Enforcers were large 4-legged machines manned, originally designed by Tachyon, and operated Drophyds that served as heavy infantry in the Imperial Defense Force. They were armed with two rapid fire turrets attached to the sides of the Enforcer. Enforcers on
Zordoom Prison on planet Viceron also carried searchlights to patrol the prison for would-be jailbirds. These units would later be replaced by Enforcers galvanized in Raritanium, known as Obsidian Enforcers.
Early prototypes of these machines were originally designed with a skull like head, appearing to operate as robots rather than mechs.
The Enforcer Prototype was an early blueprint of what would later become the Enforcer. While blueprints of this machine was similar to the current model, the early prototype lacked a dome for a Drophyd to pilot, rather it contained a skull like head instead, suggesting this Enforcer was a robot rather than a mech. This early Enforcer model was originally designed by Tachyon with the aid of Lombax technology, under the request of Azimuth to build weapons in order to protect the Polaris Galaxy. Tachyon; however, had no intention of aiding the Lombaxes, rather he planned to render them extinct for what they did to the Cragmites. When Tachyon was able to obtain the Raritanium needed to buy the Drophyds' loyalty, he modified all existing models of the Enforcer by removing the skull-like head and replacing it with a dome for a Drophyd to operate.
Obsidian Enforcers were upgraded version of the Enforcers encountered on numerous first on planet Reepor in the Cragmite Ruins. They were galvanized with Raritanium, making their armor tough enough to even withstand multiple shots from the Alpha Cannon.
- Although the Enforcers were not fought on planet Kerwan (despite being clearly seen there), one was briefly encountered after a warp pad, and then hopped away leaving Ratchet to fight the Drophyd troopers on the balcony. However, if a Groovitron was deployed before the Enforcer hopped away, it would remain there and continue to attack Ratchet like normal, although it could not be damaged by means of weapons or devices.
- Another Enforcer that was seen on Kerwan could actually be killed; this Enforcer was seen hopping from building to building as Ratchet took a warp pad to the sky bridge, before firing several shots and leaping away. However, if one was to deploy a Groovitron before jumping onto the warp pad, the Enforcer would leap right into it, causing it to stop and begin dancing mid-jump and fall to its death.
- However when it falls it doesn't explodes like always, most likely because Enforcers somewhat were not supposed to be killed in Kerwan and everytime it along the other Drophyds explode when get killed or fall to the death they explode to show that they got killed, and in the case of the Enforcer it doesn't happen to deny the death.
- There's two enforcers on Kerwan that are not effected by Groovitron and don't attack the player even the Ratchet gets really near to them, what should basically happen because even Enforcers can't be killed on planet Kerwan they are affected by the Groovitron and will try to kill Ratchet as proven above, those enforcers are seen on a building shooting random shots to other buildings, Ratchet can jump right to the building that they are in but it is drastically hard.
- They are the only drophyds that are seen on Planet Kerwan but weren't faced.
- However their armor is very tough, as it can even withstand several shots from Alpha Disruptor and Negociator, so even the player demage it would've been too hard to kill, in Viceron it's different because as it's way more later the player has more new weapons and the Combuster and Fusion Bomb are clearly more upgraded.
- However they only aren't on gameplay, but there was a custscene were ratchet and clank faced one, that Enforcer was walking in the direction of them and later started to try to kill Ratchet, but that was only in cutscene.
