Marco (The Time of Angels)

Cleric Marco was a cleric, and went to the Aplan planet, Alfava Metraxis to hunt a lone Weeping Angel. His torch flickered when the Angels interfered with it, and he warned Father Octavian. He was later surrounded by the Angels with the Clerics, The Doctor, Amy Pond and River Song. (Time of Angels) Later in Flesh and Stone he sent three clerics to investigate a glowing crack in an oxygen factory. He forgot about their existence, and went to investigate for himself leaving Amy Pond alone. Because the crack was leaking time energy he was erased from existence. (Flesh and Stone)
