IX Armor

The iX Armor (イクスアーマー), written as EX Armor in Bandai's Mega Armor line of figures, is an armor used by Mega Man X and Zero in Rockman X Mega Mission 3.

When Return iX was shot in his back by Enemice HL, Return iX decided to suspend his fight against X and Zero and temporarily fused with the two Maverick Hunters to improve their power, becoming the iX Armor for them. When Zero was knocked out, the part of Return iX that was on him moved to X, improving his armor and becoming the R-iX Armor (known as All X Armor in Bandai's Mega Armor line of figures).

After defeating Mix Fort, Enemice HL used his Sigma Chip to turn into Sigma Limited, and he knocks down Zero. When Zero got unconscious, the part of Return iX that was on him attached to X, becoming the R-iX Armor.

R-iX Armor
The R-iX Armor (アルイクスアーマー) is an armor made of Return iX's body. X and Return iX combined their busters into a powerful attack that defeated Sigma Limited, but the armor vanished because of the amount energy used, presumably destroying Return iX. It is later revealed Return iX survived.

Trivia

 * Unlike traditional armors, the iX Armor does not replace X's original armor, but instead mounts additional armor over his standard armor. The original armor can be seen via transparant segments of the iX Armor.
 * The iX Armor and R-iX Armor were released in model kit form in Bandai's Mega Armor Series. The original release included only the new parts of the armor in plastic bags molded in clear plastic, which would mount onto the original non-transluscent X and Zero model kits to replace only select parts. Later releases of the figure included translucent versions of the X and Zero model kits along with the iX and R-iX armor pieces.
