firestar was created by Erin Hunter. The time he was created was 1981.
Firestar is now leader because he was deputy. it was questioned after her death by the clan but in the end, he became leader.
When Firestar became leader of ThunderClan he renamed Lostface (Brightpaw) Brightheart
i think it was at the ending of a dangerous path
Yes, he was the old leader of WindClan and a good friend of Firestar.
When he came to ThunderClan in Into The Wild he became Firepaw. In the end of Into The Wild, he became a warrior and became Fireheart, along with Graypaw becoming Graystripe, and in The Darkest Hour, he became ThunderClan leader and Firestar.
Firestar didn't die yet, but I'm gussing Brambleclaw
At the beginning of the Series, Firestar will be leader. If Firestar does join Starclan in this series, it does seem likely that Brambleclaw will succeed him as leader. Some other possibilities include:LionblazeGraystripe
No, he'll die in the same battle as Firestar.
Firestar
No, it is rumored that when firestar dies brambleclaw will be blinded and then there will be a new leader. It is not said who the new leader will be but i'm pretty sure it isn't graystripe. I belive that it will be Lionblaze!! Brambleclaw became leader when Firestar died in the last book and Squirrelflight bacame deputy so if Brableclaw gets himself killed before he goes to the moonpool Squirrelflight will become leader (unless she dies too)
theres loads on facebook or type firestar leader of thunderclan into google imiges
Everyone has a different opinion, but I think the "ultimate" leader is Firestar.
