>>93538331>villain implies she is evilShe is evil by the moral standards of the show. She outright does evil laughter, plots and schemes and serves as the primary antagonist to Arnold and the others most of the time.
The only episodes where she isn't villainous are ones where she's with her family that make her look lovely by comparison or if its a "Helga breaking into Arnold's home to stop him finding out her secret" episode.
Her image that she presents to the other characters is that of an harsh bully, she presents an image to herself of a maniacal evil genius but has that rubbing alongside her "true nature" as a erudite softie.
