Roy

Roy (ロイ Roi) is the main playable hero in the sixth installment of the Fire Emblem series of tactical role-playing games. Roy was included in Super Smash Bros. Melee as a playable character for the purpose of "previewing" the sixth game, which was released in Japan after Melee, making him the only character thus far in the Super Smash Bros. series to be included for that purpose. His appearance in Melee, along with fellow Fire Emblem character Marth, increased global interest in the general franchise, prompting the series to be released internationally from the seventh installment onwards.

Character description
While HAL Laboratory obliged to include Marth as a playable character in Super Smash Bros. Melee by popular Japanese demand, the sixth installment of Intelligent Systems' long-running Fire Emblem fantasy tactical-RPG series, Fire Emblem: The Binding Blade (Fuuin no Tsurugi), was nearing the end of its development. Nintendo decided to include that game's main character, Roy, as a playable character in addition to Marth to serve as a preview of the game for Japanese audiences, making Roy the only character in the Super Smash Bros. series to be featured for that purpose. It was a successful ploy to Japanese audiences for both Melee and The Binding Blade, but since this involved a game franchise never distributed outside of Japan beforehand, Nintendo was wary of keeping the unfamiliar fantasy swordsmen in Melee in its North American and European releases, but decided to keep them in based on the approval of western gamers. Roy and Marth, as new and original anime-inspired characters with rather effective fighting abilities, became popular enough in Melee that the Fire Emblem franchise gained international attention from the gaming community.

Intelligent Systems followed up with the franchise's seventh installment, subtitled Rekka no Ken ("Blazing Sword") but whose North American version is simply titled "Fire Emblem", designed with the international scene in mind rather than Japanese exclusivity. To this end they made it a prequel to The Binding Blade, set in the same Fire Emblem universe and chronology twenty years before Roy's quest, and starring Roy's father Eliwood, whose somewhat older resemblance to Roy was meant to appeal to players of Melee. The game's story is laid out with ten introductory chapters starring one of Eliwood's allies, Lyn, meant to introduce players to the Fire Emblem style of tactical play, and the other 20+ chapters are the main game itself. Blazing Sword's story is also structured so that knowledge of The Binding Blade is not required, and if the sixth game were played after the seventh, it would feel like a direct continuation.

Roy is studying in the province of Ostia, away from his home province of Pherae, both of which are in the nation of Lycia, when the militant nation of Bern begins to conquer various other nations on the continent; while his father Eliwood turns ill, Roy is called in to lead Pherae's army alongside the other armies of the League of Lycia against Bern and its ruler, Zephiel, who displays a mysterious thirst for world domination. Zephiel's errant younger sister, princess Guinevere, escapes Bern and comes to Roy in defiance of her brother's motives, hoping to negotiating a treaty with Lycian nobility. Roy quickly agrees to her proposal to search for a peaceful means to end Bern’s aggression, and it is in part this encounter that will eventually lead him on a journey across Elibe to save the continent from what could end up being a war with powerful dragons from a different dimension. He is ultimately successful in his endeavors when he defeats Zephiel. However, if all the legendary weapons of Elibe were gathered by meeting certain conditions ingame, the weapons would start glowing and pointing toward the location of the Dark Dragon, Idenn. A few extra chapters take place which results in the defeat of Idenn. Afterward, depending on certain ingame factors, different characters experience slightly different endings, but generally peace returns to Elibe and everyone lives happily ever after, with various rebuilding of respective countries. Roy is notable for having the most potential wife endings, depending on who he supports.

Binding Blade/Sword of Seals
The Binding Blade, translated as the Sword of Seals, is Roy's weapon. It was 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. Roy would later take the Binding Blade as his main weapon following his promotion to Master Lord, and would use the blade to seal away the power of Dark Priestess/Dragon Idunn.

Roy uses the Binding Blade in all his attacks except his pummel and throws. It is referred to its Japanese-translated name in Melee and Super Smash Bros. for Nintendo 3DS and Wii U, and is referred to as its localized name in Ultimate.
