Crookedstar

Crookedstar is a huge but elderly light-colored tabby tom with green eyes and a twisted jaw.

Old Information
Crookedstar is the respected leader of RiverClan, father of the well known Silverstream.

Into the Wild

 * When he is first introduced in Into the Wild, he is already elderly and fragile, but remains with a firm hold on reality. He organizes several attempts to steal back Sunningrocks but fails. In Into the Wild, Firepaw describes his twisted jaw to look as though it had been badly broken, and then healed incorrectly.

Fire and Ice

 * While it is still a mystery as to how he received his twisted jaw, it is hinted in Fire and Ice that it was a souvenir from a battle.

Forest of Secrets
He is mentioned from Bluestar to Graystripe when Silverstream died just so he won't acuse her of Silverstram's death at the next gathering. Graystripe was not allowed at gatherings.
