Firestar

Firestar is a cool-looking flame-colored tomcat with green eyes. He used to be a kittypet named Rusty before he joined ThunderClan and later became Firestar. He has a mate named Sandstorm and was a great leader. He died in a fire. The leader after him was Bramblestar/claw. More on his life:

He came into the Clan as Firepaw. Longtail thought he was still a kittypet. They fought, and Firepaw tore off his collar. After that, he was seen as a real apprentice, although the Clan had their doubts about him. Tigerclaw added him to most patrols going near Twolegplace. When he became a warrior, Fireheart, all seemed well for a while, until he found out that Graystripe, his best friend, was visiting a RiverClan she-cat. Graystripe was neglecting his apprentice, Brackenpaw, while Fireheart took over most of Brackenpaw's training because his apprentice, Cinderpaw, had got hit by a car when Tigerclaw set that trap for Bluestar. Fireheart saved Bluestar from being murdered by Tigerclaw in the fake rouge attack and became deputy. When BloodClan attacked, he was leader, Firestar. They fought, and won. BloodClan was drove out of the forest, and Firestar was the rightful leader of ThunderClan.
