Our Hero, Phenom!

Phenom is a shapeshifter who travels the stars, disguising his identity to trick the population of every planet he visits into believing he is one of them. Until one day when Phenom wasn't around to save a world under his protection. Now the so-called "hero" must reckon with the truth: is he a noble protector? Or a fraud desperate for adulation?
