For the Evulz: Despite the stereotype, the other villains generally had some kind of motive for whatever harm they were doing to the planet.
Anthropomorphic Personification: Of war and destruction.
Weaksauce Weakness: Pollution, hate and Hitler's Death Glare.
Save the Villain: Many times, occasionally Lampshaded and according to Dr.

Good Hair, Evil Hair: His green mullet, which surprisingly, he pulls off.

The episodes before then weren't changed, and the first episode has her saying to Wheeler, when he calls her Russian (can't remember exactly what he said) "SO-VI-YET!" as close to his face as possible to make it clear.
Before the Soviet Union fell, the opening would say "Linka from the Soviet Union", and then after it fell the writers changed it to say "Eastern Europe".
The evidence suggests she's not actually Russian, or at least her family isn't she was a Soviet citizen, though.
