(I'm making this because I read @MML!opinions!Fun!Chocolate! headcanons and I wanted to try one.)
In the planet Popstar, there was a kingdom called Dreamland, found by the self proclaim king, who's son then became the "true" king of Dreamland. 3000 years later would, Dreamland would have the youngest, and strongest, heroes in the whole universe.
The king was Denis Debbie Decker,(See what I did there) or DeDeDe for short. And the protector was a glazing knight by the name of Eric(His two voice actors in smash and the anime have the same name), or Meta Knightmare as his knight's name. Despite how they look, they weren't, "fully" adult yet. Heck, Dedede and Meta knight were 16 to 17 years old.
There was a pink puffball who came to Dreamland do to taste there best food. He was a traveler who never had a home. He just ate because he just like food. There was a young waddle dee who was different from the other waddle dees at Castle DeDeDe. He didn't want to work there, he was thinking what to do. Their names were Kirby and Dan, or Bandana Dee as a nickname. Yet, Despite their looks,(Yeah, we're doing that again.) they were 11 to 12 years old.
And then there was no name. He crash landed on Popstar when he was rejected by his family. He didn't know what was going on. Actually, I'm being told that he doesn't know anything going on. He was a gooey being that was 15,000 years old, or 15 years old in Popstar.
And those are the five heroes of dreamland who will defeat monsters from outer space and other worlds. And, wait I'm being told that I should stop talking now.
