Blarg generators are enemies in Ratchet & Clank and the 2016 re-imagined game. They are blargian robots used by Drek Industries that spawn other small robots, including robomutts, scoutbots, and chompers (as well as bladeballs in the re-imagined game). They were encountered on planets Kerwan, Batalia, Gaspar, and others.
Ratchet & Clank
Blarg generators were first found in Metropolis, Kerwan, spawning robomutts during "Visit Al's Roboshack" and "Explore the rest of the city." Later, they were fought, spawning scoutbots on Batalia inside Fort Krontos during "Explore the walled city," and again in the Blarg Depot on Gaspar during "Find the Pilot's Helmet," spawning chompers. Finally, generators spawning scoutbots were fought in Gorda City, Oltanis during "Search the destroyed city."
Blarg generators were fought in similar contexts. First, they were fought in Aleero City, Kerwan, during "Find a route to the Hall of Heroes," "Find a train to the Hall of Heroes," and on the grav-train during "Ride the train to the Hall of Heroes," spawning robomutts. Next, they were fought in the Blarg Research Outpost on Gaspar, spawning chompers and bladeballs during "Fight the Blarg." Next, they were fought at Fort Krontos on Batalia during "Get to the Turret," spawning bladeballs, and again in Skorg City, Quartu, spawning bladeballs during "Infiltrate the factory" and "Investigate the factory." Once again, they were fought on the Deplanetizer, spawning bladeballs and chompers in "Disable the Security System" on the first visit and in the Gadgetron Headquarters on Kalebo III, spawning bladeballs in "Find the Focus Lab." Finally, Captain Qwark threw his own blarg generator, spawning his own Agents of Doom against Ratchet during "Stop Captain Qwark."
Blarg generators are shaped like a round, black, white, and yellow barrel, with a yellow lid from where small robots are released. They are held up by three small legs, and have a red antenna on the side.
In the original release, the generators will spawn either robomutts, scoutbots, or chompers, and are completely immobile. When spawned robots are destroyed, they will spawn new robots to replace them (unless still contained in the Suck Cannon, in which they will only spawn new robots after fired from the cannon). They are easily destroyed in a single hit, and should be destroyed first to prevent them from spawning more enemies.
In the 2016 re-imagining, generators are mobile, and their legs will sometimes extend and cause them to run away. They spawn either robomutts, bladeballs, or chompers, and are tough and can sustain heavy damage. It is often best to focus on the generators with heavier weapons after defeating nearby enemies with a weapon such as the Proton Drum or Pyrocitor. Alternatively, using Mr. Zurkon can allow Zurkon to kill nearby enemies while focusing on the generator. If their evasion becomes problematic, the Groovitron can stop them from running while they are destroyed. Qwark also spawns his own blarg generator with Agents of Doom, though the strategy against this is the same.
