Dimitris was one of the Athenian soldiers who were carting a statue of Athena to Hektor's blacksmith forges to be melted down in 410 BC. Calidora tried to stop them, but Captain Alexios brushed her aside and they kept on going.
When Zeus activated the many monsters disguised as normal objects in the town, Dimitris and the soldiers fought the cyclops. Dimitris was surprised when Alexios killed the beast by swiping his sword through it, when in reality the Doctor had switched the creatures off by use of Calidora's talisman.
When Ares attacked, Dimitris fought but collapsed when Alexios was killed. Later, he sent off the Doctor, Amy and Rory after Rory successfully defeated Ares. (COMIC: The Chains of Olympus)
