In the floating Park Dome, the park members, Eileen, Anna and Earl are at the playing field. "Congratulations to Pops and (Y/n)! They have officially completed their training! More than an army's work of strength is contained within these vessels." Earl said. Pops is feeding a peacock. "Yum, yum, yum, yum, yum, yum, yum." Pops said. (Y/n) sweat drops. "If you say so..." she said. "Was the peacock the last of your training, Pops?" Mordecai asked. "Uh, no. This is just a weird thing he wanted to do." Earl said, and (Y/n) chuckles. "That's Pops for ya." She said. "But they look exactly the same. Are you trying to tell us that somehow they've changed inside, even though they haven't changed at all on the outside?" Rigby asked.

"Take a shot if you don't believe me." Earl said. "No, no." said. Mordecai said. "We're good." Rigby said. "Come on! You two have destructive tendencies. I know you do." Earl said. "Ain't that the truth." (Y/n) joked, and they glare at her playfully. "Okay, fine." Mordecai said. "Pull my arm." They get off the bench and Rigby attempts to hose (Y/n), but she uses cryokinesis to freeze the water, which amazes everyone. (Y/n) then uses her paw to crush the ice into snow. "Whoa, so cool! Snow cool!" Mordecai said. "Is that all you've got? Come on, really try to take her down." Mordecai runs to catch (Y/n), but she uses her teleportation to avoid it. "Everybody!" Earl shouted. "Uh.." They said. Muscle Man grabs a rock and throws it at Pops, but he turns it into a dove as it flies away.

"Good job, Muscle Man." Fives said. "Hoh, hoh. Way to go, Muscle Man." Skips said. "It turned into a bird." Pops laughs as he lifts Rigby into the air and made pillows appear to drop Rigby on, then Rigby attempts to grab (Y/n), but she makes a wall made out of positive energy. "What?! How'd she do that?!" Rigby asked. "She made a protective wall out of positive energy, and that's not all she can do." Earl said. "Seriously?" Anna asked. "What else can there possibly be?" Rigby asked. "Well, I guess you could say I have a way with words."

Pops said telepathically, then winks and gives him a thumbs up. Rigby screams. "Pops scaled my mind fence!" He shouted. "Yes. Now that they are telepathic, they'll never need a telephone again." Earl said. Eileen clears her throat. "Question." She said. "Same. Actually, I've got more like several questions." Anna said. "Ah, ah, ah. Any questions will be addressed at tonight's formal presentation." Earl said. Later, everyone is in the control room, where Earl hosts the presentation. "The final battle against Anti-Pops and Anti- (Y/n). Now, Planet Nielsen, home of the all-knowing seer that can tell us exactly when, where, and how Pops and (Y/n) will fight the Antis. So we just need to find her." Earl pauses. "That's it. That's the whole presentation." He said. "Ahem. Earl." Pops began.

"What is it?" He asked. "Remember how I said before that I didn't want to fight my brother?" Pops asked. "Yes, but then we did all that training, and now you are ready." Earl said. "Yes, but I still don't want to fight him." Pops said. "Yeah... I still don't want to fight Anti-(Y/n) either." (Y/n) said uncomfortably. "Yeah, but you're gonna." Muscle Man said. "You have to, guys." Fives said. Everyone starts clamoring. "We're all counting on you, guys!" Elieen said. "You have to!" Muscle Man said. "You can do it, guys!" Anna said. "Oh, but certainly there must be some way to end this dispute peacefully." Pops said.

"No, Pops, we've been over this! The scroll says you two fight, so you will fight!" Earl said. "Okay." Pops said, and (Y/n) sighs. "Uh, okay. I guess, uh, let's start plotting the course to Planet Nielsen." Benson said. Everyone leaves. "All right, let's do this." Muscle Man said. "Yep, let's get 'er done." Rigby said. "I'll make coffee." Skips said. "Guess we better buckle up." Later, Pops and (Y/n) are walking alone together. "Oh. There must be a way to reason with the Antis. If only we could get in touch with them." Pops said. "I don't know Pops, are you sure that's a good idea?" (Y/n) asked. "It's better than fighting them, don't you agree?" Pops asked. "Well... I guess." (Y/n) said. "And I know a way we can contact them!" Pops said. Later, Pops is sitting on a rock, meditating to enter Anti-Pops' mind, and Anti-Pops is typing on his computer with a whispering voice saying "Sadness."

"Impossible parking. Had to wait for the bathroom. No free refills! The only reason I'm leaving a one-star rating is that there isn't an option for zero-st-" he sees Pops. "Huh? Pops? You scaled my mind fence?!" He asked. "Don't worry. This is just a friendly visit. I thought I'd "pops" into the old anti-thought attic." Pops giggles. "How dare you show up in my head!" Anti-Pops shouted. "Well, that's just it. I only wanted a chance to get to know my brother a little better. I had no idea you were so sad." Pops said. "You only think that because happy for me feels like sad to you. Like how you see blue where I see orange, but you learned to call your version of blue "orange." Anti-Pops said. "It doesn't have to be this way.

We could become friends." Pops said. "And then what?" Anti-Pops asked. "The joy of friendship lasts forever." Pops said. Anti-Pops smirks evilly. "Yes, perhaps we should meet up and talk this through. I'll host. And be sure to bring (Y/n)." He said. "Oh, of course." Pops said. "Meet me tomorrow in my underground dungeon on the sulfuric-lava planet." Anti-Pops said. "Oh, uh... how about a public place instead?" Pops asked. "Okay. Uh, I know another spot that might work. Do you have a pencil and paper handy?" Anti-Pops said. "I think my supermind should be able to remember it." Pops said. "Yes, of course." Anti-Pops cackles.

In the control room, (Y/n) and the guys are talking when Pops enters. "Everyone, splendid news! There's no need to fight Anti-Pops." Pops said. "Um, how did you arrive at this conclusion, Pops?" Elieen asked. "I telepathically got in touch with him and made a plan to meet in person and figure out how to make peace. Although, he wants me to bring (Y/n)." Pops said. "Pops, you have to know that it's a trap!" (Y/n) said frantically. "I agree. There's no making peace with pure evil." Earl said. "But he's not pure evil." Pops said. "No, Pops! You and (Y/n) will fight the Antis, and that is final!" Earl shouted. "Okay." Pops leaves the control room as Mordecai and Rigby look at each other sadly, then look over to (Y/n) who seemed just as down. Pops is holding two eggs with two faces of the two brothers drawn on it.

Pops imitates Anti-Pops. "Peace sounds like a wonderful idea to me, Pops." Then he speaks in his own voice. "I'm so glad you agree." He starts playing with the eggs. "La, la, la, la, la, la, la. La, la, la, la, la, la, la..." he breaks the eggs in half, holding two egg shells, with the left side being Pops' drawn face and the right side is Anti-Pops'. "Ohh." He whimpers and groans as he starts stirring the batter and turns to see Mordecai and Rigby standing in the doorway. "Ah, Mordecai and Rigby! How long have you been here?" He asked. "A while." Mordecai said.

"I know you all believe that the," Pops puts down the batter. "Only way to save the universe is by destroying Anti-Pops and Anti-(Y/n). But I have never known violence to be an answer before, and I don't see why it should be now." Pops said. "Yeah, we hear you, Pops. It's just, well, this situation's like a video game. Some bad guys can't be beaten with words. In fact, most can't. You beat bad guys by jumping on their heads or punching them in the gut." Rigby said. "Do you?" Pops asked. "Yeah." Rigby said. "And we'll be with you and (Y/n) every step of the way." Mordecai said. "That means a lot to me." Pops said. "Of course." Rigby points to the batter. "Are you still gonna bake that cake?" He asked. "Oh. I suppose." Pops said. "That means a lot to me." Rigby said.

THE NEXT MORNING

Rigby raps as he's oming down the stairs and heading towards the kitchen. "Breakfast cake, cake, cake, cake, ca-cake, ca-ca-ca-cake, ca-ca-ca-cake, ca-ca-ca-ca-ca-ca-cake!" He finds his friends, except Pops, in the kitchen, looking worried. "Where's cake?" He asked. "With Pops and (Y/n)." Anna said. "Where are Pops and (Y/n)?" Rigby asked. "Pops left a note." Skips hands the note to Rigby. "Dear friends, (Y/n) and I have gone to see my evil brother. Cake fixes everything. You'll see. Sincerely, Pops." Rigby read. "They're going to get themselves killed." Muscle Man said. "Themselves and and us-self!" Fives said. "We gotta go find them." Skips said. At a public arcade on an asteroid, Pops and (Y/n) enter with a cake as he sees different aliens playing games and start looking around for Anti-Pops.

They come around the corner and see Anti-Pops, which surprises him. "Hello, Pops and (Y/n). I'm so glad you came. Alone, I presume?" Anti-Pops asked. "As you suspiciously insisted, yes. There's no disagreement so terrible that it can't be hashed out over a good, honest chat, gentleman to gentleman." Pops said. "Very well. I've secured a quiet place to talk. Right this way." He said. "Good show. Good show." They walk down a hall with a door reading "No Admittance" "Oh, dear. This appears to be off..." Anti-Pops opens the door with his telekinesia. "Limits. Well, it is quiet." They enter a closet as Anti-Pops' darkness covers the light.

"This is my kind of place. Really sets the mood." Pops sees a broken arcade game. "Agree?" Anti-Pops said. "It sets a mood, I suppose. We brought you a gift. A man with a tummy full of cake has no need to destroy the universe. That's what I always say." Pops said. "For me? Well, uh, I suppose one taste couldn't hurt." Anti-Pops places his finger on top of the cake and draws a line between the picture of themselves as he scoops up the frosting and tastes it. "Oh, Pops, this cake..." Pops smiles eagerly. "This cake is... TOTAL GARBAGE!!!" He slams the cake to the floor, and (Y/n) gasps. "Oh, my "better together" cake!

You know, I'm starting to wonder if you were ever serious about making peace." Pops said. "Of course I wasn't, you idiot! Why would I want peace for this universe? This place and its creatures offer me nothing, and I plan to extend the favor by destroying it all! The only reason I agreed to this silly meetup was to get my hands on (Y/n)! Then I can finally get Anti-(Y/n) off my back!"

Anti-Pops shouted furiously. "My goodness! I've never met someone who needed a hug so badly." Pops said. "What?!" Pops attempts to hug him, but he blocks him. "Ugh! I don't need a hug!" He shoves Pops. "Pops!" (Y/n) shouted. "Oh, dear." Pops and (Y/n) attempt to escape, but Anti-Pops uses his telekinesis to lift a broken arcade game and block the door with it. He then summons a black hand to grab Pops and (Y/n) and sends Pops to the wall as he falls to the floor, while still holding (Y/n), who struggles in his grip to no avail. "Let me go!" She shouted. "Silence!

"Goodbye, Pops." Anti-Pops summons a giant black hand to crush Pops. "NO!" (Y/n) shouted, but Pops summons a shield to avoid it. "Please, we don't have to do this!" Pops shouted. "Have to?! This is all I want!" The black hand turns into a snake head. "Everything is broken, Pops, just like these games. But I have the solution for broken things." Anti-Pops erases an arcade game from existence as Pops gasps. "See? All better." Anti-Pops said. "How is that better?! All you did was erase it!" (Y/n) shouted. "I agree! That is not better!" Pops bursts out of his shield, dissolving the snake head and regenerates an arcade game called "Save the Universe" with his positive energy. "You see, positive energy can fix so much, even a sad heart like yours."

Pops said. "It's like you don't understand me at all!" Anti-Pops uses his telekinesis to throw a broken arcade game towards Pops, but he misses and he tries to blast Pops, but he misses, creating a hole in the wall as Pops ducks behind another broken arcade game. "You can't hide from me!" He erases another arcade game from existence as Pops tries to save (Y/n), but Anti-Pops' erasing beam erases all the games and he disappears telepathically and reappears as Anti-Pops gets near him. (Y/n) wanted to help, but couldn't since she was being held by Anti-Pops. "I'm tired of looking at you, Pops. JUST... GO... AWAY!!!" Anti-Pops blasts Pops, but he blocks it with his positive energy shield. Anti-Pops then summons a spiked wrecking ball, twirls it and hits Pops' shield, sending him flying to the exit door.

"I guess my friends were right. Some bad guys can't be beaten with words!" Pops flies towards Anti-Pops and prepares to punch him, but Anti-Pops grabs his hand. "Tisk, tisk. Violence doesn't suit you!" Anti-Pops punches Pops to a corner. "POPS!" (Y/n) shouted. "Does it hurt, Pops?" Anti-Pops grabs him by the shirt. "Don't worry, I'll make it all better." He said. He almost gets erased, and Anti-Pops grins evilly. "NO!" (Y/n) shouted.

An an arcade game gets thrown at him as he gets it off him. Muscle Man appears and tries to fight him, but he kicks him off. (Y/n) was dropped to the ground once the arcade game was thrown. Mordecai, Rigby, Fives and Benson charge towards Anti-Pops to fight him while Skips comes to Pops' and (Y/n)'s aid. Anti-Pops laughs evilly as he prepares the final blow to erase him from existence. "Pops, (Y/n), are you okay?!" Skips asked.

He picks him up as everyone else tries to fight Anti-Pops off, but he is no match for them. "Run!" Benson shouted. They run out of the closet and into the arcade. "Where's the exit?!" Muscle Man asked. Anti-Pops' telekinesis beam bursts out as he comes out, and Pops gets thrown to the ground. A slug alien gets erased from existence by Anti-Pops, then he prepares to erase Mordecai and Rigby,

but Earl blasts him with his blue beam. "Fulfill your destiny, Pops, (Y/n). Get him and (Y/n) to the rendezvous point! I'll hold off Anti-Pops!" Earl jumps and pounces on Anti-Pops to fight him. "You heard him, let's go!" Skips grabs Pops and the (Y/n) and the guys make a run for it, but Earl gets beaten and Anti-Pops erases him from existence, followed by the arcade as Anti-Pops' erasing beam starts spreading on the asteroid and the guys are still running towards the Park Dome.

Mordecai pants. "Eileen, open the hatch!" He shouted. In the control room, Skips lays Pops down on a blanket. "We have to get him medical attention." Benson said. Anna sees the erasing beam heading towards the dome. "Guys, we're running out of asteroid fast!" She shouted. "Set coordinates for Planet Nielsen!" Benson said. Eileen presses the launch button as the dome takes off, and the erasing beam completely erases the asteroid from existence.
