Ethylene (VCDF003) was born on Janaury 30, 2005, into the Commandos group to Zorilla and Aragorn, along with litter-mates: Her one brother Ketamine(VDCM0001) and one sister Benzedrine(VCDF002). Her parents were the first dominant couple the new group had. They were the first litter ever born in the Commandos. The Commandos had just formed two months prior to Ethylene's birth so there were only a few adults. Sadly Ethylene disappeared on March 23, 2005 and was assumed predated.
