Square Enix has shown a great deal of interest to add in elements from the Star Wars and Marvel brands into their upcoming game, Kingdom Hearts 3. Well instead of just new characters, there is a chance for players to get the tools from the aforementioned worlds.
Since Sora is going to get new Keyblade transformations, the weapon might just get the ability to change into a light sabre and this can be obtained when the protagonist has to go through a hidden boss fight against Darth Vader.
Also, a separate mission can see Donald Duck acquiring Captain America’s shield temporarily and this will aid the character in the fight against Master Xehanort.
Of course, this is just our ideas for the game and there is a possibility for Square Enix to share the same vision. Regardless of the outcome in Kingdom Hearts 3, we trust Square Enix to deliver a great game ahead.
