Guy is one of protagonists of Lufia II: Rise of the Sinistrals as well as its remake, Lufia: Curse of the Sinistrals. He is also a playable character in Lufia & the Fortress of Doom, but is only usable in the prologue of the game.
Guy is an optimistic warrior from Tanbel who is always up for a duel or a bit of adventure. He places a great deal of worth on a person's physical strength and is immediately impressed by Maxim's fighting spirit. He is fiercely competitive. Early on a brotherly rivalry develops between him and Maxim as to who's stronger, although this is eventually overshadowed by his much greater rivalry with Dekar.
In the Curse of the Sinistrals remake, Guy wields an axe as his weapon of choice. This was a major change from the original, as Guy preferred swords in Rise of the Sinistrals. This is evident in his game sprite holding a sword as well as being able to equip all swords (with the exception of Dual Blade & Dekar Blade). Axes in the original Lufia II were usually equippable to Dekar only.
When Guy's sister, Hilda, is kidnapped by the Sinistrals' servant Camu, Maxim and Tia volunteer to help him rescue her, and he subsequently joins them on their adventure out of gratitude. He has a great respect for Maxim, even offering to stay behind and die with him as Doom Island collapses. At Maxim's urging he instead leaves with Artea to spread the news of the Sinistrals' defeat.
As a result of his disciplined lifestyle, Guy lives to be well over 100 years old. He is still alive during the events of Lufia & the Fortress of Doom, though he dies after meeting Maxim's descendant and finding out the Sinistrals are back. Following his death, he is buried in his garden.
Guy is a physical damage dealer with high health, but his speed is lower and he can't use magic.
In the remake, it is Guy's girlfriend Jessy who is kidnapped instead of Hilda. He wields a giant hammer, furthering his position as the main tank of the party (aside from Dekar).
- Square Enix's Estpolis site states that Guy is 24 years old and 195 cm tall.
- He's voiced by Kenta Miyake in the Japanese version, Estpolis DS.
