Roy

The Sword of Seals, Roy's main weapon in FE6 and SSBM

The Sword of Seals is Roy's sword in the sixth Fire Emblem game. Roy fights with it in Super Smash Bros. Melee.

The Sword of Seals was the second sword wielded by Hartmut, the founding hero of Bern, a nation in Elibe. This particular blade is capable of reacting to the emotions and feelings of the one wielding it, as well as generating fire. Although it doesn't do so in Super Smash Bros. Melee, the Sword of Seals is capable of healing the wielder and unleashing long-range attacks using the fire it generates.

In Super Smash Bros. Melee, the Sword of Seals is most powerful near the center of the blade, and a lot of its attacks are fire-powered.
