Well, as much gameplay of Odyssey I saw idk what a forward air dice is, but it's it's not organized in Imgur like what I showed then it's not worth it, this is very small thing to be covered. I claimed Kirby was more agile, Lunge disagreed while minimizing what was shown and now that he gives reasons as to why Mario's more agile they're pretty underwhelming, it simply makes sense to believe he just lied and exaggerated Mario. Maybe he can jump higher, given Kirby's small size and if we ignore how he can impulse himself on a level like a golf ball, but then next to the other factors he still has the advantage.
Just some nitpicks: I don't think slashing faster than others can fully see tells much about skill. Transforming Bowser into Giant Bowser is Size Manip. That's no "multi-person transmutation", each Toad was affected on that range, there's no reason for every 1 Toad to be affected with transmutation that can turn more than 2 persons into a brick. The Cook ability pretty much doesn't matter like the rest of Kirby's abilities, as the battle wouldn't last that long and Mario has no means to not get hit by Kirby's IC moves.
