Goth-Girl, occasionally violent
Part of the small goth clique at Independence High School, Helena is the most in-your-face of the group and hence the most prone to receiving detentions and other punishments. It was after one too many clashes with the administrative staff over appropriate hair-colours for school and Mr Althorp receiving a black-eye (Helena maintains he grabbed her shoulder and shook) that Helena was made to join the Breakfast Club.
Whilst she remains very much a member of the goth clique, she has opened up somewhat to the other members of the club, though she and Jonah clash often. [Matt, feel free to say otherwise… it just seems likely to me.]
