Photus

From publisher blurb:

This is a new collectible RPG in a Golden Age Superheroes vein: to play, you just need any set of the playbooks, with at least one per player. Each playbook gives you a pre-made character and all the rules needed to play them or to run the game for others.

From Introduction:

Exclusive story: the Secret Origin of... Photus!
When a super-advanced robot space probe was exposed to a solar storm on a test flight in orbit, it became much more than it’s inventors had ever imagined! Returning to Earth with its newly acquired sentience and superpowers, it continues to pursue its mission: to seek out answers, collect data and perhaps solve the ultimate conundrum... can a Machine become a Man?!
