Lionheart
The first cat that Firestar gave his warrior name to was Thornclaw.
Brindleface gave Firestar the gift/life of protection. For kits, the need to defend your Clanmates, the vicious protection a cat gives for their loved ones. It was unbearable to stand for Firestar.
Yes, Firestar is a cat in the popular book series "Warriors".
Yes, Skywatcher was the the cat who told Firestar of the prophecy. "There will be three, kin of your kin, who will hold the power of the stars in their paws." Skywatcher came to Firestar in a dream, and also told him in person in Firestar's Quest.
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.
I don't know if your talking about going from a house cat to a warrior then do you mean Firestar?
The cat is most likely Firestar since he is one of the main characeters and the cat has orange pelt just Firestar's.
No, the character's name is Firestar, a significant character in the "Warriors" series by Erin Hunter. Firestar was originally named Firepaw when he first joined ThunderClan as an apprentice.
The three kin are Jayfeather (Firestar's grandson) , Lionblaze (Firestar's grandson) and Dovepaw (Firestar's brother Cloudtail's daughter Whitewing's kit). Hollyleaf (Firestar's granddaughter) was believed to be part of three, but it was revealed that she never had any powers and never will- meaning she was never part of 'The Three' in the first place.
No but he is not the wisest one either. he may not be wise, but he tries. long live firestar :)
no but he will die sooner or later no cat lives forever not even the grate Firestar
No cat name is good or bad, so that answer is yes and no
