Honestly, Kirby is a great secondary for Megaman. Played right, he makes a solid answer
when played correctly. Not easy wins in some cases, but definitely much better than Megaman and a lot of other character in the cast by comparison. I don't know Megaman's matchup against
well but I'd imagine him being tough thanks to packing solid projectiles of his own a nice close quarters game to go with it. However, Kirby does well against him too has he can float over the gyro, duck lasers, juggles R.O.B, is hard for R.O.B to hit and grab, isn't too hard to gimp, and can take R.O.B's lasers and use them against him. I am not sure if he's really a problem for Megaman, but Kirby can do well against
too. While we have to respect his frame data, abusrd power, and ground game, we don't have to stay on the ground. We have 6 jumps which makes it easy for Kirby to bait stuff out and punish. We also duck a lot his moves which makes getting D-Tilts easy. Final Cutter can also through him off with good timing. Plus recovering against him is practically free unless you used up all your jumps and as for our ability to gimp him, well, I don't think I need to say much about that. lol
Also, I have a brother who played
with a passion in this game before making him a secondary, I can say that Kirby probably wins that matchup. It's lot like Sheik vs ZSS. A lot of the same advantages against Fox apply, only moreso here. On top of ducking lasers and being able to juggle him, we actually run faster that Falco and his recovery moves are easier to intercept. We can also crouch his grab at times and duck his N-Air. The main things you got watch out for though are his D-Air, D-Tilt, F-Air, and F-Smash. D-Tilt is a big one as it means you don't want to just carelessly run in on him as it's fast and kills. Short hop aerials seem pretty effective though. He also jumps higher so he'll be able to purse you in the better if he knocks you into the air. But it also means that he's easier to punish with Down B if you're both to high off the ground. In any case, he's definitely not a big issue for Kirby.
, I'd argue Mario is even and Doctor Mario, we beat. Their main advantage is their frame data, Neutral B, and FLUDD/Cape which can gimp Final Cuttter. However, you should never recover high against them in general really. In Mario's case, we have the edge of having better recovery, multiple jumps to bait out moves and punish, and in general he's not the most unpredictable fighter. In the case of both, we can take their neutral B and use them to great effect thanks to our multiple jumps. This especially makes gimping them even easier. From expericence, I'd say Mario : Kirby is even and Doctor Mario we beat since he's actually slower than us, was worse recovery, and no FLUDD.
, I don't know. While, she probably does beat Kirby, but it may be a lot more close than we realize. Luma's knockback and walling is dumb, but Kirby's crouch can actually quite effective in avoiding her grab and Luma. Our aerials, used right can beat out Luma, and if we take her ability, we can bean her and Luma as she lands. We can also exploit her recovery ruthlessly. Dabuz and Mike Kirby actually had a set back at Smash Attack 5, and Mike Kirby didn't do that bad considering it's well, DABUZ, and Rosalina benefits from customs pretty well too which makes her walling game even more potent. He actually opted to go Olimar following the first match.In the following Smash Attack, he actually won against Snakee as well. And this is all before the 1.1.0 buffs that really improved Kirby's combo game and we all saw how well Triple R wrecked Shydude yesterday right? While Rosalina is something to consider, I don't think she's the top tier Kirby has the most struggle against. I can see the matchup becoming closer or possibly favorable depending on future patches.
As I said before, between the both Megaman and Kirby, the main characters you'll want to watch out for is
However, the Pits, despite their range and disjoints, are beatable for Kirby. While their Dash Attack is a pain, many of their other moves can be punished well and Final Cutter can take them by surprise. I have some good Pit players on my campus, and I feel that Kirby can win as long as he respects their range, side B, and baits and punishes well. I should also add if they recover below the stage, they can be gimped as they have no hit box. If near the ledge, they'll use side B into it. Shield and punish if you can.
Pikachu is tough, but Mike Kirby has demonstrated how Kirby can handle the matchup:
If you use Kirby against Pikachu, show that you can handle QA or they will abuse it. Jabs appear to do well. Probably N-Air and Up Tilt too. Inhale also makes dealing with Thunder jolts easier. But remember in general that F-Smash is hard to punish.
The only character I can see being an utter nightmare for both is Yoshi.
Having said all this, while the two's coverage together is pretty good, it isn't flawless. I agree that a 3rd or 4th character can make things perfect. For other character to use, here are suggestions:
: Does pretty well against Yoshi thanks to speed, weight, F-Air, bananna, and kill setups. This especially shows in a set between Angel Cortez and Raptor:
I'd imagine him doing pretty good in other matchups too.
: Seems to do well against Yoshi and can go toe to toe with Rosalina thanks to his hard hitting moves and speed. Dabuz actually opted to use Olimar against Fatality instead of Rosalina.
: I don't think the Pits are too big of a problem, but she beats them along with Yoshi and Rosalina. She can be hard to use though.
: While not as good as before thanks to the nerfs, I still think he beats Pikachu as he's too floaty to combo, hits harder, has a N-Air to break combos and intercept Quick Attack, and good frame data to match Pikachu. Plus Pikachu's light so Back Throw can kill after some good damage.
These are just some suggestions though. It's a big game with big cast. Explore and see what works. I can say though that making Kirby a secondary for Megaman is a move you won't regret.
