A mild, courteous townsman of Beta III under the rule of Landru, who greets the Enterprise landing party in 2267 and then runs riot when the Red Hour strikes.
Bilar appears in the first-season episode The Return of the Archons. When Kirk's party arrives in the town in local dress, he is among the first to speak to them, wishing them joy and peace in the slow, contented manner of all who belong to the Body. He takes them for visitors come for the Festival and points them towards Reger's house for lodging.
At six o'clock the Red Hour begins and the placid crowd erupts into violence and licence. Bilar changes with the rest, and it is he who seizes Reger's daughter Tula and carries her off.
By morning he is calm again, with no sign of remorse. He was played by Ralph Maurer.
