Genji is one of the last of his species: an Entin. The Entin are rapidly reproducing caterpillars with a high libido and no sense of limitation. Any planet the Entin visit, they leave ravaged in their wake. They have been labeled a pest in need of extermination for eating entire continents worth of crops and terrorizing the local populace with late night techno raves. As a result, their kind has been bugsprayed to the brink of extinction.
Trying to better their ways, the remaining Entin have created the Order of Popae Monks on the fungi moon Pulvan. Fasting heavily they devote everything to their beloved deity: The Grand Space Butterfly!
Genji sinned with snacks and dirty literature however, and after repeated solitary cocoonfinements failed to make him better his ways, he was sent out on an emergency soul-cleansing pilgrimage through the galaxy.
Joining the Awesomenauts to cut back on the traveling costs of his journey, Genji has been the scourge of many a ship's pantry and is rumored to be the main reason some of the smaller more edible-looking 'naut recruits have gone missing.
