Warriors: Into The Wild

Shadowpaw is a black and white ThunderClan apprentice with a blind eye and blue eye. He used to be a kittypet named Two-Tone but his twolegs shot his left eye, earning him the blind eye and causing other kittypets to bully him. Bluestar found him scared, injured, and bleeding, and Spottedleaf took him on as her apprentice, earning the name Shadowpaw. This accident caused him to be very distrustful towards kittypets and twolegs.

Until, one day, when he, Bluestar, Lionheart, and Graypaw were on patrol, Graypaw dragged him away from the patrol and into trouble, where they met the only friendly Kittypet alive (in Shadowpaw's eyes anyways, Graypaw believed there were other nicer kittypets), named Rusty, also known as Firepaw. From this day forward, Shadowpaw's life changed forever.
