Blazer (Fire Emblem)
From the Super Mario Wiki
Blazer is Roy's up special move in Super Smash Bros. Melee and Super Smash Bros. for Nintendo 3DS / Wii U. When used, Roy leaps into the air, slashing 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.
