Lore heroes (calling them that for some reason) versus two main protagonists of Square Enix with almost identical hairstyles, Sora and Cloud.
I can argue great for 3 characters. The only Zelda I've touched was Link's Awakening for the Game Boy, say 12 years ago, and I never even gone halfway through that.
K, Fierce Deity Link is enabled and as well as Final Form Sora. The thing about Ryu and Cloud is they have no super forms (unless Ryu transforms via the Dark Dragon Blade, but that would be horrible spite imo).
So Final Form and Cloud, vs Deity Link and Ryu. No magic or items. Just melee.
Depends on what is meant by feats. If anything related to gameplay doesn't count, then perhaps. I'm not in the position to say all gameplay should be excluded unless it's Final Fantasy, which has the most awkward gameplay in my opinion.
KH gameplay is pretty realistic. What usually isn't is all the talk of damage points, how much health points you have, invulnerablity, etc.
But something like reaction commands, moves character have, those are things they can do. FF has those two. I'm saying numbers gauging health and damage, glitches, and similar things should not be regarded.
Gameplay should tell what characters "can" do. It doesn't make sense they can pull off something in a game (I'm talking about moves in the game, not something like "Sora can one shot Sephiroth at level 142343")
Final Form Sora lacks any greater strength, speed, and durability feats better than regular Sora. All we know about it is that it can do the same things as Sora and can float and TK two keyblades.
It's even more different for Fierce Deity Link. We don't have anything to go on except Young Link's feats and that FD Link can shoot beams from it's sword.
