Roy (SSBU)/Neutral special
Roy charges Flare Blade, swinging the sword down with an explosion occurring thereafter. It deals relatively high knockback even with low charge, though it isn't easy to land without reads. At maximum charge, which takes around 5 seconds, the move is treated as a one-hit KO that also breaks shields. Roy will take recoil damage if the move is fully charged. Flare Blade can deal slightly more damage if the move is released just before it reaches the one-hit KO threshold.
Flare Blade can be turned around during the charge, removing the need for a b-reverse. This also gives it minor utility on the ledge if spaced away from edge attacks. B-reversed Flare Blade does still have utility, however, as the momentum gives it minor use as an approach option, kill move or for general reads. It is committal, however, being -15 on shield and having a relatively long animation.
