The show is based on Jones-Quartey's pilot Lakewood Plaza Turbo, which was released as part of Cartoon Network's 2013 Summer Shorts project.

[5] The opening sequence was storyboarded by Japanese artist Hiroyuki Imaishi, co-founder of Studio Trigger.

Alongside him are his best friends and co-workers Radicles, a narcissistic alien, and Enid, a levelheaded big sister–like ninja, as well as other heroes who work in the area.

Let's Be Heroes, Cartoon Network's Chief Content Officer Rob Sorcher hinted many times that it would become a full series.

[17] In September 2017, Jones-Quartey said that Dobbin Center was the inspiration for the Lakewood Plaza, while Boxmore represented Columbia Crossing, a strip mall which opened in 1997.

[18] The show was traditionally animated in South Korea by Digital eMation and Sunmin Image Pictures.

The animators pencil each frame on paper using a light table, and then color them digitally on a layer beneath the transparent line work, to retain a hand-drawn quality.

[21] Animation Magazine later stated that the 30-person production team at Cartoon Network's studios that works on the series was "ruled by storyboards", which refers to the show being board-driven rather than script-driven.

For instance, the series featured two married couples: Lord Boxman and Professor Venomous, two villains, and Joff and Nick Army, two recurring heroes.

[25][26] Before the episode aired, Jones-Quartey confirmed Army and Joff as a canon gay couple[27] and Gregg, a minor character, as non-binary.

[44] When asked about Radicles' sexuality, Toby Jones, one of the supervising directors, confirmed that Rad is "pretty fluid and I think he understands that about himself".

[54] On August 6, 2019, Ian Jones-Quartey announced that Cartoon Network opted to not renew the show for a fourth season.

Lakewood Plaza Turbo, was launched on Android[60] and iOS[61] on February 4, 2016 as a free game for those platforms.

The game's original score was composed by Mathieu Lavoie and FX Dupas at Vibe Avenue in Montreal, Canada.

Melissa Camacho of Common Sense Media described the series as fun, with a "hard-working wannabe hero" but warned of cartoon violence.

She also called the series "quirky", said it has "lots of positive messages" and "clever moments", with some scenes understood more by young tweens rather than small children.

And he argues that "if the show doesn’t delve into that kind of world building, it still has the potential to be a zany comedy with a ton of heart that’s a cut above the rest."

And at the end he said that "Many other series on Cartoon Network, Steven Universe and We Bare Bears especially, took more than a season to really find their footing and I whole heartedly believe OK K.O.!
