Will

Will (short for William), is a supporting character in Final Fantasy Adventure and its direct remake Adventures of Mana. He is known as Willy in Sword of Mana.

Final Fantasy Adventure & Adventures of Mana
Will was a slave and gladiator of the Glaive Empire who developed a friendship with Sumo and Amanda. However, he was tragically wounded in one of the routine duels with the beasts sent by the Dark Lord into the arena pit, and dies, though not before delivering his prediction that mana power and the Mana Tree itself are in grave danger. With his last breath, Will tells Sumo to seek out a man named Bogard for further information and aid. Sumo is perplexed and barely able to grieve, but vows vengeance for his fallen comrade.
