Hyuuga

"Black Knight! Hyuuga!"

- Hyuuga

Hyuuga (ヒュウガ, Hyūga) is 40 years old and the older brother of Ryouma' (GingaRed). He was chosen to be the 133rd GingaRed, but he fell into a pit created by Captain Zahab. He later becomes the Black Knight II (2代目黒騎士, Nidaime Kuro Kishi) after the spirit of BullBlack passes his powers onto him.

Gingaman
He is saved by Black Knight BullBlack, who possesses the young man's body for a time before releasing him. Soon thereafter, Hyuuga is given the power to become the new Black Knight. But later when Heavy Starbeast GoTaurus is wounded in battle against Evil Empress Illiess, it is captured by Barreled Scholar Pucrates who blackmails Hyuuga to come work for him so he could sever his connection to the Earth in order to wield the cursed Knight Axe, the only thing that can shatter Zahab's Star Soul Jewel. Hyuuga agrees to give up his Earth power in hopes of using the Knight Axe to kill Zahab. Hyuuga will roar with laughter even for any kind of petty gag.

Hyuuga regains his Earth Power in the finale after the Knight Axe's destruction, and fought as the Black Knight alongside the Gingaman to kill Zahab after he and Ryouma destroy Zahab's damaged Star Soul Jewel together with a dual fire attack.

Like Ryouma, Hyuuga controls the "earth" element of fire, though he does not use it in special attacks like the other Gingamen. He can become the Heavy Knight with the aid of GoTaurus.

Hyuuga also appeared in Kyukyu Sentai GoGo-V vs. Gingaman as a supporting character where he and Yuuta Aoyama teamed up with Mondo Tatsumi in locating the Gingamen's Star Beasts to awaken them from their slumber. Once he used his power for that purpose after locating the Starbeasts, Hyuuga briefly fought as Bull Taurus to help his teammates back up the GoGo-V against the Infernal Dark Hellbeast.

Gokaiger
Hyuuga fought in the Great Legend War, along with the first 34 Super Sentai teams, as a member of an "extra hero" squadron who assisted the Goseigers, Tsuyoshi Kaijou and Soukichi Banba reach the battleground where the final showdown occurred. He, along with everyone else, sacrificed their powers to destroy the Zangyack armada. Hyuuga's Ranger Key, along with those of the 9 other Extra Heroes, ended up in the hands of Basco ta Jolokia.

Sometime after the Great Legend War, he went back to his home in the Ginga Forest. One day, Basco arrived and attacked him, injuring him greatly. It was during this attack that the Gokaigers arrived to gain the Greater Power of the Gingaman where Gai recognizes him as the Black Knight. Soon after, Basco summons DekaMaster, MagiMother, and Wolzard Fire, leading the Gokaigers to battle with them and having Gai take Hyuuga somewhere safe. Gai manages to get Hyuuga away from the danger and tend to his wounds.

As Gai tells him of his dream to become a member of a Super Sentai, he asks Gai for his Gokai Celluar so he could defend the Earth as Gokai Silver. Before he gives it to him due to his doubts, they are attacked by Basco who proceeds to take the Greater Power away before Marvelous arrives and stops him. However, Basco uses the Black Knight Ranger Key and has him attack Marvelous which causes Gai to drop his Celluar and still doubts that he would be able to defend the Earth like Hyuuga did.

With a bit of unintended encouragement from Marvelous after being attacked by Basco's summoned Sentai Warriors, Gai tells Hyuuga that he must be Gokai Silver no matter what and that he'll defend the Earth for him and everyone. Hyuuga tells Gai that was exactly what he wanted him to say as he wanted Gai to believe in himself more. Gai proceeds to defeat the summoned Black Knight and in turn the key absorbs the Gingaman's Greater Power through Hyuuga.

After the battle, Hyuuga gives the Ranger Key to Gai saying that he would rather have all the Sentai Powers in one place and gives Gai his blessings to defend the Earth. He meets with his brother Ryouma and asks him if he still didn't trust pirates to which he answers he doesn't, but he trusts them as they would lay their lives on the line for each other. Hyuuga and Ryouma look off to the sky as the Gokaigers depart. The other nine Extra Hero keys would later be taken from Basco when the Gokaigers unlocked the greater power of Ohranger.

When the Gokaigers first transformed into Extra Heroes, in their fight against the Dogormin, Gai became the Black Knight. Later, during a trip which involved time-travel, Gai honored his promise to Hyuuga by using the greater power of Gingaman. When the Black Knight Key is inserted into GouJyuJin, it performed the GouJyu Eidan attack, a spinning bifurcation attack similar to Combined Beast-Warrior BullTaurus' signature finisher.

After the Gokaigers defeated the Zangyack, Marvelous returned the Ranger Keys to their original owners. Hyuuga and his team have their powers back.

Ranger Key
The Black Knight Ranger Key (黒騎士ヒュウガレンジャーキー) is Black Knight'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 other nine extra hero keys and the fifteen sixth ranger keys, were initally acquired by Basco ta Jolokia and later used by the Gokaigers. Like all of his Ranger Keys, Basco used his trumpet, the Rapparatta, to turn the Black Knight key into a puppet to do his bidding. After revealing his extra Ranger Keys to the Gokaigers in the Ginga Forest, Basco summoned the Black Knight copy as witnessed by Hyuuga. Gai fought and defeated the Black Knight puppet and claimed the Ranger Key

While in the possession of the Gokaigers, the Black Knight Ranger Key was used by Gai Ikari (Gokai Silver) on three occasions. After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Hyuuga received his key and became the Black Knight once more.
 * As part of an all-Bangai Hero Gokai Change in the Gokaigers' fight with two Dogormin.
 * When the Gokaigers became the Gingamen while fighting against Basco after Marvelous was incapacitated.
 * As part of a bombardment of changes in the final battle with Emperor Ackdos Gill.
