“If you’re a kid with powers, then where’s the place to be? You belong at “Hero Elementary!”

Four young students take the cartoon stage as superheroes-in-training on the kids’ TV series “Hero Elementary.” This animated show on PBS Kids is free for millions of children to watch across the globe. In each half-hour episode, uniformed student superheroes practice their superpowers and learn regular skills in day-saving scenarios at their special elementary school for super kids. 

“Who’s the crew who knows what to do?!”

Known as the Sparks’ Crew (see details below), the four main characters use their superpowers to solve youth-level mysteries around Citytown — mysteries that serve as lessons taught by their teacher, Mr. Sparks. The group is challenged to use STEM skills, especially when they realize their superpowers can’t help them completely. In the segment titled “The Sweet Smell of Success,” for example, the crew learns about using their five senses to investigate a mystery.

This article will go into detail about the main characters of the Sparks’ Crew, as well as other supporting characters on the show. Parents can read all about what their children will be watching when tuning into “Hero Elementary.”

Who Are the Main Characters of “Hero Elementary?”

“Sparks’ Crew to the Rescue!”

The show stars a delightful group of four ethnically diverse cartoon students, each with their own unique superpowers.

Lucita Sky (Voiced by Veronica Hortiguela)

Lucity Sky in Hero Elementary

“Come on, team!”

Lucita Sky is the Hispanic-American firecracker and leader of the Sparks’ Crew. She has the superpower of flight, but because she hasn’t mastered the skill yet, she sometimes needs help when she gets stuck. But this occasional hiccup doesn’t stop Lucita from flexing her superpowers. Lucita has an empathetic personality and she always looks for ways she can help others.

Lucita is allergic to coconut. In the “Sara Loses Her Snap” segment, she accidentally eats a coconut bar and temporarily loses her superpowers. Another fun fact about Lucita Sky is that she is bilingual in English and Spanish, often switching between the two languages when she speaks.

Benny Bubbles (Voiced by Stacey DePass)

Benny Bubbles in Hero Elementary

“Bubble up!”

Part of the Sparks’ Crew, this little Greek-American blondie is known for more than his freckles — he makes bubbles, and lots of them. Benjamin “Benny” Bubbles uses his “bubble up” superpower to create bubbles for various reasons. In the segment, “Hero Hit Parade,” Benny saves his friends and himself as they fall from a great height by shouting, “Bubble up!” The four heroes are suddenly enclosed in Benny’s bubbles, and they softly bounce on the ground, safe and sound. 

Benny also uses his bubble powers to create bubbles on his feet and bounce around, jumping at tall heights. In the segment, “The Blob,” however, Benny discovers that his bubbles don’t work against clay. They do work on water though, allowing him to create rafts for floating.

 Benny Bubbles is the loveable, goofy, animal lover of the group. He is closest to the class pet, Fur Blur, and is often driven to help animals in distress.

AJ Gadgets (Voiced by Jadiel Dowlin)

AJ Gadgets in Hero Elementary

“Use super tools to save the day!”

Arnold Jasper “AJ” Gadgets is the Sparks’ Crew’s master of technology. AJ is an innovative African-American boy who is constantly pulling out a cool gadget to help solve the group’s latest challenge. And his superpower is “thought projecting!” AJ is able to shout this short phrase to automatically project an image of his thoughts in front of people to view.

AJ often uses a backpack jetpack or jet shoes to fly around during an investigation. He also keeps an extendable robot hand in his backpack to help him throughout his day.

Another interesting characteristic about AJ is that he has autism. In the segment, “AJ’s Extra Superpower,” he talks about his experience with having autism. Lucita encourages him to see this as an extra superpower, illustrating the show’s goal to foster empathy for all people.

Sara Snap (Voiced by Stephany Seki)

“Teleport in no time flat? Sara Snap can, just like that!”

Sara Snap rounds out the fully diverse Sparks’ Crew as a Japanese-American student in pigtails. She can teleport at the “snap” of her fingers, and though she may be a tiny little girl, she is mighty powerful. 

Sara is the only member of the crew who has multiple superpowers. In addition to teleportation, Sara also has super strength. In the segment, “Super Lift,” she helps her classmates learn how to lift heavy objects, even without super strength. Sara’s other superpowers include being able to shout super loud and jump super high!

Mr. Sparks, the Teacher (Voiced by Carlos Díaz)

Mr. Sparks in Hero Elementary

“Remember to use your Superpowers of Science!”

All four main super kids are in Mr. Sparks’s “Sparks’ Crew” class at Hero Elementary. Mr. Enrique Sparks is a bilingual science enthusiast who encourages his young hero students in English and Spanish to use both their powers and their brains (the Superpowers of Science) to solve problems. He is also the narrator of the show.

No one knows if Mr. Sparks has superpowers himself. While the students are learning to hone their superpowers, Mr. Sparks never displays any supernatural abilities, always focusing on science and real-life skills when teaching lessons.

Fur Blur, the Squeaky Hamster

“Squeak, squeak!” 😃

Also known as “Sparks’ Crew Hamster,” Fur Blur is the furry class hamster who plays a major role in the students’ day-to-day activities. As explained during the episode, “First Day of School,” Fur Blur was adopted by the crew after the students succeeded in their first mission together — to save the Citytown Animal Shelter. 

When she’s not perched on Mr. Sparks’s shoulder or one of the students, Fur Blur is constantly making herself part of the action. She can run super fast (hence the name Fur Blur) and although she can’t speak, only squeak, she can also communicate by sharing her thoughts through emoji clouds above her head.

Other Recurring Characters of “Hero Elementary”

Petie is the other member of Team Tornado. With red hair and heat-generation melting superpowers, he is the hot to Freeze Louise’s cold.

Athletica, Superheroine
(Kristin Fairlie)

Pronounced ath-leet-uh-cuh, Athletica is a famous superheroine who has the adoration of the Sparks’ Crew.

Captain Bounceback, Superheroine

Dr. Inventorman, Superhero
(Martin Roach)

Most admired by AJ Gadgets, Dr. Martin Inventorman is a famous superhero known for his inventions, comic books, acting career, and of course, his super ability to fly.
