Yamato Tribe Prince Geki

"TyrannoRanger! Geki!"

Yamato Tribe Prince Geki (ヤマト族プリンス ゲキ, Yamato Zoku Purinsu Geki) is TyrannoRanger, the leader of the Zyurangers, and Burai's little brother. He is the known as the "Warrior of Justice". He was 24 years old when Zyuranger began (43 as of Gokaiger).

Zyuranger
It is revealed that Geki was really adopted by the Yamato King. After the death of his older brother, Burai, the Dragon Armor and Zyusouken were given to him. When he wears the Dragon Armor, he is called Armed TyrannoRanger, and can generate his power three to five times higher than usual. He is a passionate leader with a strong sense of justice, even though there had been very humorous moments.

Geki was raised well and deeply loved, but kept ignorant of several facts pertaining to himself. Those facts nearly got him killed when the truth came out.

Faced with the truth and his brother Burai so far into the future, Geki could do nothing else but want to have his brother, and give him peace and the familial love the man had lost, so long ago. And eventually he did win through to Burai's heart, but scant comfort was to be had, for his brother was dying, rapidly.

Losing him was probably worse than leaving his dying people and for a time, Geki nearly broke under strain. But Goushi reminded him that the most important thing of all was to save the future. "If you lose sight of that in your despair, you become an agent of evil if indirectly."

Super Sentai World
Geki later led his team in joining forces with the Fivemen, Jetmen, Dairangers, and Kakurangers to defeat the evil Emperor Daidas and his forces.

Gaoranger vs. Super Sentai
TyrannoRanger is among the Sentai warriors seen in clips when Yuusuke Amamiya (Red Falcon) lectured Gaku Washio (GaoYellow) about the past Sentai sword experts, showing him that the true sword wasn't the sharpest, but the one that feeds on courage.

Led by his Liveman predecessor Red Falcon, he appeared as one of 24 previous Red Rangers in Gaoranger vs. Super Sentai together with fellow Red Rangers from his predecessors AkaRanger to Red Hawk to his successors from RyuuRanger to TimeRed.

Gokaiger
Years later, Geki fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. He was seen along the Bakuryuu Sentai Abaranger team and was using the Armed Tyrannoranger mode to fight off the Zangyack. After fighting against hundreds of Gormin and their Zgormin commanders. Kaijou noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. The TyrannoRanger powers are later used by Captain Marvelous via the Ranger Keys.

After the Zangyack's final defeat, Captain Marvelous returned the Ranger Keys to their original owners. Since Goushi got his powers back as he saw the Gokaigers off, Geki, Goushi and their teammates have their powers back.

Super Hero Taisen
Geki, alongside his team (bar DragonRanger), was among the majority of the Super Sentai heroes caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker.

Akibaranger
Both Geki and Burai make an appearance in Episode 5 of Hikonin Sentai Akibaranger Season 2 with the neck collars and belts of their suits changed from white to the stars and stripes of the American flag. Both he and his brother acted like stereotypical American alpha male bullies who proceeded to beat up The Akibarangers and called them knockoffs of Powerful Rangers. (An inside-joke reference to the real world Super Sentai vs. Power Rangers arguments found on the Internet) However, Akiba Red's insistence that the truth of always fighting evil and supporting children despite the bullying broke the spell, returning both Geki and Burai to their normal selves and eventually lent their Inordinate Powers to the Akibarangers.

The six Zyurangers later appeared with the now five official Sentai, transforming into their Ludicrous Power which combined with the others to form the Ludicrous Cannon Bazooka, which the Akibarangers used to destroy Kameari Alpaca.

Ranger Key
The TyrannoRanger Ranger Key (ティラノレンジャーレンジャーキー) is Geki's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The TyrannoRanger Ranger Key was mainly used by Captain Marvelous (Gokai Red), who used it to fight as TyrannoRanger.
 * When the Gokaigers became the Zyurangers while fighting Deratsueigar of the Zangyack Imperial Guard.
 * When the Gokaigers became the Zyurangers while fighting against Jealousto and his Gormin Sailors.
 * Gai uses this key alongside all other Red keys after being merged with Captain Marvelous by Insarn.
 * In a deleted scene, the Gokaigers became the Zyurangers to demonstrate their powers to Ninjaman.
 * After being given the Dragon Armor by Gai (DragonRanger), he became Armed TyrannoRanger and took down a pair of Dogormin.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Geki received his key and became TyrannoRanger once more.

Red Spirit
As the sixteenth Red, TyrannoRanger's Red Warrior Spirit was embodied by AkaRed.

Imitations
Dora Mirage took the form of TyrannoRanger as part of the Fake Zyuranger.
