When Lord Boxman takes away all the levels of the heroes' pow cards, K.O. must set things right and learn at heart that he is a true hero.

K.O. is controlled when fighting against villains. The player can use moves such as an uppercut, punch combo, low kick, etc. The player can collect their stats after defeating all enemies to earn new moves such as a charge punch, a controllable fist, and a stronger uppercut. During combat, taking damage or dealing damage will raise a bar towards using a special ability called a Powie Zowie, which summons a specific character. Examples include Rad, who allows players to levitate and shoot beams, and Carol, who will appear and attack with her combos.

Ian Jones-Quartey, the creator of OK K.O., was cautious about tie-in videogames that were of poor quality, and wanted to collaborate with a game development studio that shared his passion for the material and to create a video game in tandem with the show. This approach would ensure that neither the game developers nor animators would try to imitate each other. Cartoon Network connected him and OK K.O. co-executive producer Toby Jones with Capy Games. Jones-Quartey was already familiar with Capy and was thrilled to work with them. At the start of the collaboration, they were still brainstorming and developing the show, and wanted the game to develop in the same way. On December 7, 2017, the first trailer for the game was released.
