Mica High Students
Sure, we're talking about hundreds of kids here, but for the most part, the whole student body at Mica High acts as one character. There are very few leaders in this group, and when one does emerge, they follow devotedly. First, they are led by the intensely dull Wayne. Then, they follow Stargirl's example.
The lemming-like behavior of the student body helps Stargirl to truly stand out. But it also poses a Very Important Question: how much of our identity is really left up to us, and how much is just a mirror of everyone else around us?
