Yes, he did, but only for defensive purposes. He killed Scourge, the evil leader of BloodClan. I don't think he killed any other cat.
Great question! You can find some on google. But if you are looking for Firestar, make sure that you type in "Firestar cat" or else you will get the superhero. Another place you can go is the website called warriorswish. There is lots of good fanart there. Goodluck! Also try going to Google and typing in warrior cats, firestar cat, graystripe cat, sandstorm cat, etc. Usually you'll click on a picture that leads to a website or blog that has TONS of pictures.
Clovertail is a light brown she-cat with green eyes, a white belly and legs. From "Firestar's Quest" & "Skyclan's Destiny"Warrior Cats
The first cat that Firestar gave his warrior name to was Thornclaw.
From Thunderclan: Spottedleaf&Bluestar Riverclan: Silverstream Shadowclan: Yellowfang Windclan: Onewhisker
It depends. If you mean someone to have their warrior name changed, then it's Brightheart. But the first apprentice to be made a warrior by firestar is actually Thornclaw.
The 're are two games on the oficiall site,(Extras->Games),and others like Warrior Cats Untold Tales (must be downloaded),Warrior Cats Firestar's Legend(wii game),games on Harper Collins Site,and others made by fans;
Sandstorm, because she mated with firestar
The cat on the cover of The Forgotten Warrior book is most likely Firestar. The Erins say that the cat on the cover will die, and all those rumors of Firestar dying in Omen of the Stars supports my theory. But, no one can be sure. And there is a possible chance that the cat on the cover might NOT be the actual, "Forgotten Warrior."
Warrior cat games are games that you can play online on the Warrior Cats websites.
NO not yet
Yes, he was the old leader of WindClan and a good friend of Firestar.
I'm almost positive its Firestar. i think that its Mistystar. She was born when Bluestar was still Bluefur and Firestar wasnt born yet.
