- “ Oh no! Thank goodness that wasn't little Susie! ”
- ―MegaCorp commercial announcer, after the head of a Test Dummy was blown off by a defective toaster [GC]
Test Dummies were robots manufactured by Gadgetron Corporation and MegaCorp to test new products on, including weapons. In the original game, Test Dummies first appeared at the Gadgetron Site on planet Kalebo III. There, they acted as regular enemies and attacked Ratchet and Clank with weapons, including the Bomb Glove, the Pyrocitor, and the Walloper. They were also Ratchet's competitor racers in the Gadgetron Site's hoverboard race.
In Ratchet & Clank: Going Commando, the Test Dummies sometimes made cameo appearances in the movies that Ratchet and Clank viewed on the various planets of the game (including the commercial for the MegaCorp Testing Facility).
In Ratchet & Clank: Up Your Arsenal, they appeared inside the VR Deck as enemies. Ratchet would fight several rounds with the dummies to earn prizes as well to test new weapons on aboard the Starship Phoenix.
