Well if this was your question YES tigerstar dies. And not because Firestar became the hero and destroyed him but because Scourge leader of bloodclan rips all his lives from him. and the question you punched in is that he goes to the dark forest. He was exiled away from Starclan to spend the rest of his life in a shadowy forest of death. And later on they team up to destroy Starclan.
It dies
Well. In The Darkest Hour (The first series, 6th book), Scourge had killed Tigerstar. Then Tigerstar continued to torture other cats. In The Last Hope (Last series, 6th book), Firestar and Tigerstar have a battle. Firestar then kills Tigerstar and he fades away forever. Firestar then dies after as well.
No, Tigerstar does not kill Firestar in Omen of the Stars. Firestar dies under different circumstances unrelated to Tigerstar. Tigerstar's actions continue to affect the Clans, but he does not play a direct role in Firestar's death during Omen of the Stars.
He might become deputy once Firestar dies
Yes, he does. Tigerstar orders Stonefur to kill Graystripe's kits and Stonefur refuses, then Tigerstar orders Darkstripe to kill him, but Darkstripe is defeated, so he gets the help of Blackfoot and they kill him. This happens in "The Darkest Hour", the last book of the first series.
It dies and you get bloody pissed off.
After Tigerstar's death, Rowanstar becomes the next ShadowClan leader.
Goes to the beneficiaries heir's or estate.
Scourge is the leader of BloodClan, a Clan of kittypets from the TwolegPlace. Tigerstar dies when Scourge rips him from his throat to his tail-tip in a devastating blow, destroying him fatally so that not even his nine lives can save him. He eventually dies nine times over.
everything dies! Not everything dies, only the leaves the tree will survive unless you cut it down
once, in Warriors: The New Prophecy #6: Sunset
If your mate dies on wolf quest, you will have to save your game then quit, then go on the same file again. It happens rarely tho... I have only had my mate die once and i did that^^ and it worked out fine. Hope this helps
