My superhero is Reticular Formation Substance P. 

I'll call him Alarmclock! Because the Reticular Formation is involved in sleeping and substance p allows for perception of pain, this cool little superhero would wake up sleeping AP students!

Alarmclock began as a young, tired man. As a child he used to always oversleep and would show up to school late. Sick of this problem, he sought to help other AP students in waking up on time. When these kids oversleep, Alarmclock would seek them out and give them a little pain in order to wake up on time!

He uses his powers for good, ensuring that all AP students can wake up on time!
