Well shit son.
He could probably be on the floaty side, but possesses a weakness to midair spikes and shit. He may be a bit heavy too.
I could prolly make his moves a reference to the moves Ghetsis' Hydreigon has, since his is the most notable one. Though, this Hydreigon would probably have no relation to Ghetsis, jus' mere coincidence.>Neutral-B: Focus Blast
A chargeable attack that, when fully charged, fucking HURTS. It takes a while to fully charge though, so that's something.>Side-B: Fire Blast
A slightly slower but also slightly more hurtier PK Fire. It lasts a little while after the projectile bursts.>Up-B: Dragon Rush
Hydreigon charges up for a moment and you can select where he goes, he then rushes.>Down-B: Frustration
A counter move that gets stronger when Hydreigon takes more damage.>Jabs and tilts
His jab may be just rapid biting with his head hands, ending with a headbutt from the main head. (Hydreigon can learn Bite and Headbutt)
His side tilt is a smack with his tail (Dragon ail)
His up tilt is a harsh swing of one of his hands that moves in a sort of arc (Brutal Swing)
His down tilt is a lower whip of the tail (Dragon Tail again)>Aerials
Not really sure about these desu
N-Air could be a pulse of darkness around Hydreigon (Dark Pulse)
F-Air could be a slow, harsh strike that can spike (Superpower)
B-Air could be another slow attack with an especially shiny tail (Iron Tail)
Up-Air could be a particularly fast attack with his tail (Acrobatics)
D-Air has him falling downwards belly-first, spiking anyone in his way (Body Slam)>Smash Attack
F-Smash is Dragon Pulse, a big blast with surprisingly OK range.
Up-Smash is Hyper Voice, a roar that strikes those above him and to less of a degree on the sides
Down-Smash is Surf, a downwards slam that unleashes two blasts of water that hurt but also work like Mario's FLUDD
