As I understand it, a protege, who hangs out and gets into trouble with the hero, all the time -Bucky, Robin, Sandy, etc -is typically called a sidekick, in superhero comics.
A good example of a famous sidekick, who wasn't her superheroic partner's protege, was the infallible Etta Candy...the Golden Age one. Pistol-packing, fearless cowgirl Etta was Diana's first true Wonder Girl, even without Amazon lineage, superhuman powers and a Cosmo figure, ..and every subatomic universe Wonder Woman jumped into, Etta was right behind her! WW creator, Dr. Marston, didn't present Etta as being limited in her abilities or ambitions, by her being morbidly overweight or appearance, but, instead, showed her to be every bit the action partner, Robin or Bucky was, ..and she was more of a partner, than Donna or Cassie have ever been. No contest.
PERFECT IMPERFECTION: WHY LESS WILL NEVER BE MORE, WITH WONDER WOMAN'S ETTA CANDY!
Anyway, while Yara is salty and fun, I think writers have to watch it with her, because some of us have Diana on such a high pedestal. Don't tease the Great and Holy Diana. LOL
