Blazer is Roy's up special move. He uses it in each of his appearances starting with Super Smash Bros. Melee. When Roy uses Blazer, he leaps into the air and slashes his sword up with a fire trail. Blazer is a slower attack compared to Marth's Dolphin Slash, but deals multiple hits of fire damage. The angle at which Blazer travels can also be controlled by tilting the control stick. The move can also be reversed on startup to make it stronger.
