For the Players' section/chapter: basic character building.
Start with your (disads)complications. Many superheroes are known more for this than anything else. Define who you are, what you believe in. These are the adventure hooks your GM uses to get you involved in the adventure, to make it personal to you. What is your name, your personality, your costume, your reason for being a hero?
I have a bucket method I've suggested for brand new players to build characters from. Ten buckets of points to give you a rough start to your build. Give each bucket a number of points, and a label of what you want to build from it.
Super strength, super speed, some other superior characteristic...bucket.
One bucket for the "extra" characteristics to round out the rest of your stats.
A bucket for your offensive capabilities. Another for your defenses. Want to be really powerful at one or the other? More points in the bucket.
Don't forget a bucket for movement. Can't forget one for skills.
Is there something that your character is known for? Their niche, their calling card, their signature ability? There's a bucket for that.
Save a bucket for the "candy", the little cool things you might want but overlook or leave out if you overfill the previous buckets.
Now you've got buckets of points, and an idea what to spend them on. Crack open the book, and see what those points will buy/build you!
