Zangief's Weird Adaptational Villainy

The variations between the adaptation (or remake) vs. the video games really do differ a lot, right? A good example is how Zangief who's a HERO in canon ends up becoming a villain in non-canon Street Fighter media. How he appeared as a villain varied from adaptation to adaptation.

The failed Street Fighter movie which made Guile the protagonist over Ryu made him a naive villain. He had no idea that M. Bison was REALLY a bad guy. He had his funny moment when he said, "Quick! Change the channel!" when a truck was about to hit their base. He had no idea that Shadaloo was a villain organization. Ironically, Balrog who is a VILLAIN in the games was a good guy in the movies. 

After the failed movie - two more series followed. One was the Street Fighter II V cartoon and the American-exclusive Street Fighter cartoon. Zangief played as a dumb muscle antagonist in both versions - something he doesn't become in the Anime movies. 

Why did this happen? There hasn't been a clear reason to make him from hero to villain in some adaptations. I feel like there was still some animosity at that time between the USA and Russia during the 90s. Though that's just my hunch as to why this happened.
