Is Blanka actually immune or resistant to electricity?

[Nkstjoa]

Just a thought, but while it's often assumed that due to his electrical attacks and abilities that Blanka is by default immune or at the very least resistant to electricity man-made or otherwise, I can't recall any actual instances or examples where Blanka demonstrated either. Putting aside electricity harming in him gameplay because of gameplay mechanics, has Blanka been shown tanking or being completely unmoved by an electrical attack in any sources (games, comics, movies, etc)?

I believe this would be useful, especially in regards to vs match-ups involving opponents with electrical attacks/abilities, which would help in determining whether or not Blanka would just be able to shake them off or may even be overloaded by them.
