Gravy's argument:

Aight, so we're on a huge terrain. I mean, real big. https://www.youtube.com/watch?v=X4b5Vp1DsCY

It's real long, don't expect anyone to watch it...but yeah, its a huge island.

Mario has canonically defeated DK, as well as Bowser, so there's an advantage there. But he's going to possess Dixie upon the teams meeting, which is 15 seconds of DK being confused why Dixie is attacking Diddy. His family is number one, and he'll be really sad they're attacking each other, which leaves him ripe for being attacked. Once the possession wears off, Mario will escape unharmed, and can use his Mega Mushroom to grow to the same size as DK, as well as use his Metal Cap and Lightning Bolt to shrink Donkey Kong and Bowser.

Pamela offers alot of utility including:
-Poison
-Slow
-Sleep
-Healing from her teddy bear

Keep in mind that she's a ghost, and is impervious to damage from physical damage. I'm not sure what hurts her this fight, truly, besides Bowser's Poison.

Anyway the centerpiece is Sonic, which here's a small sample of his combos from Frontiers:

He's so fast he teleports around while he attacks, which DK and Bowser will have no chance at keeping up with.

If things get dicey, the team can regroup: Pamela can fly, Mario has his flying cap, and Sonic can navigate the terrain wuthout any problems. Since they're on a huge island they can regroup far away and heal up their wounds while their opponents try to find them again.
