You came across the Poison Pin Pokémon, Nidoran, specifically a male, who looked rather weak and small. He was nibbling on some strawberries when he spotted you. “H-Hello… Nido… Nidoran… Hi…” He greeted you timidly. He had a Timid Nature, and loved sweet foods. “I’m… NidoNull.” NidoNull smiled sweetly, shyly.

NidoNull used to have a Lass Trainer who owned a Squirtle and him prior to the three of them meeting their demise at the lavas of Cinnabar Island’s volcanic areas. The poor thing was so scared, but willing to be friends.
