Stardust Tyrant

Stardust Tyrant (スタルダスト タイラント, Sutarudasuto Tairanto) is an artificial Sacred Gear created by Bellerophon.

Summary
After obtaining a copy of Azazel's research into Sacred Gears, Bellerophon used the Sephiroth Graal to create a soul suitable to his needs and forged it into an artificial Sacred Gear.

Appearance
In its initial state it takes the form of a high-tech silver gauntlet which encases Bellerophon's left arm.

Abilities
This Sacred Gear is peculiar in that it cannot fully operate on its own and requires working in tandem with other items and Sacred Gears to reach its full potential.

In its base form it can store items, such as Śūnyatā and Chaoseater, generate light weapons and barriers to protect its wielder as well as employing constraint fields to restrain targets. Even then it's generally considered a support-type because its main ability is summoning limited numbers of Aetherius Sentinels and remotely controlling several of Aetherius' functions, as well as commanding the Stauros.

Shadow of Sundered Star
Shadow of Sundered Star is the Balance Breaker form of Stardust Tyrant. It encases the user in a dark red undersuit covered in silver plates resembling an Aetherius Sentinel.

The Sacred Gear interfaces directly with the wearer's mind, providing them information at will and allowing them to simultaneously process the collective sensory experience of thousands of constructs like the Stauros or the Aetherius Sentinels. The armor constantly monitors the user's bodily functions, managing those normally taken care of by sleeping and resting, allowing constant activity without side effects or fatigue, as well as providing a limited form of regeneration and poison resistance.

It increases the defense of its wielder through a skin-tight barrier, capable of attuning itself to best counter different forms of attack with repeated hits.

Its summoning abilities increase to the point that the user can open a portal big enough to let the Stauros through.
