Adaptive Armor

Adaptive Armor was armor that could adapt and shapeshift to allow its user the greatest advantage in any environment it was exposed to by detecting its surroundings via sensors. It was considered by its creator to be his greatest creation. The Toa Nuva were given this armor by Artahka when they entered his realm. The Toa first experienced the adaptation when they began falling in Karda Nui, prompting the Adaptive Armor to give them the ability to float. The Toa Nuva's Kanohi and Toa Tools adapted changed as well.

A projectile weapon was also included, and it could also adapt itself. So far, there are 4 known forms it has taken.

Normal
The armor's default mode was the Toa's original armor.

Aerial
When exposed to the skies of Karda Nui, the armor shapeshifted into a more aerodynamic mode, allowing the user to fly via different methods.
 * Lewa - Jets
 * Kopaka - Wings
 * Pohatu - Propellers

In addition, the armor created protective visors and provided a Midak Skyblaster.

Swamp
In the swamp, the armor shapeshifted into a form somewhat similar to its aerial mode, but with a few major differences.

Instead of equipment designed for high speeds, it had fins and jets which were less powerful than the Aerial mode. This prevented the user from sinking into the swamp.

A Nynrah Ghostblaster was included due to the Mistika Makuta owning them.

Vehicular
In vehicular mode, the armor adapted to fit the vehicle, removed weapons and the user's visor was shapeshifted to include fins for aerodynamics.

Trivia

 * Tahu was still wearing his adaptive armour when he was transformed back into his Toa Mata form, thus making him look different from his original form.
