What parents need to know

Parents need to know that OK K.O.! Let's Be Heroes is a quirky animated series about a kid who really wants to be a hero. It contains lots of positive messages about goal-setting, problem-solving, working hard, and friendship. Being creative and using your imagination are also strong themes.

What's the story?

OK K.O.! LET'S BE HEROES is an animated series about a young boy who wants to be the world's greatest hero. It's 201X, and the town is full of superheroes living mundane lives while fighting a handful of enemies. Young K.O. (Stephanie Nadolny, Courtenay Taylor) wants to be just like them, but when his mom and fight master Carol (Kate Flannery) remind him that it takes work to be a hero, he looks for ways to to learn how. He starts hanging out at Gar's Bodega, a hero supply shop in the Lakewood Plaza Turbo strip mall owned by level 11 hero Mr. Gar (David Herman), and befriends co-workers and lower-level heroes Radicles (Ian Jones-Quartey) and Enid (Ashley Burch). K.O. uses the time to begin learning the ropes and developing his skills. He also tries to fight bad guys, including Lord Boxman (Jim Cummings), the owner of Boxmore, a manufacturing plant that produces henchmen to help villains win the fight against superheroes and rule the world. K.O. has a lot to learn, but he's committed to doing everything he has to in order to become the superhero he wants to be. 

Is it any good?

This entertaining and positive series lets viewers follow the story of a likable kid with an active imagination and very clear goals. K.O. is sensitive and well-intentioned, but his drive to work hard and problem-solve, even after many failed attempts at being a hero, also make him a positive character.

The series features lots of clever moments, including funny one-liners and a memorable infomercial advertising Boxmore's services. These scenes may go over small children's heads, but chances are that younger tweens will find a lot to laugh at. Throughout it all, OK K.O.! Let's Be Heroes consistently underscores the fact that you aren't born a hero -- you become one.
