The LS0/ACF-V3aC-020 Hammerhead is a Garrisai from the *Harbinger* Universe. It is piloted by Daniel Sherman.

## Technology and Combat Characteristics

The Hammerhead excels in using a plethora of ranged weaponry, from railguns to rockets, and hammers to cannons. While it is not the best at long range, its performance at medium to short range is well beyond the units of its time.

As Sherman and his men were tasked with eliminating the rebellions dotting the landscape of Cassiopeia with their own Garrisai armies, he was able to heavily modify his own machine with an entire arsenal of weapons. Due to the sub-camera attachments on the sides of the head armor resembling a shark, Sherman decided to name his Garrisai the Hammerhead. It was acquired as a mock-version of the NU METACOM System developed (and scrapped) by Nu Helix many years ago.

## Armaments

- 100mm Single Barrel HPNC: Being derived from the Dreadnought’s Twin 100mm HAMGs, these two-barreled weapons were split up and mounted in the chest for added stability when firing. With a five round internal magazine, they can be fired multiple times as a devastating mid to close-range weapon.

- Shoulder Vertical Swarmfire Missile Launchers: Each Shoulder is equipped with an integrated swarmfire missile launcher, which can fire a salvo of a variety of small missiles. Originally built from the Pinata II Missile Launchers of the Urban Dreadnought, they were relocated to the shoulder armors for an aerial bombardment-style attack pattern. Just like the Heavygun System of the Urban Dreadnought, the Hammerhead Heavygun System is used to allow these rockets to lock onto multiple targets, ensuring each one of them hits their mark. (It may be possible that the Hammerhead is also equipped with an additional pair of these missile launchers, fitted into the backpack binders in place of the simplistic sub-arms.)

- Twin Forearm Wrist Grenades: Also known as the “Wrist Rockets,” these customized launchers are derived from the underbarrel grenade launchers attached to 40mm Rifles. Typically firing up to four glass grenades in a single capacity (two loaded, two stored), they serve as medium-range backup weapons.

- Retractable Anti-Armor Blades: Derived from the Urban Dreadnought’s original Anti-Armor Blades, this forearm mounted gauntlet acts in a similar fashion to that of the T-33 Retractable Dual-Blade Gauntlet. When deployed, the two blades extend from the armored gauntlet, allowing for effective armor-piercing attacks. Alternatively, either of the two blades can be removed from the Gauntlet, serving as a handheld weapon.

- 60mm SAWMAC: Stands for the [Strategic Assault Weapon] Modified Automatic Cannon. A variant of the MAC “Lance Rifle” seen mounted on the LANDSTRIKE KAI System, this is a more compacted version of the high-powered rifle and the Hammerhead’s primary weapon. When not in use, it is stored on the rear skirt armor. Alternatively, a second one of these weapons can be equipped and dual wielded in exchange for the 500mm MPNCs, mounted on the backpack’s simplistic sub-arms.

- 500mm Coiled Railgun: This altered version of the 500mm MPNC is equipped with an electromagnetic accelerator for a faster projectile speed. Currently known as being the highest-caliber ballistic weapon ever wielded by a Garrisai, it is held in a similar fashion to the 200mm Recoilless Artillery Gun and used for long-range heavy shelling attacks. The Hammerhead is often equipped with two of these massive cannons, using its four-point lockdown anchors to fire both Railguns at once. In retrospect, the Hammerhead is also the only machine capable of effectively wielding these weapons to begin with. When not in use, one or two of these can be mounted on the backpack via its simplistic sub-arms, which swing the cannon under the arm for the Hammerhead to wield. If needed, these weapons can be purged from the connecting arms.

- T-18 Telescopic Rocket Hammer: The main melee weapon of the Hammerhead, it features a collapsible handle and rocket boosters on its back for a compact yet destructive weapon. It can toss around enemies like nothing, and is durable enough to serve as an improvised shield. When not in use, it is stored vertically between the Hammerhead’s backpack weapon binders.

- CW-09 Giant Rocket Launcher

- CS-018 Tactical Shotgun

## Special Equipment and Features

- LANDSTRIKE ZERO System: The same prototype armor system used by the Urban Dreadnought that allows for the use of the Hammerhead’s integrated weapon mounts. Presenting better operation efficiency and ease of use compared to handheld weapons, the system is non-purgeable and usually requires specialized repairs and resupply. On its own it provides a considerable amount of defense, but by using the Variable Attachment Points on each of the forearms, it can alter its loadout depending on the situation. The Hammerhead inherited this armor set from the Urban Dreadnought, using the benefits of the Arcandy Compact Frame to better boost the stability and accuracy of the integrated weapons installed in the armor.

- Four-Point Lockdown Anchors: Using two copies of the Lockdown Anchors found on the Cyclops Ground Type, the Hammerhead’s Four-Point Lockdown Anchors provide an even greater amount of stability than their predecessor. Mounted on both the front and rear of the lower legs under the knees, these anchors rotate downwards, using driving spikes to plant the Garrisai into the ground. The additional spikes mounted in the feet themselves create an even greater amount of stability as well. While perfectly capable of being used to stabilize the firing of the Hammerhead’s various weapons, its most prominent use is when using the 500mm Coiled Railguns, which with any other Garrisai would cause the internal frame of the machine to fracture.

- VFO Sub-Cameras w. Augmented Targeting System (Hammerhead Heavygun System): By attaching the head of the Urban Dreadnought to the Arcandy Compact Breaker, it meant the Hammerhead inherited the Urban Dreadnought’s Heavygun System. Unlike the standard Assistive Targeting System, the Augmented Targeting System allows for the multi-layer targeting of the Hammerhead’s Systems, where an onboard AI can be tasked with remotely operating a select number of its weapons without the pilot needing to control them. In other words, while the pilot focuses on dodging or maneuvering the Garrisai, the AI automatically targets all immediate targets, resulting in a greater amount of performance. In combination with this system, the Hammerhead is equipped with a Hi-Sensitivity Targeting Sensor and FrameBreaker Visor, both of which further increase the machine’s accuracy and combat capabilities. These systems are mounted on either side of the Hammerhead’s head, which when combined with the external shell over the head armor, give the Garrisai the resemblance of its namesake hammerhead shark.

- Backpack Fin-Binders: (Named after the fins of a shark) Mounted on either side of the Hammerhead’s backpack, these custom variable attachment points can be used for a variety of things. By default, they are mounted with a pair of extra thrusters for an increased movement speed. Alternatively, they are equipped with a set of storage racks and sub-arms, made to hold any combination of the Hammerhead’s arsenal. Primarily, Daniel Sherman prefers attaching either a pair of the 500mm Coiled Railguns, or a pair of the 60mm SAWMACs.

## History

The Urban Dreadnought was defeated by Jack Kendall in 2572, its chassis being captured by the Mercury Legion as a political symbol. After spending a few years like this, it was eventually retired to the stockpiles of the Mercury Legion due to its already extensive damage.

Daniel Sherman would launch a covert operations attack (titled Operation Last Midnight) on the UNI in 2579 (a year after their reveal and subsequent expansion), after word of an experimental next-generation Garrisai based from Resuga technology was leaked. This would end up being the prototype Arcandy Compact Breaker.

After Sherman stole the ACB (possibly with support from NOVA), he would equip it with the weapons and armor of the Urban Dreadnought. This was alongside other items such as the twin 500mm MPNCs, 60mm SAWMACs, and the Hammerhead Heavygun System. The only identifying features of the Urban Dreadnought were the armor parts (which were really only altered to hold integrated weapons), and the Heavygun System-Equipped head (coming from the UD itself). This head was covered with the Hammerhead Heavygun System, but would eventually be revealed upon its exposure.

Jack was initially offered the use of this machine by Dan upon his return but declined, as he had already mastered the controls of the high-mobility Diamondback. Instead, Jack allowed Dan to keep the machine for himself.

The Hammerhead would serve several years under the Mercury Legion, with Jack Kendall using Daniel Sherman as the head commander of the Legion's Garrisai forces. This would remain until the late stages of the Harbinger Uprising, in which the Hammerhead was defeated by the LCR, killing Sherman in the Process. It would then be retrieved by Alexander Baltimore in order to create the Harbinger Legacy.

## Trivia

- The Hammerhead is an oddly sophisticated hybrid of both Project Resurga and Arcandy design, with the machine inheriting the best of both designs. While using the frame of a prototype limited-production unit, its Project X augmentations have earned it its place as an Ace Unit.

- While originally being a moderately advanced Arcandy Frame, it was given the equipment and armor of the destroyed Urban Dreadnought.

- The Hammerhead’s ID Number is a hybrid between the Arcandy Compact Breaker and Urban Dreadnought’s. The code is mainly from its Arcandy Frame, with the LS0/ and 020 coming from the Urban Dreadnought.

- The Hammerhead takes a strong inspiration from the Gundam Gusion of IBO, and the Striker GN-X of Gundam Battlelogue.
