Lieutenant Yoomba is the chief of security on the USS Chichen Itza. He is a Tellarite. He goes beyond merely insulting others and has played numerous pranks. He was born in 2350 in Shirgat, Tellar. His first words were (to his mother) 'You smell like rancid turnip' He was babysat by none other than the future counselor of the Chichen Itza, Garwy, who at 350 years old was more than capable of babysitting him.
