Identical to the Shield Breaker used by Roy's partner Marth, Roy charges his blade up for a bit before releasing with a flaring slash (which Marth can't use). The difference between Shield Breaker and this attack is that Flare Blade can instantly KO any foe when fully charged. Roy will take 10% damage when a fully charged attack is released. An excellent edge-guard.

Blazer
A rising slash that sends Roy upward a good distance. An opponent hit just when Roy jumps will be sent forward in a blaze of flames (hence Blazer).
+
Counter
Roy protects himself with his sword for a short while. If he is attacked in this time, he will block the attack and counter attack.

Double-Edge Dance
By pressing three more times, Roy will launch a four hit combo. The attacks can be modified by holding up or down while pressing , allowing for many different attack combinations.
Roy slams his knee into his opponent's face. Very quick, but low damage.
Forward
Bounce
Roy puts his opponent into the floor, who proceeds to bounce off the floor backwards. Low damage.
Back
Throw Away
Roy simply tosses his opponent away behind him. Low damage.
Emblem Toss
Roy tosses his opponent straight upward. Only useful when opponent has a high damage level. Low damage. It is the second most powerful up throw in the game.
It is worth noting that, when smashing with a melee item (i.e. beam sword), Marth and Roy swing their sword first, followed by an item swing. Against low-percentage enemies, the first strike is a great check and provides excellent positioning.
