Roy
The Sword of Seals (SOS) is Roy's signature and ultimate sword in "Fire Emblem: Fūin no Tsurugi". Roy also wields it in Super Smash Bros. Melee.
Within "Fire Emblem: Fūin no Tsurugi", the Sword of Seals was the second sword wielded by the Legendary Hero Hartmut, the founder of Bern, a military nation in Elibe. It was used to seal away the Dark Dragon and end the Scouring, a war in which humans fought and exiled dragons to another dimension. 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.
It is not until late in the game (Chapter 22) that the Sword of Seals becomes available. At this point, the weapon is awakened by the Fire Emblem and reacts to Roy, class-changing him into a Master Lord. This weapon can attack up to twenty-five times (both direct and indirect) and can be used as an item to heal Roy. In addition to this, it also has increased effectiveness against all dragon-type units (war dragons, wyvern riders, mamkutes, etc.). Also, at the end of the extended campaign, Roy uses the Sword of Seals to seal away the power of Dark Priestess/Dragon Idoun.
In Super Smash Bros. Melee
The Sword of Seals is Roy's blade of choice, and is used in most of his attacks, excluding grabs and throws. In contrast to Marth's Falchion, the Sword of Seals is most powerful near the center of the blade rather than the tip, and has a multitude of fire-based attacks.
Trivia
- The title of the 6th Fire Emblem game is sometimes translated as "The Binding Blade", despite the "Sword of Seals" being the literal translation of the game's original japanese title.
