Whispy Woods

Any%

As Wing Kirby, fly into the upper-right corner when the fight starts, face left, and carefully but quickly and rhythmically time jump-canceled dive bombs facing left to repeatedly hit him. Keep spamming this even during phase 2, when he's trying to suck you in (as long as your timing is good, you should never be low enough for him to suck you in).

100%

Grab the fire ability before the fight. Just before falling into the arena, do a fire spin to the right then burning to trigger the starting cutscene.

When the fight starts, stand next to Whispy, and breath fire to the right. Immediately after two hits, hold left to charge up an inferno. This does just enough damage to save one inferno hit at the end, but not too much to waste time.

In phase two, stop using inferno. Start charging one by breathing fire left to avoid hitlag, so you have inferno started before he starts sucking you in. Just stand there and inferno until he eats you; shake out as quickly as possible, grab the dropped fire ability, stand by Whispy and breath fire into him and start your third inferno. You should finish him with exactly two inferno hits.

Mr. Dooter

Any%

The general idea as Wing Kirby to deal with phase 1 is to do two jump-canceled dive bombs (maybe three if your spacing is perfect), then when you're too far to hit him with a dive bomb without moving, hover flap forward and feather gun once while getting close enough to dive bomb him again. Repeat. When he starts jumping, you should be spamming jump-cancelled dive bombs. You should never land on the ground a single time during phase 1.

In the second phase, while he's charging his super jump, you can do three sets of two dive bombs and a shockwave from slamming into the ground. The first time he lands from a super jump, dive bomb him once. Every time he lands afterwards, use a shuttle loop using a star from the previous jump. If he's not dead yet, then finish him off with a few more dive bombs; he'll usually jump high up (which in that case, chase him with more dive bombs).

100%

You should be coming into this fight as Water Kirby. Surf into the fight to trigger it.

The first phase is very straightforward. Stand by him and spam rainbow rain. The hitbox is big enough that you will always hit him, even while he's jumping. Make sure your timing is tight so you can abuse as much of the invincibility frames as possible, and minimize vulnerability frames in between.

In second phase, rainbow rain him while he's charging his super jump. When he lands the first time, rainbow rain him once, then drop your water ability (make sure it doesn't disappear!) and suck in the star that spawns. Every time he lands afterwards, spit the star out of a dash to damage him, and prepare the next star to fire at him. If you're unlucky, he'll bounce only 3 times, meaning you'll have to get water to finish him off. If you're lucky, you can finish him off without having to use water before it disappears.

Fatty Puffer

Any%

100%

You should come into this fight with parasol. Do two parasol drill to get close to it before it jumps out of the ground. When the fight officially starts, get close to its left and spam parasol twirls. Space them close enough so every hit lands, but far enough so kirby himself doesn't get hit in between each twirl. You will need to slowly move left, as Fatty Puffer will crawl to the left before jumping.

When phase 2 starts, it will make itself bigger. During this animation, you can land two parasol twirls on it before it starts rolling. Use parasol twirl to spot-dodge the roll attack, be near the wall he rolls into, and start using parasol twirls after he slams into the wall. You should finish him before he has a chance to attack again.

Grand Doomer

Metal General

Landia

Lor Starcutter

The best form of DPS is to spam fully-charged star shots (you'll shoot two uncharged shots in between). However, this is very difficult, and barely any faster than spamming spiral dragons assuming every star hits (if you miss a single star, then using spiral dragon is faster already). Thus, it's recommended to use spiral dragon repeatedly.
