I've only played 3 Spyro games: Spyro: A Hero's Tail (GameCube), The Legend of Spyro: The Eternal Night (Wii), and The Legend of Spyro: Dawn of a New Dragon (DS). So, I'll do what I can with his moveset.
Side Smash - He rams forward with his horns
A-A-A - Horn Attack
B - Electric Breath - I made it this and not Fire Breath because I thought it would be too generic. We already have Bowser and Charizard with the same one.
Down B - Horn Attack - I can't remember the name of it. But, it's from Eternal Night. He swings his horns upward. If it lands, Spyro jumps up and kicks them to the ground
I'm sorry, but this is all I could think of. Also, add me to the supporters, please.
