Ezio is obviously a light weight character who specializes in quick attacks. His normals mostly use a sword and hidden blades.
Neutral Special: Hidden Blade
A command grab where he punches forwar. If this hits an opponent he’ll then stab them with a hidden blade on his wrist and then throw them away.
Side Special: Hidden Gun
He aims his hand forward and then shoots from a gun on his wrist. The bullet doesn’t do much damage (I imagine guns probably didn’t back then) but it is pretty quick and big. It’s also a bit difficult to hit the opponent with it since it’s difficult to sim it properly.
Up Special: Leap of Faith
He jumps upwards then dives forward in an arc
Down Special: Eagle Vision
A counter where he holds his sword for a second and a white effect goes around him. If he’s hit then he’ll knock the opponent away with his sword.
Final Smash: The Flying Machine
He swings a hidden blade forward which leads into a cinematic. In the cinematic the opponent is on the roof of a building in Venice and Ezio glides in and kicks them off.
