Level 1: Charges forward a short distance with the huge ram horns from his Skylanders version.
Level 2: Summons a companion from either YotD or Skylanders, like Heihachi's Level 2.
Level 3: Goes into the Final Fury mode from TLoS that he battled Cynder in, with the strafing and giant purple fireballs. Either that, or they could use one of his other furies and just have it as a Cinematic Super.
Mmm... these are my ideas:
1st: A quick Headbash on the ground, like Jak's Super level 1 >.<
2nd: Summon Sheila or Bentley in front of Spyro and send your foes away!!! (Like Sly level 1)
3rd: Comet DASH!!, it's a Very Fast Fire Charge attack, Surrounds Spyro with fire and kill every opponent on his way (Like Fat Princess Level 1 range attack)
1st: Supercharge for a few seconds (sounds like PaRappa super 2 xD)
2nd: Elemental Fury, surrounds Spyro with a special Aura and kills in a mid-extended area every foe in that area.
3rd: Summon Sgt.Bird, he follows Spyro and shoot some Rocket Lanchers to the opponents
1st: Super Fly and Fire Ball Powerup, Spyro can FLY and Shoot an Infinite amount of Fireballs to the opponents for a little while (it last 10 or 15 seconds).
2nd: Dark Fury, the Celestial Moons come together to make a huge and darker eclipse and touch Spyro with Darkness. Spyro has the ability to kill everyone with just one hit and every breath attack turns darker and powerful with an extended Range and also Spyro has a incredible speed to catch their enemys, it last for 15 seconds.
That's are my ideas ^-^
