Kingdom Hearts 3: 10 Final Fantasy Characters Who Should Be Included

4. Red XIII

First Appeared In: Final Fantasy VII

Of all the Final Fantasy games, no characters have been as big a part of Kingdom Hearts as the ever-popular VII's. Cloud, Aerith, Tifa, Yuffie, Cid, Zack and Sephiroth have all shown up, though there are still a few leftovers who could join the fray. 

To that end, the courageous and intelligent Red XIII - or Nanaki, if one prefers - offers up a different, non-human type of Final Fantasy character for Sora to interact with, and watching or fighting alongside him taking down Heartless would be an undeniable pleasure.

Alternatives: Same goes for Vincent Valentine and/or Barret.
