History[]
Scooby Doo... Where Are You! (Charlton Comics)[]
Boris, a long with his incompetent partner Igor and several other spies were watching the Mystery Machine drive on by the road to the research center after Daphne's Uncle Verner called them about a concern about spies. Before he could make a plan, Igor tried to throw a bomb at the center, but he interrupted him telling him not to throw it, which ended up blowing up in Igor's face.
He took a look back at the gang, and went with his plan to sneakily infiltrate the center via disguise. In a quick spin he turned into a soldier to see the credentials, which Daphne showed him and explained about the situation about spies, then quickly silences her with knockout gas before spinning again and turning into Daphne.
He then tried to infiltrate the nuclear research center along with the gang, in the guise of Daphne Blake. Scooby-Doo scented the man under his disguise and exposed him after causing an irritation, which led to him chasing Scooby, but it eventually led to his capture when they crashed into an outdoor pool, and he was taken by authorities.

Boris revealed.
