, I soon find out that 1 kid is the descendent of my enemy: Gumball Watterson. (Theme Plays) NO, you sicko! Dramatic Music! That's better.
(cuts to school)
Miss Simian: Today is the 1000th anniversary of the founding of Elmore. So, class is dismissed early today. (Everyone starts running)
(Montage of the festival is shown & cuts to nighttime)
Anderous: Get me out of here! NOW!
(Statue breaks & Anderous starts laughing manically, killing Sal in the process)
Anderous: Hello, everyone, I'm back! (Everyone screams) QUIET!!! Which one of you is Gumball Watterson (Gumball pops up) So you're Gumball, huh? I thought you were an adult. The prophecy says only an adult can hurt me. Now let's get it started here. (kills Larry, The Doughnut Sheriff & The Robinsons)
Nicole: Gumball, you're the descendent of the hero, but you can't hurt until you're an adult. (Anderous kills Rocky, Principal Brown, Mr. Small & Miss Simian) (Everyone else runs away)
Anderous: Hey, get back here! (kills Idaho, Anton & Banana Joe)
Anais: What are we going to do?
Nicole: I don't know, but you guys head to the Forest of Doom! (gets killed)
Gumball, Darwin & Anais: MOM!!!!!!!
Penny: Gumball, over here!
Tobias: Follow us! (they all head to the forest of doom & Carrie joins in)
(Anderous fires a blast at the forest of doom)
Penny: Since we're about to die, I wanted to do something with you.
Gumball: What's that?
(they end up kissing)
(Darwin & Carrie do the same)
Anderous: Ew! Gross! (kills everyone) It seems if I have stopped the prophecy, because if it was fulfilled, I'm would be a goner & I'll actually die! Hmm... Now what I'm going to do? (looks through the ruins of everyone's house)
(He finds Bobert)
Bobert: Oh, hi!
Anderous: Hi! Um, since the final battle has adults I'm going to ask you if you get a timecard over here.
Bobert: Sure thing. (Pulls up an intermission card)
(During the intermission)
Anderous: By the way, you need a better voice. Sorry, Kerry Shale, but you're being replaced.
Announcer: The voice of Bobert will now being played by Paul Bettany.
Bobert (now an adult): I sound like JARVIS now.
Anderous: Because the Avengers was great so you needed a better voice actor. (Bobert imprints a JARVIS symbol on him) You've read my mind.
(cuts to Bobert carring Tobias & Rachel's bodies)
Bobert: I'll need this (picks up an aging solution & tears Tobias & Rachel's clothes off) Before I do this, you guys needed better voice actors. Sorry, Hugo Harrison & Grey Delisle, but you're being replaced. (a fog comes out of Tobias and Rachel & another comes in)
Announcer: The voices of Tobias & Rachel will now be played by Troy Baker & Jessica DiCicco.
(Bobert injects them with aging solution & puts a grappling hook on Tobias) (Then he dips Rachel in lava so she could absorb enough) (Finally he brings them back to life)
Tobias: Where are we? And why do sound like Jetfire?
Rachel: And why do I sound like Flame Princess?
Bobert: Long Story. Here put this on. (gives Tobias clothes in the same color as Jazz & Rachel a flame costume) Tobias, That grappling hook will allow to swing, ok? & Rachel, you can control fire because I dipped you in lava.
Bobert: Now lets get Anais. (gets Anais & injects the aging solution) Now for the new voice.
Announcer: The voice of Anais will now be played by Kate Higgins.
(Bobert wires her up & brings her to life)
Anais: Why do I sound like Franke Stein
Bobert (sighs): Long Story. Put this on (gives her Franke's clothing) I wired you up so you can control machine just not me. (kisses her) Now let's get Darwin & Carrie. (They get the 2 & Boberts injects them with an aging solution)
Bobert: I hope this works! (starts stretching Darwin & later upgrades Carrie's teleportation) Now for the voices.
Announcer: The voices of Darwin & Carrie will now be played by John DiMaggio & April Stewart.
(Bobert then brings them to life)
Darwin: Why do I sound like Jake The Dog?
Carrie: And why do I sound like Susan from Regular Show?
Bobert (sighs frustratingly): Long Story! Put this on. (gives Darwin & Carrie battle armor) Darwin, you can now stretch much like Jake & Carrie, I've upgraded your teleportation.
(He then makes them kiss, which they're now used to)
Bobert: Now lets get who we came for! (goes to get Gumball & Penny) (When he digs them up, he hugs thier bodies sadly) This has GOT to work! (injects them with aging solution) Now for the voices.
