The Monster II was an artillery robot used by the United Earth Expeditionary Force (UEEF). It was designed to replace both the HWR-00 Monster and the HWR-14 Thundercracker. The Monster II came in several different versions. Both space capable and ground combat only versions were fielded, as well versions with gauss cannons and particle beam armament. The Monster II stood slightly taller than an MBR-04 Tomahawk, making it much easier to deal with from a size perspective than both the original Monster and the Thundercracker.

Though the Monster II looked like it shared components with Maxwell’s VF/A-6 Alpha fighter, this was really not the case. Maxwell Dynamics purposely designed the legs and upper arm joints to resemble that of the Alpha, but it is not quite clear why they felt compelled to do so. The company line was that it would cause the enemy to confuse the Monster II with other, lighter mecha, making it less of a target on the battle field. No one really believed this, and the prevailing opinion was that the easily recognizable Alpha parts had become a big piece of Maxwell Dynamic’s “brand identity”.

The Monster II served with the UEEF Marines and Tactical Corps as a self-propelled artillery piece, and with the UEEF Navy in the anti-spaceship role. Though certainly smaller than the Monsters and Thundercrackers they replaced, the Monster II was still an obscenely big mecha and was only built in limited numbers. Additionally, its tall and top heavy form made it far from the best artillery platform ever built. Each cannon had to have a corresponding thruster in the back to balance the mecha when firing. This of course added weight and complexity to the design. Many of these issues were later addressed with the fielding of the much smaller HWR-30 Tiger.
