Hudak was an Antaran teacher in xenomythology who was doing research on Xantoras when a xenophobic group overthrew the government in early 2153. Along with all other aliens, he was forced to leave the planet as a result. He suffered heavy radiation poisoning when the reactor of the transport he was on ruptured and was brought aboard Enterprise NX-01 for medical attention, together with several other passengers. Although he was dying and Enterprise's medical technology allowed for a full recovery, he refused medical treatment from Phlox, a Denobulan doctor. The Denobulans had fought long wars with the Antarans, who considered the Denobulans to be their enemies.
