Flame Sword (フレイムソード Fureimu Sōdo) is the Special Weapon Mega Man obtains by defeating Sword Man in Mega Man 8. Befitting its name, it is a close-ranged fire-based weapon, capable of igniting things that are highly flammable, such as the Thorn Vines in Search Man's stage. Flame Sword can be executed on the ground and in the air, and even underwater. On the ground, Mega Man will perform a horizontal outward slash, and in the air, he will perform a downward slash. It is especially useful on Search Man himself, as it can burn down the bushes he hides behind and prevent him from ever using his Homing Sniper, and it's also Frost Man's secondary weakness. Despite having short range, it has very high power, dealing more damage than usual against a good amount of bosses.

This weapon is also the most effective special weapon for fighting the second form of Dr. Wily's Wily Machine.

  • For Bliking, it is the only boss in Mega Man 8 to take a different amount of damage from each strike from the Flame Sword (3 units of damage the first strike; 2 the second time; 3, 2, 3, etc.), hence the data value in its field above is listed in fraction form.
  • Cut Man and Wood Man are available only in the Sega Saturn version of Mega Man 8.

Other appearances

Super Smash Bros. series

Mega Man uses the Flame Sword in the Super Smash Bros. series of fighting games as his forward air attack. This attack involves Mega Man quickly summoning the Flame Sword to his hand in midair (rather than morphing his hand into a Mega Buster that emits the blade), and performing a downward swing with it in front of him, much like when the move is used in midair in Mega Man 8. The attack inflicts 9% damage or 5% if the sword hits the opponent at the end of the move, and has a fire effect, true to its name.

Other media

Mega Man used the Flame Sword against the Wily Machine in the Rockman 8 manga. Instead of being made of flames, Mega Man's sword is identical to Sword Man's.
