Entrance: A warp symbol appears, flames appear around it a little, and Roy is revealed.
Normal Attacks:
Neutral A: Mid-horizontal slash. Roy slashes up with one hand.
Forward A: Strong mid-horizontal slash. Same as adove with the difference that this time the attack is stronger and faster, Roy holds his sword with both hands.
Down A: Vertical slash. Kind of like Link's, Roy can send up his opponents upwards like in Melee.
Up A: Horizontal slash. It's like the one in Melee, difference is that Roy will hold the sword with both hands and we will not be... quiet, yeah.
Running Attack: Mid-horizontal slash. Roy moves his arm (right arm, the one which holds his sword) to his back, and then makes a mid-horizontal slash.
*Smash Forward A: Horizontal slash. Like his attack in Fire Emblem 6 with the Sword of Seals, Roy holds the sword with both hands.
Smash Down A: 360º slash. I think this doesn't needs description, oh... again, sword being hold with both hands.
**Smash Up A: Double Horizontal Slash: Sorta like Link's, again, in the first slash, Roy slashes up holding his sword with one hand, and in the 2nd one, he slashes holding it with two hands.
* If the charge is full, the sword might get chances of being in fire, making it stronger.
** The 2nd slash also may be with fire, chances will tell.
Nair: 360º spin. Roy spins while holding his sword in front, protecting himself.
Fair: Mid-horizontal slash. Again, Melee-like, but Roy holds the sword with both hands (to make it look stronger, yeh).
Uair: Horizontal slash and kick. The slash is like Melee, Roy holds the sword with both hands, and also kicks.
Dair: Horizontal slash. Roy slashes down, starting from his right this time, one hand-holded attack.
Grabs:
Neutral grab: Same as Melee, just a bit more... agressive.
Running grab: ...More agressive, again.
Grab attack: Roy punches his opponent with his right hand.
Forward throw: Roy punches his opponent with more strenght.
Down throw: Roy pulls down his opponent, puts his right arm on his neck and falls with him. (Maybe a suplex? I don't know that kind of moves)
Up throw: Roy punches up his opponent in the face (...ouch).
Back throw: Roy will send back his opponent and hit him/her with his shoulder.
Special Attacks (Note: All are Fire-based):
Up B: Blazing Dash. Roy will crouch and hold his sword with both hands, then he jumps 60º in front of him while spinning with his sword, his reach is sort of like Mario's Up B.
Neutral B: Blazing Slash: Roy closes his eyes and grabs his sword with both hands while he stands. A chargeable attack. When the charge is released, Roy will jump forward and slash down.
Forward B: Sealed Flames: Roy's ranged attack, Roy will hold up his sword with both hands while flames start to come out of it. Depending of how long is hold the button, the longer the distance where the flames appear (it goes straight though, if a wall is in the way, Roy automatically slashes).
Down B: Fiery circle. Roy will stab down his sword and create a circle of flames around him, like Ike's neutral B, but this is not a charged attack.
Taunt: Same as Melee
