Power Battle Watch Car is an animated television series produced by SAMG Animation, in association with Hyundai Motor Company, Innocen Worldwide (an in-house advertisement agency within Hyundai Motor Group) and CJ E&M.
An automobile company named JHC Motors has created high-tech toy cars for kids, WatchCars, which are miniature sentient robotic cars that have become good companions to children and adults alike.
As the undefeated and undisputed champion of the league, Kai, Jino's opponent, remains a legend.
Jino and his WatchCar Bluewill dodge various obstacles ahead to defeat him and become the new league champion.
Jino is responsible for handling the Mind Keys as Bluewill is the next-generation Watch Car.
After the match with Kai, he suffered from amnesia and Jino helped Bluewill recover.
Observant, hot-headed and sarcastic, Roy is the master of flame and his Watch Car Avan has fire-related abilities.
He is childhood friends with Ari, and has a romantic interest in her, but only found out in the episode "Lost Cupid's Arrow".
He is sensitive to physical stimuli, and also does not like to have his photo taken, due to being reserved and appearing to dislike his image.
In the "Ultra Watch Car in Crisis" episode, he saves Sona by taking in the fire attack.
However, at the Watch Car gala, it is revealed that Ari, through Mac, brought him back to life.
Although he is not a Master in the current episodes, he has played against Kai in the Watch Car Battle League (in a qualifier).
In the episode " Lost Cupid's Arrow", he and Jino were teasing Roy and Ari for going alone and made them think they were going on a date.
His weapons are Storm Gun, Crazy Missiles, Rocket Punch and the amazing Giant Fist as his Power Coin.
Ari also had a crush on Hans, one of the Watch Car Masters, but sadly broke up when she found out his true colors.
Hans is handsome and has skills, but was taking advantage of Ari, listening to her conversations, and even hurt Bluewill before their match.
At first she refuses, not wanting to ruin their friendship, but after Roy won the racing match, she then tells him she will make her decision after keeping an eye on him.
She also tends to be short-tempered whenever someone, (namely: Jino, Sophie, Maria, and Hans) mocks or tricks her, she will get into physical fights with them herself, or if someone is harassed by bullies.
Sona is Ari's Watch Car who has the ability to make anyone fall in love with her.
Kai is caring, reserved, smart, precise, ruthless, attractive, intelligent and a good player.
During one of his lowest points the Shadows successfully take control over Kai’s mind and makes him battle with Jino.
May is the loving wife of Mac, and Jino and Ari's mother, and Maria and Maru's aunt.
She makes the food and handles the emotional side of taking care of her kids and niece and nephew.
Mac is the father of Jino and Ari, uncle of Maria and Maru, husband of May and genius mechanic of watch cars.
Schmidt is the smarter, sarcastic, stronger, and nicer of the two closest followers and friends of Kai.
Ain is the genius mechanic who creates maniacal but ingenious inventions for every match he participates in.
Leo's watch car was constantly harassed and the bullies who did it blamed it on Roy by placing his ball cap there.
Leo then blamed him and attacked him causing Avan to jump in and protect him hurting his watch car in the process.
From there, he claimed he wanted to make her his, he proposed during a date, eavesdropped using a device in the ring, and steals the chip Mac made during a visit.
Sophie is an actress who rarely gets a break between shootings, script reading, campaign events, photoshoots, and the battle league.
