Dmitri Antonov (Enzo) Cosplay

Dmitri Antonov, also known as Enzo, portrayed by Tom Wlaschiha, is a recurring character on Stranger Things, introduced in the fourth season, serving as a supporting actor. He is a Russian who is described as "smart and charming" and the father of Mikhail.
Dmitri Antonov ("Enzo") is a prison guard in Kamchatka, Russia, where the Soviets established a large prison camp.
The camp's prisoners help build a Trans-Siberian Railway and occasionally serve as food for the growing Demogorgon.
Dmitri Antonov (Enzo) Halloween Costume
Enzo works primarily as a railroad attendant and thus has no access to the Soviets' Demogorgon experiments. However, one can imagine that the Soviets trained the creature as a weapon against the United States.
Aside from his relationship with Yuri — a pilot who smuggles the Soviet soldier's peanut butter — we know little about Enzo's life. At one point he mentions being a father.
Perhaps Enzo's backstory will become more important in the final two episodes of Season 4.
