So outside of a couple of *bad examples (assuming you know or even care about comics) which are a tiny little niggle that quite frankly doesn't matter on the whole, this is an excellent product even outside of it's intended usage of the creator's settings. It's designed for D20 Modern, but it can be adapted to other versions and quite frankly, I'm going to be using it as an idea mine for another game system all together. And it's a steal at a sale price of FREE. If you want some ideas for superhero style sidekicks, this is a great little PDF.
The only reason I'm taking a mark off is that it's tied (mechanically) to D20 Modern, which frankly, was a bad system for what it wanted to do.
*(The only issue is that he uses Kitty Pryde (X-Men's Shadowcat) and Jubilation Lee (X-Men's Jubilee) and claims that they were 'petite'. Kitty Pryde started off at 13 at about 5' 2" and ended up being 5' 6" as an adult, she was never petite. And Jubilee ended up at 5' 5" which is average for an American woman, and tall for her Asian background. Not to mention that she got turned into a Vampire that magically gave her the chest she always wanted. But again, as a Comic Nerd, little things like that bother me, but not enough to remove marks, simply because I know what the author was trying to go for.)
