Kingdom Hearts 3: 11 Disney Characters That Must Feature

6. Arthur

Merlin's been a part of the series since the first game, teaching spells, gifting weapons and, of course, being the one to lead players towards the 100 Acre Wood along the way. Having Arthur join the series would give Merlin the chance to have a bit of an expanded role and allow Sora to repay the old wizard by helping train Arthur on his way to becoming king. With Sora having matured over the course of the series, giving him the opportunity to interact with the inexperienced orphan and pass on lessons he's learned to help the boy embrace his destiny would fall right in line with how The Sword in the Stone plays out, whether it's in its own fully-fledged world or a 100 Acre Wood-esque realm.
