It is likely that Brambleclaw will become leader after Firestar since Brambleclaw is currently the deputy. However, anything is possible.
Some possibilities for the new leader include:
There are many other possibilities as well.
Answer to above answer:
It has already been confirmed that Brambleclaw nor Greystripe will become leader after Firestar.
Another thing that I have noticed is that Erin Hunter never uses the same leader name twice. Example: The leader of Skyclan when they were forced to leave the forest was named Cloudstar, so Cloudtail well not become leader after firestar dies.
Lionblaze becoming clan leader is a posibility, and so is Cinderheart.
Also I know people keep asking is 'how many lives does firestar have left?'
He has 2 lives left at the end of fading echos, the second book of omen of the stars.
It has also been confirmed that Firestar is going to die at the end of the fourth series.
no, after firestar dies, brambleclaw becomes leader and squirrelflight becomes the deputy
After Bluestar dies, she is succeeded by Firestar (Fireheart) as leader.
After Bluestar dies, in Thunderclan, the next leader becomes Firestar. After Crookedstar dies, in Riverclan, the next leader becomes Leopardstar, then Mistystar. After Tallstar dies, in Windclan, the next leader becomes Onestar. After Brokenstar is exiled, in Shadowclan, the next leader becomes Nightstar, then Tigerstar, then Blackstar.
Firestar dies and a mew cat machetestar becomes leader
Fireheart becomes leader after Bluestar!!!!! He becomes Firestar. You were either on a book between 1-3 or didn't read the books. No one reads the books. I can't be a fan without reading, because then I won't know what happens.
If he becomes deputy of Brambleclaw once Firestar dies and once Bramblestar dies. Sorry but Hawkfrost read the question carefully. Lionblaze would only succeed Firestar if something happened to Brambleclaw before becoming leader. Then if he was chosen to be leader he would be Firestar's succesor.Hawkfrost's answer said Bramblclaw would be Firestars succesor.
After Tigerstar's death, Rowanstar becomes the next ShadowClan leader.
Firestar dies and brambleclaw does not come the next leader
No, he'll die in the same battle as Firestar.
after she dies, fireheart becomes firestar, and graystripe is made deputy.
He becomes Thunderclan leader.
Actually, he does become leader in the last book because Firestar dies.
