The Giga Armor (ギガアーマー Giga Āmā) is an armor from Rockman X Mega Mission 2 used by X in the fight against Tackione's final form. As Zero was tired because of his previous battles, he gave all his remaining energy to X, along with the Neo Armor and Neo Buster. The armor became the Giga Armor, a powerful armor equipped with the Giga Buster and Giga Saber (Tackione's Saber Grap). With it, X is able to use the Giga Crush attack, which destroyed both Tackione and the Giga Armor itself by using all of its energy.
The Second Armor is nicknamed "Giga Armor" by fans.
