Ivan is a minor antagonist in Brickleberry, only appearing in the episode "Saved by the Balls". He is a Russian mobster from an underground crime ring who sells illegally grows and distributes marijuana in Hazelhurst. He is the only son of the mafia's leader, Nikolai and worked with the team up until he was murdered by his dad for not telling Steve Williams "Bless You" when he sneezed.
In "Saved by the Balls", Steve and Denzel Jackson found a room full of cops who were just killed by the mafia. When they were ready to get out of there, Ivan came by with some of the other members of the mafia and held them at gunpoint. Their leader, Nikolai came up and assumed they were his new growers and hired them to work for their team. They went along with the act so they wouldn't get killed by Ivan and the other goons.
Steve worked with Ivan to grow some marijuana in the garden for the Russian mafia. After stealing Malloy's testicles and using the juice to water the seeds, the marijuana plants grew to be as tall as the redwood forest. Ivan was so proud of his work with Steve that he partook in some of the weed and smoked it for himself.
Shortly after Steve was introduced to the mafia, Ivan didn't last very long because of how he treated his new teammate. When Steve sneezed, Ivan didn't say "Bless you", which meant that Nikolai had to to take care of him. Nikolai pulled a gun on Ivan out of nowhere and shot him dead right there on the spot. Nikolai was Ivan's own father. Ivan didn't even react when he was about to get shot. He just stood there with his face hanging out and let himself get shot to a bloody death.
