They'd fight, it'd be inconclusive and Kiryu would invite Donkey Kong to be a bouncer at his club

Because he can stab through your frontline party in-game to kill your backline, even if you're bodyblocking them with a massive griffin. That's a thing he does

Luca mainly due to Pauline getting hellmurdered real quick

That is what gives me pause here. I think Donkey Kong wins if he gets in grabbing range, but I also think Donkey Kong probably dies if Luca stabs him first. And Luca has a good amount of range going on those fire stabs (he can also run straight through your party with them, so I do think Pauline probably dies in the crossfire)

It's hard to measure Luca's speed given he's in a turn based RPG, but he always gets like three turns to your one so I assume it's Pretty Fast

Oh you know Luca would kill Pauline just to be a dick, and then this gets interesting

I dunno who wins but a giant rampaging gorilla escaping the training park seems like an everyday Squall occurrence

...how on earth is Ray nerfed in water. It's Ray

Theoretically infinite range but the rounds are designed to shatter on impact so they don't just keep going through a target and kill Jar Jar Binks picking his nose on another planet. At least I think that was the logic

Gun Lore: They fire by Weird Scifi Nonsense shrinking the mass of the bullet so the slug velocity hits impossible speeds. Also as far as I remember the guns don't actually fire bullets, they shave pieces off an existing block of metal in the gun and then rocket that off to kill things

As for how it would work underwater I don't think there's ever an underwater fight in Mass Effect, 'lol'
