By holding the Special Button, Roy continues to hold the Sword of Seals behind him, essentially charging the move. As a visual indicator while charging, Roy will flash orange, flames will gather around the Sword of Seals, and a charging sound effect will play. The level of charge determines the damage and size of the explosion. As charging progresses, Roy will flash faster, more flames will gather around the Sword of Seals, and the sound effect will speed up. After four seconds, Roy will let out a battle cry and automatically release Flare Blade, inflicting 10% recoil damage.
Flare Blade deals between 6-45% damage, 50% fully-charged sweetspotted, and 36% fully-charged sourspotted. The knockback is also dependent on the charge, but fully-charged inflicts high knocback that can OHKO most characters.
In Super Smash Bros. for Nintendo 3DS and Wii U, Roy can release a fully-charged Flare Blade without inflicting recoil damage if timed correctly, but compensates with higher startup, shorter duration, and increased charging time.
Flare Blade serves as a good defensive option, as it can easily force opponents off Roy due to the size of the explosion. It also serves as one of Roy's most powerful KO options, as charging it halfway can KO as early as 45%, and fully charging the move will result in a OHKO against most characters. However, charging Flare Blade leaves Roy vulnerable, so caution should be taken if Flare Blade must be charged to KO capacity.
