|Birthplace||Ravnica City, Ravnica|
Doctor Otrovac was a vedalken who served as a personal messenger of Momir Vig of the Simic Combine when dealing with high-ranking representatives of other guilds, such as guildmasters. He wore a cytoplast enhancement on his neck, one that allowed him to communicate in real-time with Vig. He was tasked to offer the Golgari guildmaster Jarad the possibility of using cytoplast to boost the Golgari workers' performance. The offer was rejected several times, despite additional offered benefits from the Combine.
The name "Otrovac" is derivative of the Serbo-Croatian word otrovan meaning "poisonous."
