I've been looking for Tigerstar is good stories, but they are few and far between, and I've also been looking for Evil Firestar and those too are few and far between, so here is my take, on what if the roles were switched.

Switched:

Prologue

Tigerclaw jumped at the RiverClan cat snarling and clawing at its pale blue pelt, when a large dark red tom torn him off the cat, "No ThunderClan cat will ever harm a hair on his pelt." The RiverClan deputy snarled (Just a note, I don't own Into the Wild, I have only read it once, and that was a long time ago, I am going off the Warriors Wiki and what I can remember and other fanfictions)

Oakheart jumped at Tigerclaw his claw unsheathed, a tortoiseshell tom jumped forward and tumbled with Oakheart, rolling under a rockfall, Tigerclaw heard a rumbling and looked up and the rocks began to fall, "Redtail!" He called, "Look out!" But it was too late the ThunderClan deputy was crushed along with Oakheart.

Tigerclaw looked around, ThunderClan was losing, "ThunderClan retreat!" He called to the cats, and the cats dove into the brush around the area.

Thistlestar sat looking at the stars on the Highledge, letting the moonlight flood over his fur, his ears were turned to the forest, as if trying to hear the patrol he'd sent to Sunningrocks, another cat slipped up behind him.

"How is Mousefur?" He asked his voice low and raspy

"She will heal." The tortoiseshell she-cat said, "Her wound was deep, but she is young."

"At least that is certain." He rumbled "Has StarClan spoken to you recently?" The gray and white tom asked

"Not for some moons." Spottedleaf replied looking up at the same stars as Thistlestar, "But I am confident that they are with us."

"Then they are." Thistlestar said looking down

As he spoke a bright light whizzed across the sky, the light catching Thistlestar's eye he turned to look at Spottedleaf, but her eyes were round and focused, questions burned in his mind, but kept quiet.

"It was StarClan." She breathed at last, "They have told me that Fire can save our Clan, if led the right way."

"But Fire destroys not saves." Thistlestar exclaimed,

"StarClan has spoken." Spottedleaf said, "That is all I can say, but if you wish to challenge our ancestors."

Thistlestar shook his head, "I may not understand it, but StarClan has spoken, Fire will save our Clan."
