Gestalt

"'A conventionally invulnerable, sapient war machine. Through the synthetic synapses in Gestalt's bulletproof head flows the training of hundreds (if not THOUSANDS) of S-3LFs. The signifigantly larger cranium has been utilized to house the quantum machinery that prevents typical Abomination insanity, but even at a cursory glance this framework is only just holding him together...cognitively speaking.' - Unit Description"Project Gestalt is an exceptionally large Mag. Towering to almost the size of an entire building at its peak, It is the result of a project created by Phobos as an attempt to achieve godhood. It will crush anything in its way with its huge body.

Gestalt is large because of the amount of S3LFs it has consumed. Phobos' plan was for Gestalt to consume The Other Place, containing a massive amount of S3LFs. That would end up in Gestalt being a lot more gigantic than they already are, making it impossible to terminate it.

It first makes an appearance in Madness: Project Nexus Classic as the final boss of a level in Chapter 1.5. It makes its return in MADNESS: Project Nexus as a main antagonist. It appears in various levels, making it as one of the final bosses in The Rush.

Personality
Gestalt does not talk at all throughout the games asides from its battle dialogue. It seems largely aggressive and only focuses on killing its opponents; it does not care if other allies are caught in the way of its destruction.

It will usually let out a large battle scream when it detects someone. Pain does not phase this creature, only upon Corpus loss.

Madness: Project Nexus Classic
Gestalt appears in Madness: Project Nexus Classic as a regular Mag. They do not wield any weapons. Their head is covered with a helmet that has a small spike on top, pilot goggles, and a face guard that connects to their back. On the torso, there is a vest and armor with a backpack. Some of its flesh is exposed.

Upon the armor being destroyed, its entire body becomes visible. Rarely any skin is on Gestalt except for its face. Its flesh is visible from the skin being removed. When all the skin is removed, Gestalt's head is exposed, leaving a skull shape and red teeth. A large metal plate is visible on the back of its head.

MADNESS: Project Nexus
Gestalt reappears in MADNESS: Project Nexus, appearing bigger than ever. Each time they appear, they become bigger, assuredly from consuming S3LFs (only three variants of the size are shown).

This time, Gestalt's head is almost entirely covered in impenetrable metal. The eyes are glowing in a pinkish-purple hue. Unlike the older form, Gestalt has a jaw that can move. Its nose is covered by a beak shape, with tusks pointing outwards. Wires are connected from the beak to a device on the back.

There is a metal set on the body with armor underneath. Its flesh is still visible.
