Updated headcanons for dynamic between Dark Meta Knight and Shadow Kirby
Back then, I headcanoned these two to be enemies.... but as I now feel differently, I've decided to change these headcanons. This is one of the things I touched on in my post of things that I've changed for my headcanon verse, this post will go over the updates on my thoughts for DMK's and Skirby's dynamic in greater detail.
I now headcanon that they eventually become friends.
DMK and Skirby didn't get off to a good start. During the events of Amazing Mirror, DMK was of course helping Dark Mind on conquering the mirror world, which Skirby was against. Skirby however wasn't a good enough of a fighter yet to be capable of stopping the conquest, as he had to count on Kirby to do just that.
Even several years after the ending of Amazing Mirror, these two still didn't get along. Dark Mind was still alive as a weak fragment that then desperately needed DMK to do his dirty work, which he did. For a while, DMK was still doing bad things in Dark Mind's name. One of these bad things was helping Dark Mind feed dark magic to Joronia through the mirror that Taranza gave her, which eventually lead to her spiral into being a mad tyrant. Dark Taranza and then Shadow Dedede also came into existence to be additional hitmen for Dark Mind, increasing the threat even more. This needed to be stopped.
While DMK continued following Dark Mind's orders even with the latter being a fragment, Skirby often left the mirror world to go find Kirby and ask for training on how to use copy abilities. Just like his pink counterpart, he wanted to be a protector for his homeland, as he was determined to stop the threat of Dark Mind for good.
Eventually, after Skirby learned how to use copy abilities and became well-equipped to fight thanks to Kirby's help, he then set off to stop Dark Mind's persistent threat. He was able to succeed in this as he found Dark Mind's fragment and destroyed it with the Sword ability. This angered DMK, who then attacked Skirby in attempt to avenge his master, but failed.
Skirby had trained well enough by that point, and was able to beat DMK in a fight. He then told DMK that Dark Mind was a horrible influence on him, and that he was better off without that vile master around to keep convincing him to commit crimes.
DMK scoffed, as he was stubborn and wasn't willing to believe Skirby. He went on to "try to find a way to bring Dark Mind back". But at one point, he gets jumped by both Dark Taranza and Shadow Dedede, who considered him a 'traitor', but luckily Skirby was nearby to help DMK as they teamed up to beat those two and make them go away.
That right there marked the start of when DMK and Skirby started becoming on better terms. DMK initially didn't want to admit it, but he was actually grateful that Skirby helped him out there. It could've gone badly for him otherwise. It took a while for DMK to truly warm up to Skirby, but they eventually became friends. He didn't want to do this at first, but DMK managed to get to the point where he came to terms with not having Dark Mind be a part of his life anymore.
Dark Taranza and Shadow Dedede didn't care to follow suit. They just decided to go on with their lives elsewhere in the mirror world, not caring enough to get along with either DMK or Skirby.
Although despite becoming friends with Skirby, DMK wasn't really interested in redeeming himself. He wasn't interested in becoming a good person, and he didn't care enough to seriously participate in mirror world society. He just wanted to do his own thing and live unplugged from other mirror worlders. He claimed Moonlight Mansion as his home, with the previous residents leaving the place to go elsewhere. Most mirror worlders live far away from Moonlight Mansion now, as it's DMK's residence.
Skirby was fine with this, just as long as DMK isn't complicit in being a threat to the mirror world at large again. Skirby regularly stops by to visit. DMK didn't mind it; he's largely antisocial and doesn't really care to change out of that, but doesn't mind Skirby's company at times.
A lot of the time they have together, they just chill out in peace.
This routine largely continues on even after Star Allies.
DMK initially did not plan to join Kirby and all the other dream friends during the events of Star Allies. And for a little bit, he really didn't even want to. But because the Jamba heart pieces reached the mirror world and threatened the place, DMK felt like his hand was forced. As a matter of fact, it was originally Skirby that was going to leave the mirror world to then presumably join Kirby and co, but DMK decided that he wanted to "put this shit to a stop himself" and made his move.
DMK became the one to leave the mirror world instead of Skirby. He told Skirby to stay in the mirror world to protect it from the Jamba heart pieces that entered it, as DMK then went out to stop the source of the threat, joining Kirby and all the other dream friends in the process.
By the way, during Star Allies is when DMK first became friends with Kirby. It was also when the vast majority of the other dream friends first met him.
After Star Allies, some of the few friends that DMK made decided to occasionally visit him in the mirror world. It was the others of Wave 2 that visited him... Daroach, Adeleine and Ribbon. Skirby met them in the mirror world and became friends with them. Skirby effectively joined the Wave 2 friend group, as he grew a big liking for them all. He then decided to hop out of the mirror world out of interest to meet all the other dream friends later in time.
DMK and Skirby sometimes visit Popstar post-Star Allies. There are times where it's together, and other times when it's just one or the other.
Funny enough, most of the other dream friends get along better with Skirby than they do with DMK. DMK does not give a crap about most of the other dream friends. He's only friends with Kirby, the rest of wave 2, and Flamberge. The only reason he cares enough to visit Popstar sometimes is to visit Daroach and Adeleine, as he considers the former to be his best friend.
Skirby is DMK's second best friend, but they're still buds in a way. Even now, DMK is still antisocial, stand-offish, rude and still not a good person. He's still prone to unnecessarily violence and is not exactly welcome in many parts mirror world society, but he's grown to care about Skirby. Even if he has trouble coming around to admitting it at times, but he in fact does.
Skirby sometimes gives DMK company, and he also works to keep him in line from going too far in doing shitty things. And while Skirby understands why DMK is unpopular amongst most of the other dream friends, he comes around to help stop many fights that DMK has gotten into with some of them, mostly Marx + Wave 3 who DMK has pretty serious beef with.
What a journey these two have had together. The mirror world counterparts of Kirby and Meta Knight have made a decent bond, even if their dynamic isn't quite the same as their regular counterparts.
