Giga Attack

The Giga Attack (ギガアタック) is a powerful attack from the Mega Man X series that X can use with his armors in Mega Man X5 and Mega Man X6. Like the Giga Crush, a Giga Attack converts energy taken from enemies into energy for the Giga Attack's gauge. When the gauge is full, all energy accumulated can be released to perform a powerful attack, being helpful to escape from an emergency. However, unlike the Giga Crush, the range of the attack varies, not all of the being full-screen attacks.

Mega Man X5

 * Falcon Armor - A full-screen attack like the Giga Crush.
 * Gaea Armor - The effect is almost the same as Falcon Armor, but the attack range is very short, only harming nearby enemies.

Mega Man X6

 * Falcon Armor - A full-screen attack like its previous appearance, but with a background effect included.
 * Blade Armor - Uses the Z-Saber to slash and send energy waves forward.
 * Shadow Armor - Uses the Z-Saber to summon two large crescent slashes that spin over and under X.

Trivia

 * In Compendium of Rockman X, the Ultimate Armor's Nova Strike is considered a Giga Attack in Mega Man X5 and X6. It is noted to be different from the others in that it doesn't require a gauge and can be used any number of times.
