An Andorian soldier serving under Commander Shran during the occupation of the P'Jem monastery, who taunts T'Pol and later returns with Shran to Coridan.
Tholos is an Andorian of the Imperial Guard and Shran's subordinate, played by Steven Dennis. He first appears in The Andorian Incident, when Shran's squad seizes the Vulcan sanctuary at P'Jem in search of a hidden listening post.
Tholos is cruder and more openly hostile than his commander. He menaces the captive T'Pol and beats Jonathan Archer during questioning, convinced the humans are in league with the Vulcans.
He returns in Shadows of P'Jem, accompanying Shran to Coridan, where Shran intends to repay his debt to Archer by freeing him and T'Pol from rebels. Tholos takes part in the rescue and the firefight with Vulcan commandos that follows.
