On March 9, 2017, nearly four years after the original short's premiere, Cartoon Network announced that the television series had been greenlit.[5] 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 May 5, 2018.[6] A third season, which was announced in June 2019,[7][8] premiered on July 7, 2019. It was also confirmed that the series was cancelled and will conclude after the airing of its third season, and that the series finale will be airing later in the year.[7][9]



OK K.O.! Let's Be Heroes is set in the retro-futuristic year of 201X. 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. 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.

Voice CastEdit


To promote OK K.O.! Let's Be Heroes, Cartoon Network's Chief Content Officer Rob Sorcher hinted many times in an interview that it would become a full series.[17] Its multiple storyboard artists have also been seen on Twitter.[18][19][20][21][22] On March 9, on PlayStation's Blog, Chris Waldron VP of Games & Digital Products for Cartoon Network announced a series in the works, along with a video game.[23] The series was premiered by Cartoon Network on August 1, 2017. The first 6 episodes were released online on June 13, 2017.

The show is animated traditionally in South Korea by Digital eMation and Sunmin Image Pictures.[24] Unlike many animated programs, which are inked on paper and then scanned for coloring, OK K.O.! is 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 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.[25]


OK K.O.! Let's Be Heroes had its worldwide television premiere in the US on Cartoon Network on August 1, 2017, and aired on sister network Boomerang from August 7 to September 1, 2017.[26] In Canada, it premiered on August 1 on Cartoon Network and on September 4 on Teletoon.[27][28] In Africa, the shorts were released on September 11 and the full series premiered on November 18, 2017.[29][30] It premiered in the UK and Ireland on October 9, 2017.[31] It premiered in Australia and New Zealand and the Philippines on January 6, 2018 and in Southeast Asia on January 20, 2018,[32][33] Cartoon Network Korea on December 1, 2017, and Cartoon Network Japan in July 2018.
