Boris

Boris is a Ukrainian landlord who owns property in Latvia. He has been described as "tough as nails."

Boris is friends with his tenant Michael and has occasionally entrusted him with his dog. After Michael informed Boris about getting shot, Boris spread the word, resulting in many people bringing him food, and threatened revenge on Michael's behalf. According to Mike, Boris has possibly listened to Michael's podcast about movies.

Bruno is Boris' pet dog. He understands the command "Сидеть" (sit) and loves baby carrots. Bruno reportedly loves to cuddle Mike when he's feeling under the weather. When Michael was recovering from a gunshot wound, Bruno joined him in bed and lay his head on Michael's chest.

Apart from his present self, Bruno has no known iterations.
