Beautiful, beautiful, beautiful idea.
... But you better keep addressing the Kirby anime and characters and they should be... Not how 4Kids corrupted them to be.
That would make me quite upset.
Anyway, I'm not too sure about Sikieiki and Komachi. Dedede is immature, and Escargon is intelligent, while happening to play a victim role.
Although the only immature antagonist that comes to mind could be Remilia, with Escargon more likely to be Patchouli than Sakuya.
Personally, I think Mokou could fit the Knuckle Joe / Sirica personality quite well, but this isn't too necessary.
In the end, I'm sorry to say I actually didn't have much to contribute. But this concept is still a big deal to me, considering that Kirby is absolutely awesome and wonderful and super and great and excellent and yeah
Alright, alright, I'll keep addressing the characters by their original names then, and refer to this parody as 'Kiryuko of the Stars'.
Great to see another Hoshi no Kirby fan around here :*
The reason I made Shikieiki Dedede was mainly for that name pun. Shiki also has the highest political position of all the known characters, she's extremely bossy and her hat resembles a crown. Her blue and green outfit also fit Dedede's blue penguin colors. And since Shiki is a judge, judges mostly use hammers, we got Dedede's hammer taken care of too. Shikieiki would be some kind of reverse Dedede: Instead of ruling in a careless and selfish way she'd rule as a strict queen, making lots of rules to make people abide the law and follow of her view of good, and going haywire whenever someone breaks the rules. Despite ruling in the opposite way, she'd still be no better than Dedede. Escargon is a snail, and always thew butt of jokes to Dedede. Komachi is lazy and slow like a snail, and she also gets punished frequently for her blunders by Shiki.
Dedede also hates Kirby's guts because he's an outsider, different and gets all the attention of the kingdom. I could imagine Shiki to dislike Yuyuko too because she's a ghost, and thus mocks the laws of life and death by merely existing. Yuyuko is also extremely careless, in contrast to Shiki's strictness. Dedede buys Demon Beasts to get rid of Kirby and get back in the spotlight himself again. He wants to rule again in his own fashion without some pink marshmallow ruining his plans every day. I can imagine Shiki to be driven to such edges too if it means to keep the order. Since it'd be wrong if she killed someone herself, she'd just get Yuyuko chased away by buying demons from Shinki, who is fully taking advantage of the situation, like Nightmare. Like Dedede, Shiki would slowly learn how to rule in a better fashion along the way, but remaining a bit of a prick anyway.
But I can see why Remi would also be a good pick... She fits Dedede's personality way more. Spoiled, greedy, selfish, stubborn, mean and bossy. She also fits Dedede's royalty style more, and she's also insanely rich like Dedede. She'd be more prone to make ridiculous political decisions for personal gain and amusement. She's also way more violent, allowing her to beat on her minions like the King. She'd also be pompous and gullible enough to fall for Shinki's offers, like Dedede did so many times when Nightmare offered him something. And if Remi would be Dedede, Shiki could be Mayor Len. The Fairy Maids would be the Waddle Doos, and Sakuya would be Waddle Doo! The SDM would function as Dedede's castle, and Dedede's favor of crimson and red fits Remi's favor of scarlet. Patchy would indeed make a good Escargon. Escargon was intelligent, clever and cunning, but ultimaly always ended on the worst end of his and the King's schemes. Patchouli has knows Remi the best and second-longest of all the other SDM members, and I can imagine they thought up quite some plans together, with Remi being the one with the idea and Patchy converting it into a functional plan. And Patchouli's bad health can be reflected in Escargon's snail qualities, not being very fit himself. Perhaps these two are better fit for Dedede and Escargon afterall.
And yes, Mokou's battle style, attitude and revenge complex fit Knuckle Joe's characteristics. Sirica is a bit too cool headed for Mokou, but Knucle Joe fits perfectly. Meiling was a bit too much of a ditz to fit Joe personality-wise. Not sure who should be Sirica now though...
And I think Daiyousei and Cirno would make a better Fumu and Bun afterall. Their personalities fit them better, regarding Daiyousei's big sis complex and Cirno's prankster habits. They also live near the SDM, which fits with the fact that Fumu and Bun live in Dedede's castle. Letty could be either Sir Ebrum or Lady Like, but I'd still need someone for the other role....
But thanks for all the help!
