Some of his lesser used last names include Boris Perkyshitz (Perkyshitz Family) and Boris Green. (BrentAnimate) He is the husband of Doris (Ms. Martin in some series) and the father of Caillou and Rosie, and, in some series which include extraneous Anderson family members, Cody, Daisy.

Personality (Caillou Gets Ungrounded)

Boris is the deuteragonist of CGUG. In most cases of Caillou Gets Ungrounded, Boris is a nice, caring, and loving father of Caillou, and dislikes/grounds Rosie. However in some users' series, such as Tbone Animate's series and DGGHater2004's series, Boris also likes Rosie. Boris' personality is quite bland in this series.

  • Boris (My Life with the Andersons): This interpretation of Boris was a renowned child abuser. In 2017, he was sentenced 40 years to life in prison. In 2018, he broke out of prison and went on to assault and maybe kill Alfie Naylor. He was shot and pronounced dead that same year.

  • Boris is most infamously known for committing a series of mass murders in GoCity back in 1992. First, he aimed a missile at a government building, killing 168 people (including 19 kids) as a result. Two days later, he snuck into his old elementary school and killed 28 more kids. But thanks to the overused excuse known as GoAnimate logic, nobody actually died and magically came back to life in the next episode. It turns out that they only had minor injuries.
  • Boris used to work as a daycare teacher who respected the kids he taught, he would also accompany the kids while they sing by playing the piano, or guitar. However, he got fired after his boss found out about the way he was treating his own kids.
