Milo is an Alien male kid student at Monster Kids Academy.

Milo moved with his Dad, Mr. Goldar, to Planet Prinwerk for job. Milo will be attending his new school called “Monster Kids Academy”, a monster in training school made up of other Monster children.

Along with Dad, Milo also has his trusty pet dog Cyclops.

Milo meets Julie Ghost, a quiet young girl ghost on his first day of school, and the rest of the story between them is history in the making.

Vince is a Vampire male student at Monster Kids Academy. He becomes best friends to Milo on the first day of school, helping him overcome the nasty Woolfe brothers and their antics. Vince is a hyperactive, funny kid with a very random attention span.

Julie is a ghost female student at Monster Kids Academy. She is a very smart student and best friends with Samantha Witch. When she gets upset at people, or nervous, she has a habit of going invisible like a ghost and leaving the scene. She is intrigued by Milo because he is new to the planet.

Timber Adams, also known as “Dry-Rot”, is a zombie male student at Monster Kids Academy.  His nickname is “Dry Rot” as a nick name, cause pieces of his body (arm, foot, leg) occasionally “fall off” like loose Lego’s, a trait of most zombies.

He becomes friends with Milo and Vincent, after helping Milo overcome the bully Woolfe brothers on the first day of Grade 6.

A mummy kid, Bobbie is the oddball from the whole crew, as he does not speak at all because of his mummy bandages. So he just writes everything on a portable chalkboard he carries. It is also rumored that Bobbie is a dancing machine and knows all the latest moves.
