Where Hyness tries to summon Void Termina, but instead manages to bring Discord (pre-reformation) over to the Kirby-universe. Then Discord decided to fuse the two universes together in order to conquer both.
The 13:th pairing are between another pair of former villians (Sunset Shimmer and Magolor), after they got to know each other.
Magolor: Greetings, I see that you are as confused about this current situation.
Sunset: Yes I am, I was just studying some magic and all of the sudden all this happened. Looks at Magolor Who are you exactly?
Magolor: Oh I am sorry, my name is Magolor. reaches his hand out What is your name?
Sunset: I am Sunset Shimmer. shakes Magolor’s hand Hey, where are your arms?
Magolor: All the people that are born on my home-world Halcandra, don’t have arms. There may be others, but so far I haven’t personally met any of of yet.
Sunset: I must say that you look pretty adorable. hugs him
Magolor: Oh blushes Thank you very much Sunset. You are quite adorable yourself for a… what is your species called?
Sunset: I am a unicorn.
Magolor: A unicorn you say. Well, it is interessting to meet new creatures.
Sunset: So you also like to learn new things? That is great, when all this is over we can become friends if you would like.
Magolor: Friends? looks sad
Sunset: Everything okay?
Magolor: I am not sure if I really understand what it is to be friends with someone else.
Sunset: Huh? Please Magolor, tell me what is wrong?
Magolor: Well, the thing is… I… wasn’t always the best person.
Sunset: Sits down on the ground and comforts him I wasn’t the best person either, most certianly when I tried to take Twilight’s crown and use it to conquer Equestria.
Magolor: You have a connection to a crown as well?
Sunset: Yes, I did. What about you? What did you do that makes you feel so much regret?
Magolor: Sighs Well… I… in my World ther eis an ancient artifact called the “Master Crown” that can grant anyone who wears it an unfathomable about of power. So I used the Lor Starcutter, a built by my ancestors to fight Landia who used to wear the crown. But after suffering a terrible defeat, I was forced to retreat to Planet Popstar. The same world that your world has now been fused with. After crash-landing, I was discovered by four individuals; Kirby, King Dedede, Meta Knight and Waddle Dee. They agreed to help me to repair my ship and I accepted it. Then as they discovered the pieces one-by-one, I came to the realization that I could use them to defeat Landia so I could get the crown. So after my ship was repaired and we returned to Halcandra, we ere attacked again by Landia. Then after defeating her, I revealed my plan and showed my appreciation to them by conquering Planet Popstar. But with the help of Landia, they defeated me and brought Peace back to the universe.
Sunset: Oh dear and I thought I did some horrible things in the past.
Magolor: Well, then what did you do?
Sunset: I acted like a bully towards the students of a highschool, stole the Element of Magic, transformed into a demon, brainwashed all the students at the school and threatened to conquer all of Equestria.
Magolor: With teenagers?
Sunset: nods
Magolor: awkward silence And I suppose you had to build an amusement park in order to get back the respect from the people you took advantage off?
Sunset: No, but it did take a while before the students accepted me as a friend.
Magolor: I am not sure if the amusement park even is enough to earn back Kirby’s friendship. Then even if he forgives me, there is still King Dedede, meta Knight and Waddle Dee.
Sunset: Is it possible that I could bring my new friends to your amusement park one day?
Magolor: Sure thing. I would be more than happy to get to know you a little more. hugs Sunset Thank you, Sunset Shimmer.
Sunset: hugs Magolor back You are welcome.
