The Warboss is a hybrid combination of the Destroya and the Grind Gear mechs, combining the melee power with the range capabilities of both mechs. The Warboss utilizes the base body of the Grind Gear and incorporates the Grind Gear's made weapon, the six chainsaw arms. His feet are also now weaponized with powerful talons that allow him to grip and tear apart large objects with just his feet. In addition to to these weapons are the ranged weapons of the Destroya body, including the newly upgraded homing omni-missiles and a superlaser built into the Warboss's head. The Warboss maintains it's heavy armor and utilizes powerful thrusters to enable mobility as well, utilizing the Machina's Anti-gravitation technology to assist the Warboss in maneuvering.

Much like it's Grind Gear, the six chainsaw arms on the Warboss model are individually capable of tearing apart nearly all types of armor on their own, combining powerful plasmic energy and indestructible adamantine alloy teeth to rend anyone unfortunate enough to be on the business end of these blades. They are also capable of combining into a single drill-like formation which, at full power, is capable of tearing through time and space to strike though the multiverse and destroy anyone caught in the path. By utilizing every possible iteration this attack ensure anyone caught in the path of the blade is somehow destroyed, seeking whichever alternative universe and applying it to ensure that happens.

The Warboss is also now armed with clawed feet with built in thrusts at the "sole" of the feet, now only allowing the Warboss to maneuver as if equipped with rocket boots, but also burn any foe in his grip or caught in the blast. The claws have a startling amount of dexterity as well, allowing the massive mech to handle extremely small objects with his talons, such as keyboards and firearms.

New additions to the Warboss's body are the missle launch packs built into the shoulders, legs, and belly of the mech. The ammunition in the body can be fabricated through the use of nanomachines, essentially allowing an infinite amount of ammo, albeit with "Cool down" time for the nano machines to fully replenish the ammunition. This also allows the Warboss mech to convert the missiles to different types to suit the combat situation, such as anti-infantry, barrier busters, or anti-magic, or teleportation canceling. The Warboss can change his loadout at anytime as long as the missiles are still inside his body. He can also launch these missiles in any direction, even ones he's not immediately facing. This will allow him to attack targets above, below, and behind him without turning around.

Built into the Warboss's head is a superlaser powered by solar energy, more efficient than the former nuclear core that the previous bodies had. However this reactor is not made for self-destructing, but to power the Starkiller superlaser. Utilizing the power of a miniature sun inside of the Warboss's head, the Starkiller converse the mass of the sun into a single focused laser capable of striking (And collapsing) the sun itself. One use per battle.

The Warboss utilizes the same thrusters as the Grind Gear does, but now equipped with a Eezo (Element Zero) Generator that simulates a localized gravitational field around the Warboss, allowing it to alter gravity around it to assist in mobility, or to help hold it's ground. Incidentally, the Eezo Generator serves an additional role as a personal barrier for the Warboss, as the Eezo Generator could create condensed fields of energy to divert or block attacks at the cost of using more energy than if it was simply used for maneuvering.

Lastly, the Warboss greatly differs from the rest of the previous forms by being a piloted mech. Replacing the Fusion Reactor common in the other bodies, a highly efficient cockpit is is installed specifically keyed for Endian-01. Not only does it require specific energy frequency from Endian-01, much of the operation of the Warboss utilizes the use of her hard light projection, such as the interface. In exchange of the loss of the massive Fusion Reactor, the Warboss is equipped with a highly efficient radar system that allows the pilot to maintain precise battlefield awareness. The Warboss is still equipped with a powerful self-destruct mechanism, however the sheer power is not quite the same as the nuclear-powered explosion as it previously had. It is however still powerful enough to completely obliterate the Warboss into particles, and anyone else who is too close to the mech upon self-detonation. To ensure the pilot's escape, the Warboss's cockpit is also keyed to a teleportation beacon, allowing the pilot to teleport to the beacon prior to the mech's destruction.

Named after Krieg's old maid, the Mu Drones (There are currently two of them, Mu-01 and Mu-02) are cheap, easily constructed drones that follow Endian and assist her in battle. Not only do they alert her of enemies, they are capable of intercepting attacks and attacking foes with their pulsar lasers or plasma cutter. They are also attuned to Endian's Hardlight projection, allowing them to not only be unaffected by their attacks, but let Endian use her Hardlight projections through them, increasing her potential range by utilizing her drones.

When taking the form of Grafdakka, the Drones can be employed outside of the mech in order to repair damage done to the mech. They can also be deployed in larger Combat Drones equipped with heavier weapons and more equipment. Not only are their weapons upgraded into twin-linked vulcan cannons and buzz saws (Similar to the Destroya form), each one have their own shield projector to deflect or blocking attacks as well as more powerful repair tools to repair damage done to Grafdakka.

The Drones are not indestructible and on their own often require multiple attacks to kill most foes. However they are fast and durable. When destroyed new versions will be teleported to Endian though the Combat Drones take a longer time to respawn due to the time it takes to recreate their bodies.
