Eruption

Eruption is Ike's standard special move in all of his playable appearances in the Super Smash Bros. games. Ike holds his sword in the air before plunging it into the ground, creating an explosion that damages any nearby opponents. The move can be charged by holding the special move button, and automatically strikes once fully charged, though a fully charged Eruption deals 10% damage to Ike. In Super Smash Bros. Brawl, the attack creates red flames, but in subsequent installments they were changed to blue.

While the attack can be powerful when it is being charged, a full power Eruption actually delivers less knockback than some of the weaker stages of the charging process. In fact, the stage that comes before Eruption reaches full power can potentially one-hit-KO most fighters. On a side note, the full power Eruption delivers horizontal knockback, while all the other charging stages deliver vertical knockback. Additionally, Ike begins flashing red when Eruption is almost at full power.

In Super Smash Bros. for Nintendo 3DS / Wii U, Eruption has two custom variants: the first is Tempest, which cannot be charged as long and replaces the fire with wind that pushes opponents away; only the sword can deal damage, and a fully-charged Tempest does not damage Ike. When used in the air, the move does stall Ike's falling speed for a moment, which can help with his recovery. The second variant, Furious Eruption, creates larger explosions that deal more damage to both opponents and Ike; the move can also damage Ike before it's fully charged.
