Eight book collections of comic book stories have been published so far: The Whole World's Crazy, What Makes You Happy, Superheroes, When the Past is a Present, The Tweenage Guide to Not Being Unpopular, True Things (Adults Don't Want Kids to Know), The Meaning of Life...and Other Stuff, and Her Permanent Record.

(Gathering of Awesome Super Pals), Reggie Grabinsky is a fun-loving, silly guy with a loose grasp on reality.

At one time Tanner was a pop rock princess who ruled the charts, but she retired for mysterious reasons and now lives the quiet life in small town PA.

She uses care and caution when approaching potentially unsettling moments, like telling Amelia that they are moving (again) and breaking the news that she is going out on a date.

Amelia’s dad also loves his daughter unconditionally, but struggles to be an active part of her life, given his infrequent visits and the miles that separate them.

A bit depressed from the collapse of his marriage and the dwindling popularity of the company he promotes (he’s marketing director for Softee Chicken, a once-popular kids’ franchise), he still maintains a semi-cordial relationship with his ex (that is when he doesn't think Amelia is around).

He was injured in a fall at the climax of "True Things" and reappears in "Her Permanent Record" in which he has not completely recovered from his injuries after he broke his leg.

She suffers from a severe case of ventricular septal defect which eventually causes her to move to California to see a specialist in "Superheroes", but she sends Amelia a letter years later to tell her that she survived the operation.

Ninja Joan Driscoll Originally known to Amelia only as a member of the rival Park View Terrace Ninjas, Joan became closer friends with Amelia and Rhonda after her father, a Captain in the US Army, was deployed overseas for a year.

Joan’s tomboy tendencies and a quick wit make her a natural fit in Amelia’s small group of friends.

He is also a member of G.A.S.P., although, he doesn't seem to have an alter ego and simply wears homemade bat wings that he believes enables him to fly, which is proven wrong when he attempted to ambush the Park View Terrace Ninjas and fell.

Mary Violet/Ultra Violet A goth girl who appears to be Catholic and described as a "Cabbage Patch Kid that threw up".

is a superhero group that protects the neighborhood from whatever happens to be bugging leader and founder Reggie Grabinsky, such as Ninjas and the Legion of Steves.

Founding members are Reggie (Captain Amazing), Amelia (Princess Powerful), Rhonda (Ms. Miraculous), and Pajama Man (Kid Lightning).
