Reapers were mutated[source?] aliens that bore resemblance to gorillas, crocodiles, and hedgehogs. They had the ability to shoot spikes out from their backs. These spikes would be fired in an arc toward Ratchet and are difficult to avoid. They would also spit up acid at close range. They were pretty tough, so they had to take a pounding. The best way to kill one was to keep moving while using a medium range weapon like the B-6 Obliterator. Reapers were first met in DreadZone Station; Tower of Power.In Secret Agent Clank, Reapers were fought in prison. They attacked Ratchet there. In prison, there were also Elite Reapers, a bigger, elite version of the Reaper.
