Kingdom Hearts Ekko?
So when ekko came out i was playing kingdom hearts, when i saw his gameplay i knew they have so many things in common. Ekkos sword can be a keyblade and instead of square particles around him, why not have not have particles from kingdom hearts like crowns, hearts, or some kind of symbol for time. His q can be sora's attack in game by throwing his keyblade and have it come back, or you can try tinkering with his other spells to make an astonishing effect. his w can be changed to do the iconic attack that sora uses to heal or do and aoe spell, this is when he puts his keyblade in the air(with both hands) and shoots a projectile in the sky. his e can be similiar to sora's with him dashing towards a target and when he me makes contact you see the particles from earlier fly! finally his ult can be him going into his drive form or him doing a quick teleporting spell. well thats all, but if you can have his back animation have him open a door with his keyblade or even put a disney reference if you can get the copyrights!
