Apparently there was a Rocket Racoon moveset leak.
From Noble Cactus of SRK
:qcf:+:atk:Blaster shot. Rocket whips out a blaster pistol that shoots pink lasers. Standard projectile with rapid fire properties. Damage scales quickly. You might be able to get a short juggle with it as your opponent is falling.
:qcb:+:atk:: Reflector. Rocket takes out a reflector device that emits a hexagonal, blue shield that blinks and reflects projectiles as well as pushes opponents away. It has a special property where, if you use a wavedash, you can cancel the reflector into any other of Rocket's moves. You can even cancel into another reflector, and the person I talked to said you might even be able to do an infinite this way.
:rdp:+:atk: Raccoon Illusion. Rocket dashes forward at blinding speeds. Deals small damage, but pops opponents up.
:dp:+:atk: Fire Raccoon. Similar to Gamma Charge, but cannot be followed up by another. Looks like Skrull's Skrull Torch. Slow and punishable startup, but can send the opponents into a spin knockdown.
Rocket Looking to be pretty legit
