Well, the redaction leaves things to be desired there, at many times idk what topic you're talking about or what you aim to say.
1. When did he fight the sun and moon outside of Mr. Shine and Mr. Bright he didn’t even try to fight them in this context and frankly fighting and possibly killing them sounds like a bad move.
Mr. Shine and Mr. Bright are not the sun and moon, just like the Kirby-sized stars Dreamland had at the time weren't the real stars it has. Your premise is up its head and you don't even point it out, you can't just say that Kirby was already able to fight them and even kill them because he didn't show feats on that scale at the time. That he later had feats on that level means that he later could, the burden of proof is on you to imply he can do this and is as powerful, and what you came up with is that he already is. If he's that powerful by that time he wouldn't even need to fight them, just being in between them would make their blows land on Kirby, this would-be being so much more powerful than them, and then what, they wouldn't care and keep on their personal drama-based fight? Clearly he didn't try to fight them because he lacked the power to, not because he had too much power, that's too ridiculous. If "fight" is a strong word then replace it with "stop them physically".
You also ignore the part where the sun and moon can be talked too, is Kirby going to possibly kill them too if he tries that?
2. People for awhile though that was because the wings he got and he still lost to Kirby meaning the wish failed.
Common misconception between fans, like Dark Matter being a hivemind and many more. The pause screen des. inside Nova states that's his true form, and even then I would have no idea what was Nova going to do to Popstar if the wish was power to Marx.
3. The starship is one of the weird it was made by the items Kirby used to summon nova it seems to have primarily been to allow him to get in and move around in the first place it was also used to fight kabula and can make a helper.
I think you try to imply "part of the power of what Kirby did to Nova came from Kirby as he uses that Starship often", which says nothing of the other points, and would not be the case as Kirby uses star power to make it, the thing he doesn't have on his own and needed to collect across planets to get. Later on against Kabula he used another power source to he needed to collect to turn it into the Starship. Even then, the thing is comparable to his own power at the time as far as we know, it only took that to destroy Nova's insides.
And that nova was likely weaken after one an attack from galacta knight, two fighting halbert mode robobot Kirby.
Star Dream. Canon Star Dream wasn't attacked by Galacta Knight, the non-canon Star Dream who did end up stronger because of it. Star Dream still scales to Kirby and all, but the point was that it was being overpowered, which it clearly was, and that the power difference Kirby and Nova based on Super Star isn't the same as the power difference between Kirby and Star Dream in Planet Robobot.
that one was with the rainbow sword compared to the love love stick a weapon seemingly better suited to deal with dark matter as shown by it being made of the positive emotions they are weak to and doing your job right doesn’t necessarily mean you are more powerful the rouge one had its swordsman form. I am pretty sure the first one also exploded, the continent size dark matter aren’t proven to be stronger and zero showed up before and engulfed planet pop star and them blowing up after zero 2 died is a chain reaction that they shouldn’t scale to and what mini bosses the painting which wasn’t one or waddle doo, ado, and dedede aka fodder, boss, and 3 time final boss he didn’t actually fight the dark matter.
Dark Matter aren't weak to positive emotions in any meaningful way, if at all. That headcanon wouldn't be a thing if it weren't for Star Allies, and yet you argue against the mechanic of positive emotions across the series knowing it would totally justify the grows in power Kirby is listed as having, it's not thought through. Kirby would be harmed by the first Dark Matter. The swordsman form was a form he took, the second, true form is better. You can't just "the continent size dark matter aren’t proven to be stronger", you need to prove the small first one was stronger. 0 engulfed Popstar with an unknown amount of Dark Matter. Easy to say "chain reaction", but of what? If a human-killing bomb blows up and that makes more bombs blow up then 1 human-killing bomb still has the power to kill a human, 02 dying still makes it upscale in power to Dark Matter. You go extra unclear in that last part and I can't make up what you mean.
Skipping the first part of this one as that was just a claim regarding their goal.
You miss the common sense call in it; "Having more power than everyone comparable to an earlier Kirby is easily presumable."
Landia lost the master crown, was beaten up by Kirby and friends and took an unknown amount of damage in the area before also claiming power creep because the fought a guy with a shield they couldn’t harm without a super weapon is one evidence of a stone wall and two iffy.
There is no proof the good Landia was using the evil Master Crown it was guarding if he doesn't use the special transformation with the gimmick to do so. Landia recovered from that fight, hence when 4 players each play as "Landia" they are at full health. Not the first time you only grab in a small part of the context that fits in how you see things, the guy uses the same super weapon against Kirby & co., they can take it, later on he's a playable character and harms others with the same super weapon, every playable character can harm everyone who can take hits from it.
Sphere doomers? I am pretty sure they where always mini bosses. If you want to use that kracko and coily rattler were also mid bosses but I don’t think there’s prove they are as strong as the originals
