The son of a Russian senior bureaucrat, Biff has received special education in wrestling since he was a child. He practices an assortment of martial arts (sambo, karate, etc.) and has won many championships. Disliking showmanship, Biff prefers executing his attacks with concentrated power and playing out every move in his head. At one time, he was a student at Mike Haggar's gym, along with his friend/rival and fellow wrestler Gunloc. It upsets him greatly that some individuals consider wrestling to be fake.
- The Hyper Cannons were a CWA tag team comprised of Biff Slamkovich and Gunloc. The team is mentioned in Hugo's ending in Street Fighter III 2nd Impact when paired with Ryu, Necro or Gill.
- Biff's quote when losing alludes to the possibility that he was once a training partner and/or is friends with Zangief: ("Comrade Zangief was right! You all play cheap!").
- He is modeled after Kerry Von Erich and is also believed to have been one of the influences in a later character design for Alex from Street Fighter III.
- While the game says that Kiev is in Russia, it is actually located in the former Soviet republic of Ukraine.
- His favorite attack is Head Rocker.
