Name: Tigerstar
Calling: ThunderClan/ShadowClan/Place of No Stars
Pelt: Dark Tabby with unusually long front claws
Eyes: Amber
History: The Original Series
In the prologue, he took part in the battle with RiverClan, at Sunningrocks. Redtail, the deputy at the time, did not return, and Tigerclaw was the one who brought his body back and claimed Oakheart, the RiverClan deputy, had killed Redtail, and that he had killed him for revenge. Tigerclaw criticizes the new kittypet apprentice Firepaw, and takes a strong disliking to him when Firepaw realizes that he killed Redtail. He becomes deputy, when Lionheart was slain in a battle with ShadowClan, while he, Bluestar, Ravenpaw, Firepaw, and Graypaw were at Highstones.
He set up a trap for his leader, Bluestar, at the Thunderpath, near the burned ash tree. Bluestar had been ill with greencough, and could not come. Cinderpaw, disobeying Fireheart, went there and got caught in his trap instead.
Tigerclaw tries to murder Bluestar, meeting up with a group of rogues more than once beforehand, and getting them to the ThunderClan camp to distract the warriors left behind in camp, to fight the ones that weren't sent out on patrol. He was interrupted by Fireheart, but had he had gotten away with it, he would have intended to make it look like a rogue killed Bluestar. Bluestar exiled him from ThunderClan, as well as stripping him of his deputyship. He offered three cats to follow him, but Dustpelt, Darkstripe, and Longtail all refused.
As no more than an outcast, Tigerclaw gathers some rogues and attacks a patrol of Mousefur, Runningwind, and Thornpaw. He managed to kill Runningwind, while Mousefur and her apprentice made it back to camp. Tigerclaw is then once more seen, when Fireheart realizes that Whitethroat, a ShadowClan warrior he suspected of killing Runningwind, is looking over his shoulder at him. Fireheart then attacks Tigerclaw, but he looses the fight to Fireheart and Graystripe. As he retreats, he leaves this message for ThunderClan: that he would kill them all one by one.
Tigerclaw has taken over ShadowClan as their leader, and the other Clans do not see him as a traitor and a liar, but as a gift from StarClan to make ShadowClan strong again after their long time in sickness and tyranny with Brokenstar. A omen in the prologue mentioned to ShadowClan's medicine cat says that ShadowClan will survive and have a glorious future, but will pay the highest possible price for it.
Later, Tigerstar then begins hunting rabbits and leaving a trail for a pack of dogs he found living at Snakerocks, leading them back to the camp. He intended for ThunderClan to be wiped out, as full revenge. At the end of the trail, he lays Brindleface, a queen he murdered to give the dog pack a taste of cat blood. Longtail spots him though,, when he begins laying the trail.
When Fireheart plans to stop his plan, he stops him at the gorge so the pack leader can catch up. His plan soon fails, for Bluestar saves her deputy from death. He hears her secret, that Mistyfoot and Stonefur were her kits, and that she gave them up to become deputy instead of Thistleclaw.
Tigerstar brings a new Clan, made up of rogues living around a Twolegplace (which he and Boulder went to in the prologue) into the forest, making a deal that Scourge, their leader, and he, would rule the forest together. He tries to provoke fear into WindClan and ThunderClan using BloodClan, so that TigerClan (RiverClan and ShadowClan together) would rule the forest and drive BloodClan away. When told about Tigerstar's past, Scourge becomes enraged, and inflicts a wound from his throat down through his stomach, to his tail. Tigerstar dies, loosing all his nine lives one by one.
The New Prophecy
Tigerstar appears once more, to his ThunderClan son, Brambleclaw, in a dream. He says that he walks in a sky that StarClan does not know of, nor does he walk with StarClan. He promises Brambleclaw that he will see him and Hawkfrost again.
Tigerstar begins appearing regularly in Brambleclaw's dreams, in which he teaches them battle moves and how to be leaders. Hawkfrost agrees to follow his father's pawsteps closely, but Brambleclaw's expression was unreadable.
Tigerstar keeps training his sons, including more battle training and even wounding Brambleclaw in a dream that came true. He builds a plan with Hawkfrost, to test Brambleclaw and see if he was truly loyal to power. He planned for Hawkfrost to trap Firestar in a foxtrap, and see if Brambleclaw would tighten the noose around Firestar's neck, so that way he would loose all six lives and become leader faster. Tigerstar becomes enraged when Brambleclaw decides to release Firestar, but it is unknown how he feels about his son taking a cat with Firestar's blood as a mate.
Power of Three
Tigerstar, along with Hawkfrost, try to get Jaypaw, a blind apprentice who can see in dreams and read cat's minds, to go deeper into the Place of No Stars, promising to teach him warrior battle techniques. They try to lure him into their plans of revenge and power, but Jaypaw refuses when Spottedleaf appears with the permission of StarClan and guides Jaypaw away.
Tigerstar appears to Lionpaw, when he exits one day from the tunnels where he had been meeting Heatherpaw, a pretty WindClan apprentice. He starts to teach Lionpaw battle moves, first helping him on the badger defense, then teaching him more complicated moves. He then tells Lionpaw that his choice to become a great warrior is the only thing that he needs, and that he will be so powerful one day that he will not need any friends.
