The reader is a orphan boy bouncing through family's, his most recent one being Grace Bloodgood, aka, the Headless Headmistress of Monster High. Because of this he goes to monster high, but is obviously not the very popular fellow. While most won't attempt to physically hurt him, they still do insult him, atleast some do, there are still people who know the limit of what they can say, such as Toralei, who is a Orphan as well, so she doesn't bother him. He one day gets chased by some guys from the normie school who are aware of who his current foster mother is, so he runs and escapes in a vacant subway car, yadda yadda yadda, he gets the powers like in the movie or comic book.

He has a pet Dimorphodon. (As big as a Pikachu would be)

Archaeopteryx (average bird size)

And Microceratus.

Abby has a pet Mammoth and Toralei has a pet sabertooth tiger. So who says dinosaurs and the like are extinct.
