Cook Kirby has transmutation.
He will use his copy abilities that he can use at will if he needs to.
Well, I'm almost sure this mini game isn't cannon, but the fact he can also get copy habilities trough contact means he can get fighter from asura by touching him
???
This minigame literraly has him fighting marx and nightmare after both had alread been defeated, this one isn't
I still find it to be a huge stretch, because Kirby pulling out the cook ability to instantly oneshot an enemy is totally not in character neither if you look at it from a lore perspective nor a game mechanics one.
They still don't grant multiplier, and Asura himself has several way to increase his already higher AP.
To an extent, they never made him so fast that he could blitz opponents, and Asura's got experience against similar opponents, aside from his Analytical Prediction that helps with that.
That remains a single instance in a mini game tbh.
The stone ability is very ineffective in combat, since it forces Kirby to an immobile state and he can only deal damage by dropping onto Asura, something he can easily counter with greater skill, prediction and LS to toss him away.
Actually, Asura still outranges Kirby by a large degree as said a few times.
