Claustro

Claustro (クレストロ) is a weapon developed by Detnerat and used by Re-Destro.

Description
The Detnerat Patented Burden-Amplifying Steel Pressure Mechanism: Claustro is a wearable suit of armor designed for the Grand Commander of the Meta Liberation Army, Re-Destro. With the use of this support gear, Re-Destro is able to amplify his Stress Meta Ability to at least 150%.

The armor itself is made from mechanized drones that are kept underground. When called upon, the drones surface and connect to Re-Destro's giant, amplified body to create the suit.

The separate pieces of the armor can be dispersed on command and used to fly through the air. The Claustro armor was destroyed in Re-Destro's battle with Tomura Shigaraki.

Trivia

 * The name of the weapon likely comes from the term, which means a fear of being in confined spaces and being unable to escape, referencing how Rikiya becomes surrounded and confined by the armor he wears in order to fuel his Stress.
 * The armor's design seems to be similar to that of the Marvel armor Hulkbuster, also they both consist of multiple parts, which are stored in a hidden place.
