Eruption is Ike's Standard Special Move in Super Smash Bros. Global Apocalypse. Ike lifts his sword and then plunges it in front of him which then explodes in a burst of flames. It can be charged up to 5 seconds, and the fire greatly increases its range. It has excellent knockback and range, regardless if not fully charged.
