Hastur

The Hastur has the unique ability of carving out space as its main form of combat.

Used offensively, the Hastur's spatial carving ability enables the wearer to attack their opponent with an invisible force, with a thrust of the palm causing a distortion of space being sent to destroy whatever is in its path or a hand grip gesture allowing the wearer to crush their opponent with carved space from opposite sides. Upon impact, the spatial attacks are devastating enough to bring down strong combatants such as Okarun, whose injuries from being crushed by the space around him were so severe that he had to be put on life support. The wearer can also grab ahold of the carved space to attack their opponents from up close.

The Hastur wearer can use the carved space to swipe away anything heading towards their direction, sending them to the suit's pocket dimension on its back. This helps the Hastur wearer to avoid any incoming attacks and even banish opponents from the battlefield if they are in close-range. The wearer of the Hastur can choose to release whatever they have stored away, which can be another form of offense depending on what they are sending back at their opponent, such as the Hastur Kur redirecting a wave of debris back at Momo after the Esper previously sent it towards the Kur as an attack.

The spatial carving also allows the Hastur wearer to shift the position of their opponents. In the midst of battle, the Hastur wearer can rob an opponent a chance to land an attack by shifting them back and can pull them in towards them to close the distance and attack. As a result of this tampering of space, the Hastur wearer's opponents end up being caught off guard and are usually left too late to do anything to defend themselves.

Defensively, the Hastur wearer can block oncoming attacks by placing carved space between themselves and the attack, which was shown strong enough to protect the Hastur Kur from an All-Out headbutt from Okarun.

While the spatial attacks are strong it is possible to cancel them out if clashed with an attack of equal power, such as Momo's Moe Moe Tri-Beam that is capable of destroying exosuits with a single shot. An opponent with enhanced speed that is constantly on the move can make it difficult for the Hastur wearer to land a hit with the carved space or to shift their possession, as the few times it is shown to work is when the opponent remains stationary.

The Hastur possesses its own dimension that stores whatever the wearer swipes away with the suit's ability to carve out space. The storage space is located on the suit's back from which everything that is sent is visible on the two large holes.

The dimension is able to store an infinite amount of whatever the Hastur wearer has captured inside the suit's body. While any living thing is kept alive within the dimension, it is impossible for them to escape unless the wearer wishes to expel whatever is inside.

However, as demonstrated by Momo, if the Hastur wearer just so happens to absorb a being who possesses powers that transcend dimensions, then it can be made possible for them to force their way out using a special attack. This will result in the Hastur taking major damage due to the attack being unleashed from within.

The tail of the Hastur can be used as a weapon, as the tip is sharp enough to pierce through flesh, shown when the Hastur Kur impaled Bamora through her abdomen.
