Geno Flash

Geno Flash is the final and most powerful attack Geno learns in Super Mario RPG: Legend of the Seven Stars. He learns it at level 17 and it takes 16 Flower Points. To time correctly press and hold the Y button until the third star appears. Geno transforms into a cannon and shoots a ball of energy at all opponents. Upon contact, the ball rapidly causes a large explosion which portrays a sun. The sun continues to keep growing larger until it fills the screen, then suddenly discharges, causing severe damage to all enemies.
