Ok, K.O.! Vamos Ser Heróis

The series is based on the pilot Lakewood Plaza Turbo by Ian Jones-Quartey, released in 2013 as part of Cartoon Network's Summer Shorts project, and the full series was only confirmed nearly four years later, in March 2017.

According to Jones-Quartey, the Dobbin Center served as inspiration for Lakewood Plaza, while Boxmore represents Columbia Crossing, a shopping center opened in 1997.

Each episode took about nine months to be completed, from start to finish.

When hiring the team, Jones-Quartey avoided relying solely on a network of trusted contacts, prioritizing diversity and making several open calls, contacting people by email based on their previous work.

Unlike most animations, which are drawn with ink on paper and then scanned for colorization, OK K.O.! was drawn in pencil on a light table, being colored digitally on a layer below the transparent line to preserve the hand-made appearance, an inspiration that came partly from the first season of The Simpsons.

The series' opening sequence was storyboarded by Japanese artist Hiroyuki Imaishi, co-founder of Studio Trigger.

The series had a crossover episode called 'Crossover Nexus', bringing together characters from OK K.O.!, Steven Universe, Ben 10 and Teen Titans Go!, as well as a crossover episode with characters from Sonic the Hedgehog titled 'Let's Meet Sonic'.

The series presented striking LGBTQ+ representation, including two married homosexual couples (the villains Lord Boxman and Professor Venomous, and the heroes Joff and Nick Army, who married in the final episode), as well as characters confirmed by the creator as bisexual, pansexual or non-binary, such as Enid, Venomous, Boxman and Gregg.

In August 2022, the series was removed from HBO Max as part of the Warner Bros. Discovery merger, without the creator Ian Jones-Quartey being informed of the reason for the removal.
