Gaia

Gaia (ガイア) is 's down special move in Super Smash Flash 2.

Overview
When performed, Isaac summons a tall rock pillar that rises from the ground. Prior to it rising, a spell circle will appear on the platform directly below him, and the player can use the left and right directional buttons to position it. Isaac can delay the move by keeping the special button pressed, and the pillar will rise once it is released. Opponents that make contact with a rock pillar can be hit multiple times, with the first few hits dealing 2% damage each and the final hit dealing 5% damage for a total of 13% if all hits connect, as well as moderate upward knockback.

Origin
Gaia appears in Golden Sun as a Psynergy Spell. The ground beneath the enemy opens up and engulfs the enemy party in a wide reverse shower of Venus energy and medium-sized boulders. Gaia is available at Level 7 and also has two stronger variations called Mother Gaia and Grand Gaia.

Trivia
