OK K.O.! Let's Be Heroes

'OK K.O.! Let's Be Heroes' is an American animated television series created by Ian Jones-Quartey for Cartoon Network. 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. It was produced by Cartoon Network Studios. The web series premiered on Cartoon Network's YouTube channel and on Cartoon Network Video on February 4, 2016.

On March 9, 2017, nearly four years after the original short's premiere, Cartoon Network announced that the television series had been greenlit, and it premiered on August 1, 2017. The opening sequence was storyboarded by Japanese artist Hiroyuki Imaishi, co-founder of Studio Trigger.

On December 4, 2017, the series was confirmed to be renewed for a second season, which premiered on March 18, 2018. A third and final season, which was announced on June 26, 2019, premiered on July 7, 2019; the final episode aired on September 6, 2019.

As of August 2022, the show has been available on Hulu. It was also made available on HBO Max after its launch, but was one of several shows removed in August 2022 as a result of the Warner Bros. Discovery merger.

The series follows the titular character, K.O., and his efforts to become the world's greatest hero while working at Gar's Bodega (run by Mr. Gar), a hero supply shop in Lakewood Plaza Turbo.

Production
The pilot, "Lakewood Plaza Turbo", aired in 2013, and the show was announced in March 2017, with the first episode airing on August 1. To promote ''OK K.O.! Let's Be Heroes'', Cartoon Network's Chief Content Officer Rob Sorcher hinted many times that it would become a full series. On March 9, 2017 on PlayStation's Blog, Chris Waldron, the VP of Games & Digital Products for Cartoon Network, announced a series in the works, along with a video game. It was announced as part of a slate of animations for the 2017-18 season, alongside new series such as Craig of the Creek and Summer Camp Island, and recurring series.

The show was traditionally animated in South Korea by Digital eMation and Sunmin Image Pictures. Unlike many animated programs, which are inked on paper and then scanned for coloring, OK K.O.! was drawn in pencil. 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. For Jones-Quartey, it was important for the audience to "never forget that these are drawings". This was partially inspired by the first season of The Simpsons, which had a loose, rough quality to its animation. In addition, the show's design sense is inspired by Yoshi's Island. 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. Diego Molano, later a creator of Victor and Valentino, was a character designer on the series.

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. He also stated that each episode takes nine months to work on "from start to finish", and stated that the series spoke to kids who are interested in superheroes, "special powers" and enjoy drawing.

In August 2021, Ian Jones-Quartey told Insider that in hiring people for the show, he avoided relying on a trusted network of people, prioritizing finding a diverse group of people, doing many open calls, with the studio having a database with which they "sort of cold emailed people", then asking people to come in after looking at what they had done in the past.

LGBTQ representation
Series creator Ian Jones-Quartey hinted at this in an interview with Den of Geek published a day before the first episode aired, saying those watching it would "be delighted" by the LGBTQ representation in the series. There were LGBTQ characters in the main cast, among supporting characters and other recurring characters. For instance, the series featured two married couples: Lord Boxman and Professor Venomous, two villains, and Joff and Nick Army, two recurring heroes. The series was noted as portraying Boxman and Venomous romantically, and ending with a same-sex wedding between Joff and Army in the series finale "Thank You for Watching the Show" on September 6, 2019. Before the episode aired, Jones-Quartey confirmed Army and Joff as a canon gay couple and Gregg, a minor character, as non-binary. Enid, a bisexual ninja and witch, and Red Action, a lesbian, were recognized by GLAAD as a couple, and kissed in the episode "Red Action 3: Grudgement Day".

The series was later recognized by Philadelphia Gay News and Out for its LGBTQ representation.

The show creators also stated that Yellow was possibly Red's ex-girlfriend, with the show's crew calling Enid and Red a "committed couple," and saying their relationship developed "very naturally." Jones-Quartey later said that Red Action and Enid "run a dojo together and kiss." Other reviewers stated that Enid has possible romantic feelings toward Elodie. Additionally, Gregg, a minor character, was confirmed as non-binary by Jones-Quartey, who also confirmed Venomous as bisexual, but not non-binary, and Boxman as pansexual. In October 2020, Jones-Quartey added that Professor Venomous and Lord Boxman of ''OK K.O.! Let's Be Heroes'' were married at the end of the series. Jones-Quartey also said that The Hue Troop, which Red was once part of, are all LGBTQ characters. 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".

Video game
A mobile game, ''OK K.O.! Lakewood Plaza Turbo'', was launched on Android and iOS on February 4, 2016 as a free game for those platforms. It is a beat 'em up developed by Double Stallion Games and published by Cartoon Network Games.

Capybara Games developed a video game based on the show for the PlayStation 4, Xbox One, and Windows. Entitled OK K.O.! Let's Play Heroes, it was released on January 23, 2018, and a Nintendo Switch port was released on October 30, 2018.

Reception
The series was received positively. 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.

Praise has been given to the series' overarching storyline and character writing, as well as for its LGBTQ representation.
