The Agents of Doom are small androids dispersed from the Glove of Doom and serve as a weapon product manufactured by Gadgetron, featured in Ratchet & Clank and its re-imagined re-release, Up Your Arsenal, Size Matters, also making a cameo in Secret Agent Clank. The Agents are dispensed from DoomEggs launched from the Glove of Doom, and act as kamikaze explosives, running towards an enemy and exploding on contact.
The Glove of Doom can be upgraded to the Gold Glove of Doom in Ratchet & Clank, and in the re-imagined release, it can be upgraded to the Apocalypse Glove, and later to the Omega Apocalypse Glove in challenge mode once the holocard set is complete. In Up Your Arsenal, the Agents of Doom can be upgraded to the Agents of Dread, and later to the Mega, Giga, and Omega Agents of Dread in challenge mode. In Size Matters, it can be upgraded to the Agents of Dread and Titan Agents of Dread in challenge mode.
Ratchet & Clank
The Glove of Doom may upgrade to the Gold Glove of Doom for 10,000 bolts and 4 gold bolts. This could first be purchased in the gold weapons room on the Gemlik Base, and later accessed in challenge mode in the gold weapons room reached with a teleporter at the Tobruk Crater, Novalis.
In Qwark's retelling, the Glove of Doom was one of the later weapons Ratchet obtained. It became available when Ratchet entered the Deplanetizer, for 35,000 bolts. Ratchet could upgrade the weapon using Raritanium upgrades, and it upgraded with use to the Apocalypse Glove, improving its capabilities and damage, while not drastically changing its function. These Agents of Doom with the Apocalypse Glove used a jetpack to fly towards enemies and attack them. Additionally, Captain Qwark used his own Agents of Doom against Ratchet on the Deplanetizer, during "Stop Captain Qwark", which were spawned from a blarg generator thrown from his own Glove of Doom.
In challenge mode, Ratchet's Apocalypse Glove may upgrade to the Omega Apocalypse Glove for 300,000 bolts.
Up Your Arsenal
Agents of Doom first became available for purchase once Ratchet reached the Annihilation Nation, Station Q9. They upgraded to the Agents of Dread with use. Once entering challenge mode, the Mega Agents of Dread may be purchased for 660,000 bolts (594,000 with a discount), and then upgraded to the Giga and Ultra Agents of Dread.
The Agents of Doom were available from planet Ryllus for 25,000 bolts.
Secret Agent Clank
The Glove of Doom in the original Ratchet & Clank itself is a black glove that fits onto Ratchet's hand, with a green circle in its center. In Up Your Arsenal and Size Matters, the Agents of Doom is a red, bulkier glove with silver fingers, which retains the central green circle.
The Agents of Doom robots are short, with a large circular head, blue eyes with the left eye larger than the other, and sharp teeth. In the re-imagined Ratchet & Clank, once upgraded to the Apocalypse Glove, the Agents of Doom fly with a blue jetpack towards enemies to attack them before self-destruct, and upon reaching contact with an enemy exploded in a blast radius that could damage nearby enemies. When upgraded in Up Your Arsenal and Size Matters, the Agents of Doom can also carry weapons on their shoulders, and fly jetpacks.
The Agents of Doom are deployed to self-destruct when coming into contact with an enemy, or to bite them first repeatedly to damage them. This means that the Agents of Doom (in earlier levels) are best for fighting small groups of medium or larger enemies, as their damage could be split between multiple enemies or concentrated on a single enemy with no major cost. They are also good at destroying enemies hiding behind cover. However, when upgraded in Up Your Arsenal and Size Matters, they become more versatile once upgraded, by adding ranged attacks.
In the original Ratchet & Clank, the Glove of Doom was strong against most larger foes on the ground and capable of dealing with most threats, but useless against flying enemies and could be destroyed by enemy fire. In the 2016 re-imagined Ratchet & Clank, the Glove of Doom's Agents have a greater explosion radius when self-destructing, and when upgraded to the Apocalypse Glove, are able to fly with a jetpack towards enemies, making them even more broadly useful against most enemies and groups, particularly to supplement Ratchet's damage. In Up Your Arsenal and Size Matters, the Agents of Doom are not situational when upgraded, as they become far more versatile, and useful against any enemy.
In Up Your Arsenal, the Agents of Doom fill the same function at V1, in that they hunt out and destroy enemies on ground. At V2, they gain laser cannons, which they will fire at enemies until they run out of ammo, at which point they will self-destruct the enemies as usual. The V3 upgrade improves the rate-of-fire of these cannons. At V4, the Agents gain jetpacks. The first set of V4 Agents deployed will hover around Ratchet and protect him, functioning as synthenoids, until out of ammo. Any newly deployed Agents will act as normal on the ground, or replace those that ran out of ammo while in hover mode.
When upgraded to Agents of Dread at V5, the Agents deal far stronger nuclear explosions upon self-destructing, and their laser cannons are replaced with more powerful missile launchers. The Agents must be upgraded to remain useful, as at earlier levels, their damage drops off compared to other more versatile weapons such as the Annihilator or Disc Blade Gun. Conversely, the fully upgraded Omega Agents of Dread has 12 ammo and a power of 12,000, which is theoretically more powerful than the RYNOCIRATOR.
In Size Matters, the Agents gain bomb launcher cannons at V2. At V3, these cannons instead launch stronger energy blasts. As Agents of Dread, the Agents now feature a jetpack, and the first set deployed will fly around Ratchet and protect him.
In the original Ratchet & Clank, the Ultra Supreme Executive Chairman Drek-Mech throws out Dark Gadge-Bots to attack Ratchet, resembling larger Agents of Doom. In the 2016 re-imagined release of Ratchet & Clank, Qwark sends Agents of Doom to fight Ratchet from a blarg generator on the Deplanetizer.
In Secret Agent Clank, Agents of Doom appear as enemies used by the final boss, in which Robo-Ratchet may deploy them. They are easy to destroy but also easy to avoid, as running away works as well. This is helpful for the 'A Pretty Good Likeness' skill point.
Behind the scenes
In the Insomniac Museum in Going Commando, a cut weapon known as the "Hounds of Doom" can be found, which have a similar appearance to the Agents but with the shape of a dog. The Glove of Doom is also left within the game's files, though firing it does not throw out any Agents and the weapon's texture is glitched.
