Fenix was a protosszealot, and praetor of the Protoss Defense Forces. He personally led his fellow warriors into battle against those who called themselves the enemies of the Protoss Empire. Revered by his warrior-brethren, he was dubbed the Steward of the Templar, and is one of the most celebrated heroes in protoss history.
"It was the proudest moment of his life. He felt such purpose, such surety of his existence..."
Fenix was once part of a legion that was ordered to rescue the last surviving brother of four zealots. During the operation, the entire legion was killed except for Fenix and the target.
When a disgraced executor and his legion seized The Rock, Fenix was sent in to secure the facility. He subdued the terrorists before the facility was purified.
When Fenix's legion was slain by mercenaries, he was captured, and the mercenaries attempted to use Fenix to assassinate JudicatorAldaris. After breaking free, Fenix hunted them down one by one.
During a hostage exchange on a border world, Fenix and his legion were met with an unknown alien species that divided his forces and hunted them down like prey. Fenix defeated the alien in martial combat, and survived its explosive suicide.
Fenix was invited by PraetorAdomis to come to the ceremony for the decommissioning of the super carrierAntimond. However, the super carrier was seized by protoss rebels, and Fenix fought to prevent them from seizing the ship.
In the aftermath of the Kalath Intercession, Fenix and his templar brethren were met with hostility on their return to Aiur. These tensions culminated in an incident where templar warriors were ordered to fire on Fenix.
Fenix was deployed to the world of Dannuth VII, inhabited by a race called the tagal. Fenix and Artanis led their forces against them and although the protoss were outnumbered 30:1, they still emerged victorious.
The Great War
During the Great War, Fenix was deployed to Antiga during the zerg invasion of the world. A scout pilot crashed behind zerg lines, and Fenix gathered twenty warriors to save the pilot. The group slaughtered thousands of zerg in their rescue operation.
The Invasion of Aiur
"You know, Executor, although we two have marched across hundreds of worlds together, I never imagined that we would be fighting on Aiur. The Zerg are indeed worthy foes."
When the zerginvadedAiur, Fenix stood in defense of the province of Antioch, guarding a strategic outpost. However, his forces were nearly overwhelmed by the zerg. JudicatorAldaris sent Fenix's old comrade, the new executor, to rescue him, and together they defeated the zerg incursion.
When Tassadar contacted Aldaris with information about zerg cerebrates, a weak spot in their hierarchy, Fenix agreed to test the new strategy for Tassadar over Aldaris' objection. The test, however, was a failure, as they had not received complete information from Tassadar.
Aldaris ordered a strike against the zerg forces in the province of Scion, leaving Fenix behind with a small force to defend the outpost in Antioch.
Unfortunately, during the Second Battle of Antioch, Fenix was defeated by the zerg. Fenix was nearly ambushed by a hydralisk; as he sought to slay his foe, his psionic blades ceased to function. Fenix's ruined body was recovered and placed into a dragoon exo-skeleton.
Return to Aiur
"Greetings Executor! And greetings to you, Tassadar. I am overjoyed to see you both return home in this dark hour. The Zerg have redoubled their efforts, and it seems-" "Fenix? It can't be! The Executor told me of how you fell before the Zerg. How is it that you live and breathe?" "Ha hah... Well, after my unfortunate defeat, my ruined body was recovered by our brethren. I now reside within the cold, robotic shell of a Dragoon."
- Fenix greets Tassadar upon the latter's return(src)
When Tassadar returned to Aiur, Fenix gladly joined his rebellion against the Conclave. Tassadar was surprised to see Fenix alive, and in the shell of a dragoon. Fenix, along with DarkPrelateZeratul and his dark templar, assisted in the destruction of Kor-shakal, but Tassadar, unwilling to let his brethren continue killing each other, surrendered and was spirited away by Aldaris.
The Dark Templar vanished, and Fenix wondered if it had been wise for Tassadar to have put any faith into them. Fenix refused to stand by while the Conclave prepared to execute Tassadar. Joined by Tassadar's terran companion, Jim Raynor, Fenix embarked on a desperate rescue attempt. The would-be rescuers were surrounded by the Conclave's troops as they reached Tassadar's stasis cell, and were in turn rescued by Zeratul and the Dark Templar.
Fenix proposed sending his forces to engage the primary zerg hive clusters to thin out their numbers, enabling Zeratul to slay a pair of cerebrates. He believed the Overmind would be distracted by the attack long enough for the protoss to assault it directly. Fenix personally joined in the attacks. The protoss, Fenix included, moved through the weakened zerg defenses around the Overmind. The attack was failing until Tassadar sacrificed himself to destroy the Overmind.
The Brood War
"Don't let the fact that I am three hundred and sixty eight years older than you dull your impression of me, young Raynor. I can still... how do you Terrans say it... "Throw down with the best of them!""
The death of the Overmind caused the zerg to rampage across Aiur. The Conclave was destroyed and seventy percent of the population was killed. Fenix joined Aldaris, Zeratul, and Raynor to unite and lead the scattered survivors. The refugees followed Zeratul's plan of traveling to Shakuras through the sole functioning warp gate on Aiur. At the gate, a large force of zerg attacked them; however, Fenix and Raynor arrived and fought the zerg long enough for the refugees to escape. Fenix and Raynor didn't make it through the gate, however. Instead, they fought to secure their end of the gate and close it so that more zerg could not reach Shakuras. Despite the overwhelming odds, Fenix and Raynor decided to fight to the end. While there, Fenix and Raynor were contacted by Sarah Kerrigan, who told them about the new Overmind and the United Earth Directorate's plans for controlling it. Protoss forces rescued Emperor Arcturus Mengsk from the UED, which had just defeated him, and spirited him away to Aiur.
The UED pursued, and Fenix's refugee base was destroyed by the Earth-borne humans and by zerg attacks, but not before Raynor and Mengsk escaped through the gate. The warp gate self-destructed immediately afterwards.
Fenix and Raynor fled to Shakuras. During his time there, a nuclear device detonated in the heart of New Antioch. Fenix and a Khalai Caste worker wandered the railway under the city to hunt down the Nerazim terrorists responsible for the attack, and found it to be lead by the brother of the Nerazim Fenix had slew three years earlier. Fenix slew him and ended the terrorist threat.
Kerrigan later contacted Fenix and Raynor  asking for their help. Fenix and Raynor joined an unusual alliance with Kerrigan and Mengsk on Tarsonis in order to oppose the UED, which now had control of the Overmind and numerous zerg minions, and were bolstered by their anti-zerg weapon, the psi disrupter. Fenix never trusted Kerrigan, but he followed Raynor's lead.
Following the destruction of the psi disrupter by Kerrigan's forces (with assistance from Raynor and Mengsk), enabling Kerrigan to partially rebuild her forces, the allies plotted to free Korhal from the Directorate forces. In order to do so, Kerrigan needed ten thousand units of minerals to build up her primary hive clusters, and the best place to acquire that kind of wealth was Moria, one of the largest resource nodes in the sector. Of course, its ruling power, the Kel-Morian Combine, would object to this kind of invasion. Fenix said that if it would better their chances, he would personally lead the invasion.
Fenix personally led the zerg forces in acquiring the minerals from Moria. During the battle, Fenix disdained the fuel raid he was on, wishing he could fight the huge epic battles of his youth. Raynor jokingly accused him of sounding like a tired, old man, but Fenix replied he could still "throw down with the best of them."
During the battle, Fenix wondered why the Kel-Morian Combine did not oppose the UED, which had overthrown their former masters, the Terran Dominion.
The raid was successful, after which the allies traveled to Tarsonis.
"The Khala awaits me, Kerrigan. And although I am prepared to face my destiny, you'll not find me easy prey!"
On the UED-conquered world of Korhal (formerly the Dominion throne world), Fenix and Raynor struck at the UED's more outlying fortification, while Kerrigan's troops assaulted the main UED base at Augustgrad.
While they defeated the UED and their enslaved zerg, Kerrigan and Samir Duran engineered a betrayal. Fenix, who was not entirely surprised, prepared to face her forces on the battlefield. Fenix fell to the Swarm.
"What have you done?" "What I had to." "Tell that to Fenix! Tell it to the millions you butchered!"
Upon his death, Kerrigan mocked Raynor, saying that Fenix died the way all protoss hope to do: in combat. Enraged, Raynor swore he would kill Kerrigan for this betrayal. In the final battle of the Brood War, Praetor Artanis led a protoss attack against Kerrigan, partly aimed at avenging Fenix. The attack was unsuccessful, however.
Five years later, Fenix's death was still a sore spot for Raynor, one that he raised with Kerrigan when they reunited on the Moros.
By the End War, Fenix was regarded as a "legendary" figure among the Daelaam. Later on, during the conflict, a copy of Fenix's conscience was reactivated in the body of an experimental purifier and would become known as Talandar.
Fenix was a powerful warrior, and led directly from the frontlines. Fearless and honorable, he embodied the best aspects of the Khalai. Zeratul described Fenix as being "as stalwart a warrior as I have ever known" and Kerrigan acknowledged him as being "uncannily resourceful." He has proven himself to be one of the strongest protoss warriors of all time.
In battle, Fenix would repeat a code to himself, "I fear no enemy. For the Khala is my strength. I fear not death. For our strength is eternal." It would remind him why he fought.
"Fenix" is the Middle English spelling of "phoenix," a bird from Greek mythology that is cyclically reborn.
In the StarCraft: Brood War campaign and in the last four missions of Episode III, protoss structures use Fenix's dragoon portrait instead of Aldaris's portrait.
According to James Waugh, Blizzard is aware that Fenix is "an absolute fan favorite." He has also stated that Fenix is "an absolute James favorite" as well.

Though I fear you would doom us all, Aldaris, I surrender myself to the Conclave. En Taro Adun, Executor. Don't give up the fight!" Aldaris: "Tassadar of the Templar, by your actions you have severed yourself from the mercy of your brethren. You refused to destroy the Terran worlds as was commanded. You have questioned time and time again, the sacred will of the Conclave. And you have abandoned your Homeworld in its darkest hour. Most grievous of all is that you have allied yourself with the blasphemous Dark Ones, and learned to utilize their profane powers in tandem with our own! What say you, oh fallen Templar?" Tassadar: "Aldaris, I submit myself to the Conclave's judgment. But know this, given the same choices again, I would surely have made them. I have sacrificed all that our world might live. I have sullied my honor, I have discarded my rank and standing, and I have even broken our own most ancient traditions. But never think that I would, for one moment, regret my actions.

Your Conclave believes that they are winning this war, but all they've succeeded in doing is helping the Overmind to win." Aldaris: "What could you possibly know about our designs, blasphemer?" Zeratul: "You speak of knowledge, Judicator? You speak of experience? I have journeyed through the darkness between the most distant stars. I have beheld the births of negative-suns and borne witness to the entropy of entire realities... Unto my experience, Aldaris, all that you've built here on Aiur is but a fleeting dream.
