Fargo uses AquaBall on Serge.
||Hurls a large sphere of water at opponent. Inflicts Flu.
AquaBall is a 3rd-level Blue Element in Chrono Cross. This element summons a massive water droplet from water vapor in the air, the caster drops it atop the head of a target, causing moderate damage. Bubbles rise from the wreckage and blue rings span from the feet of the target once the water drop dissipates. The dampness causes the target to contract the Flu.
Incarcerated below the decks of the S.S. Invincible, Serge and his accomplices find an AquaBall element in a chest shortly after the ship is boarded by undead creatures. While any playable character can use this element, Fargo, when fought as a boss, uses this element when his Hit Points become critically low.
Aqua is synonymous with water, the natural element behind the move.
