The Chikarri were sapient rodents from Plagen. They were a sentient species with mammalian features. They had two arms and two legs with a long tail which made them very agile on their feet. Chikarri tended to be very inquisitive in nature. They had been known to disassemble pieces of technology quickly and rapidly discern its function. They then adapted the new technology to their own. This knowledge of a wide range of technology made them valued as mechanics and technicians.
