Chapter 4 is all about Freedom City's heroic teen residents. Claremont Academy, the setting's stand-in for the Xavier School and home of the Next-Gen, is described in detail. Stats for various staff members are given, and a list of prominent students is also found herein. Instead of actually statting the kids out, though, general guidelines for powers and skills are given, allowing player or GM to stat said students as PCs or NPCs. After that, the Alterniteens are presented. A group of dimension-spanning teen heroes who crash at Claremont, the Alterniteens are a fun addition to an already fun setting. Hands down, my favorite of these is Whoop-Ant - imagine Hank Pym as a hyperactive teenage boy and that pretty well sums up the character. This chapter concludes with some of the secret history of Claremont (and the FC setting as a whole) providing ideas for any kind of Freedom City campaign, not just ones focused on those meddling kids.
The art in Hero High, even given M&M's usual standards, is phenomenal here. All the artists tapped for this book deliver an engaging, light-hearted style that's a perfect fit for the subject material.
Overall, Hero High is a phenomenal supplement for the M&M game system, and darn good book as far as rpgs in general. Simply put, Hero High makes the grade with honors!
