Roy

“You have lost faith in humanity and in yourself. I believe in mankind, and I know that your lunacy must be stopped!”
— Roy, to Zephiel

Roy (pronounced /ɹɔɪ/[key][3]; Japanese: ロイ Roy) is the son of Marquess Eliwood of Lycia's House Pherae. In the Disturbance of Bern, he was entrusted with the leadership of Pherae's army in opposing the invading Kingdom of Bern in lieu of Eliwood's illness, later becoming the leader of the Lycian army as a whole following the death of Hector of Ostia, and ultimately assuming command of the Etrurian army. He sought to assist Bern's Princess Guinivere in finding a peaceful resolution to the war, to prevent King Zephiel's ambitions of exterminating humans and returning Elibe to the rule of dragons.

Roy is the main character of Fire Emblem: The Binding Blade, also appearing briefly as a child in the extended epilogue of Fire Emblem: The Blazing Blade and as a bonus character in Fire Emblem Awakening. He is also a playable character in Super Smash Bros. Melee, Super Smash Bros. for Nintendo 3DS and Wii U as downloadable content, and Super Smash Bros. Ultimate.
