We already have Auron, so its not impossible. Theres a very good chance one of them will be a party member in KH2, most likely in HB. I thought of some Co-op moves.
Cloud:
Cross Slash - Sora and Cloud spin around eachother and swing their weapons in an 'X' shape.
Blade Beam - Press the triangle button at the right time to trigger this attack after Cross Slash. Cloud plunges his sword in the ground sending a wave of energy at the enemies.
Omnislash - Press Traingle at the right time after Blade Beam, Cloud hovers, surrounded by electricity and cirlces around sora quickly while slashing enemies.
Leon/Squall:
Renzokuken - Sora and Leon spin the weapons and perform a rising slash, knocking the enemies into the air.
Blasting Zone - While the heartless are knocked up in the air (from Renzokuken) press triangle to have Leon shoot them rapidly.
Fated Circle - Quickly after Blasting Zone, press triangle to have Sora propel Leon in the air, where Leon shoots a cirlce of energy onto the enemies on the ground.
what do u guys think of those moves?
