Project Thunder: Harmonia
So in this case the rescue team (Kirby, Tune, Arle and Link's crews, along with Nimbus's SMGs, Tama's Pokemon, Blotch, Tonio, Piper and some extra characters) knows exactly where Nimbus is; at the resistance's main base, trying to keep everything under control. Some of the team goes there (not all, there's limited space) to meet her, and they manage to convince her to believe what's going on and eat the meme. She is, of course, so relieved to see her friends here, but there's still the situation at hand to deal with. Fortunately, they came prepared.
Despite pulling from the fewest sources, they've got the biggest team by a long way thanks to just how many characters the Kirby, Zelda and Puyo Puyo franchises have, so they've got plenty of troops to deal with all the bosses. As a reminder, there's one in each Kingdom (two in Luminos thanks to Lumiere) so yeah that's A Lot of guys who showed up. They also brought along the Halberd, one of the few ships they didn't manage to Codeproof in time, which is a much more formidable headquarters that what the resistance has been using.
Not sure who handles all the bosses (except that every team besides the one that fights Lumiere has at least one version of Link), but I have figured out a few:
-Ethil's boss is fought by an aquatically based team led by Sidon and Serilly (a mermaid with severe social anxiety who's one of Arle's friends).
-Magnamiel's boss is a massive bird fought mainly by flight-capable characters (most notably Digi Blade, been a while since we've seen him), but Dapple obviously also gets involved since that's her home!
-Stagnus's boss has already been being kept at bay by Magnus personally, and he gets backup from a team led by Bowser (who he gets along extremely well with), Yunobo, Draco Centauros, and Magolor (bit of an odd one out there I'll admit).
-Devos is getting liberated by Tonio and Piper's team (of course) and since that's where Tama is Blotch and Tama's Pokemon came with them (well, Hoopa's a bit occupied being the one who's deploying everybody but he can do that from anywhere, especially since his Unbound Form is fully available unlike in the last crisis). Dark Meta Knight and the Squeak Squad are also there.
-Lumiere's Tower (yes he has a tower now. one of the perks of selling out his universe) is stormed specifically by Arle, Rulue, Schezo, Satan and Lagnus, since even with the power of the Twilight more-or-less on his side he's not likely to be much of a match for four seasoned world-saving adventures and the Devil Himself, so this frees up Nimbus and everybody else to focus on actually important things.
He also has a minor slipup that makes Arle realize he recognizes her, meaning he isn't being affected by the firewall and is actually playing along and helping the CCC, presumably because he realized the potential benefits to his plans to make Nimbus('s power) his own. All five are understandably pissed now, Satan especially (since, you know, it takes every line he won't cross in his own pursuit of Arle and tapdances on them)... and Arle informs the others that there's no need to hold back.
[It Was at This Moment He Knew; He Fucked Up]
-Meanwhile, Luminos Castle gets stormed by the Main Crews of Kirby, Link and Tune, as well as Nimbus herself and most of the resistance. Nimbus is back in her original design, Tune having found one of her spare suits and suggested that if she's going to be liberating her kingdom, she should do it in style so everyone knows the Songbird is back. most of the group gets caught up in a battle with the possessed Royal Guard (led by Valiant and Ambrosia because of course) while Nimbus, Tune, Kirby, Dedede, Link and their SMGs and MRUs keep going to the boss; Melody.
It's a very intense, emotionally charged fight that I cannot write here due to the format we're dealing with, at one point there's a duet between Dedede and Possessed Melody that gives the real Melody the strength to fight for control, Nimbus gets to show off that she's way better at using Memes than she used to be, fun times all around. When she's defeated and the group is checking to see if she's okay now she actually pulls Dedede (who caught her when she collapsed after the Twilight was purged from her system) down and kisses him.
"You have no idea how long I've been waiting to do that."
Freeing her freed the other possessed characters as well, so now we leave them waiting for word on the other bosses and the eventual extraction.
