Story Information
Pilots: Introduction:
  • Echo
  • Solid
 The Hammer Rock, often touted as the "Small Iron Kong" is a powerful Zoid sporting high power, melee abilities, and versatility surpassing even the latest Zoids of its class. This is why it was chosen by Prozen himself to be mass-produced for the Prozen Knights in preparation of "X-Day", the beginning of the Neo Zenebas rebellion.  [1]

- Details of Design

Cockpit & Chest Hatch

 The Hammer Rock has an especially well-armored cockpit for a Zoid of its size, with the clam shell style cockpit encased in a metal 'helmet' of sorts. This helmet can flip backwards, far enough that the cockpit underneath can still open wide.

 The Zoid also has a hatch in its chest, though this doesn't seem to be given any particular purpose, showing just more metal components and a cap in the center.

- Military History


ZAC 2101, Late October ~ November, Attack On Valhalla

As October came to a close, and almost as soon as his ambitions had been uncovered, Prozen launched a rebellion in the capital city of Valhalla. He deployed an elite combat division known as the Prozen Knights, with Hammer Rocks forming a solid portion of their small-scale units. Though the imperial palace had guards, they were all heirs of famous families who'd never actually been in combat before. To say that the battle was one sided would be an understatement. With five armored divisions and five mobile infantry divisions, all composed of former Zenebas soldiers who had dedicated their lives to Prozen and his cause, the capital was overrun. The Guylos flag was set ablaze, replaced with the flag of the Zenebas Empire, which had perished 50 years ago. The rise of the Neo Zenebas Empire was officially announced, with Prozen as its first emperor.

Even as the Hammer Rocks ran out of ammo, they challenged the Geno Saurers of the Guylos Empire to melee combat, fighting bravely until the end. This dedication went so far as for pilots to climb out of their wrecked Zoids and charge their enemies with rifles. This was because the soldiers leading this assault were all of advanced age, and had entered the fight knowing they wouldn't survive. The purpose was, instead, to ensure the success of the Neo Zenebas uprising. For that, they were all willing to give their lives. In the end, Prozen, like his soldiers, sacrificed himself to destroy Valhalla, taking a large portion of the Guylos and Helic forces with him.

This sacrifice dealt a massive blow to both enemy armies, and also served as a signal for Prozen's son, Wolff Muroa, to begin his invasion of the Central Continent with the goal of reclaiming the Zenebas homelands.


- Notable Facts


  • The customize part "Omni-directional Missile" was, lore wise, specifically ordered by Prozen as a potential upgrade to the Hammer Rock.

  • While the Hammer Rock was technically a part of the later Guylos Empire, this is only so far as Prozen was. The Zoid hid under the Guylos flag as it received minor modifications to bring it up to modern standards, and then was deployed exclusively in the Prozen Knights.  [2]

- Equipment Information

- Guided Anti-Air Missile x4

Guided Anti-Air Missile x4 誘導対空ミサイル×4

 These missiles are installed to the back and can rotate up and down for anti-air use. They're said to be comparable to those found on flying Zoids.  [3]

- Hammer Knuckle x2

Hammer Knuckle x2 ハンマーナックル×2

 The Hammer Knuckles refer to the fists, and we can probably assume on the basic merit of it being a gorilla that this Zoid packs quite the powerful punch. Especially given its said to do well in close-range combat.

- Twin Beam Gun x1

Twin Beam Gun x1 連装ビーム砲×1

 The Twin Beam Guns are typically stationed on the right shoulder. Their mount allows them to rotate left and right by a surprising margin considering how close they are to the head. The weapon is intended for close-range combat, firing energy shots strong enough to destroy small-scale Zoids in a single hit. It's also depicted being installed to the top of the arm, similar to how the Iron Kong used to hold its shoulder armaments.  [3]

- Vulcan Gun Pack x1

Vulcan Gun Pack x1 バルカン砲パック×1

 This gun is attached to the left shoulder, and likewise can rotate left and right. It's typically intended for small-scale Zoids and infantry.  [3]
