aggresive mostly, can be defensive for a little bit, beat up or get beat up
Mecha koopa combos make him tag team a bit like Rosa but more offensive.
a grappler with great down through follow ups, but combo
can play any playstyle though they are more grapplee than anything. Can do anything good but not great
If you can live to see it, Rageicario is super deadly at 20%, but thats if you live to see it. Mix up and play safe.
Pelet zoning game is amazing and can go aggresive with the metal blade combos, but he's really hard to use.
Grappler. Copy paste combos and crazy kill power but if you're not good at recovering you loose too every character... except
...R.I.P.
If you've got a good eye for keeping track of which pikmin are next up, you'll be hard to track for your opponent, but keeping track is really hard.
Hit and run master. You shoot in, combo a lot, shoot out, make them approach or leave an opening, shoot in. Rinse and repeat. Also edge guarding is nice.
Gyro combos. But you're also combo food. also get used to hearing beep boop.
Does not play defensive. Play defensive and you loose. You can't be scared. You get in their face and dominate them. Be relentless.
"Monando" is a jack of all trades thing and if you can handle really bad frame data your mix ups can give you the match.
Aggresively defensive. Projectile frenzie to the face and bomb combos make him very hard to beat, but don't rely on getting grabs much.
If you can handle tricky set ups and small characters you'll win every mu. He's so good.
Similar to roy but safer and can pace and be defensive.
Grappler who hates projectiles but hits you in the face really hard.
Since you were already able to point out Ness and Mewtwo above the others, I say go Mewtwo. He can play both playstyles and win any matchup. Just make sure you kill first.
