Tigerstar and Bluestar

Even though I've outgrown Erin Hunter's Warriors series, I still do love the concept and the characters. The one on the right is Bluestar, the leader of ThunderClan, and the one on the left is Tigerstar, a tyrant leader who tried to combine RiverClan and ShadowClan to create TigerClan. (Please correct me if I'm wrong, it's been a while.)
Thank you for looking!
