Nomèkop

Nomèkop is a video game series, trading card game, and TV show from RO-Japan. Nomèkop started out as a video game, Nomèkop Red, then evolved into a trading card game and TV show. Nomèkop seems to be a favorite of Jo, both a video game favorite and a TV favorite. When Nomèkop is first mentioned by Jo to Ratchet and Sadie, they have no idea "what the hell he's talking about", but Jo teaches them when they agree to take his so-called class after they defeat Fät Corp.

The Nomèkop TV show, split apart into 5 different portions, is revealed to be Jo's favorite TV show at the end of book 5. Jo tells his parents that the five portions of Nomèkop are Otnak, Othoj, Nneoh, Honnis, Avonu, Solak, Alola and Ralag, respectively. It is also revealed that each portion has a different theme song.
