During the 9th day of Twitch Plays Pokémon Red Version, on one of RED's Safari Zone catching sprees, he managed to catch several Pokémon species, one of which being a Nidorino. At the time, the Hive Mind only thought of the Nidorino as another irrelevant catch.
The events of Bloody Sunday occurred a 3 days later, 12 Pokémon were released, Nidorino was one of the many Pokémon that survived the event. Because some of the semi-decent Pokémon were released, Nidorino was forced into the role of being one of RED's party Pokémon. Over time, Nidorino grew increasingly stronger, eventually evolving into a Nidoking after receiving a Moon Stone.
