Ultraman Hikari (ウルトラマンヒカリ Urutoraman Hikari) is the secondary Ultra Hero of Ultraman Mebius. He was once an excellent scientist who was the chief of the Space Science Technology Bureau of the Land of Light. At one point, Hikari became Hunter Knight Tsurugi (ハンターナイトツルギ Hantā Naito Tsurugi) after his failed defense of the Planet Arb.
In Mebius, Ultraman Hikari, as Hunter Knight Tsurugi, was an embittered Ultra Warrior who sought vengeance against Bogarl for the destruction it caused on Planet Arb. This soon put him at odds with Ultraman Mebius whom he sees as an obstacle that stood before his quest for vengeance. He disregarding lives he unwittingly endangered, including that of his host Serizawa. It took his time with Mebius and Crew GUYS on Earth, coupled with Serizawa whom he possessed regaining his memories and getting berated by Zoffy for his apparent lack of concern for the second life he was given by Mother of Ultra and well-being of his human host that he became humbled and sees his errors and become a better Ultra Hero.
A long time ago, Hikari was the chief scientist in the Land of Light's Space Science Technology Bureau, known for multiple researches and inventions. His greatest research is the method to preserve and revive life forces, which earn him a set of Star Marks on his chest. At some point, he took in Ultraman Tregear under his employment and supervised his creation of the then-unnamed Taiga Spark. Although being used beneficially by his people (such example is with Zoffy healing both Ultraman and Hayata from their defeat), his research also ignited a war between alien races and was misused by invaders for their malicious means (such as Alien Bat reviving the original Zetton into Zetton II). Seeing the horrifying results of his actions, Hikari resigned from the Space Science Technology Bureau and embarked on a journey to study space.
Ultraman Mebius Gaiden: Hikari Saga
The being of light was flying through space on a scientific endeavor. His story began when he was going to the Planet Arb, a completely peaceful planet, that hadn't had a single conflict and had been prospering for tens of thousands of years. Hikari arrived on the planet, being surprised by its beauty. Suddenly, the crystals on the planet Arb started floating, making the form of a humanoid figure.
This being presented herself to Hikari, and believed that he was an Ultraman. Hikari said that he was not one of them, because he was a mere scientist while they were members of the Inter Galactic Defense Force, but Arb trusted him because of his pure heart, which was also like hers. Hikari told the being that he wanted to stay on the planet, but Arb denied him, explaining that the peace on Arb was only temporary and soon a great disaster would occur that would destroy the planet. However, legend foretold of a hero with the Armor of Light would arrive from the heavens at that time and he would fuse with the soil of Arb and be called Tsurugi and would defeat the destroyer. These prophecies were known as the "Prophecy of Tsurugi" which foretold the end of the peaceful planet. Hikari said that he would become a hero and protect Arb and flew off to another planet.
Arriving on Planet King, Hikari started his search for the giant of legend and found a being covered by a red cloak. Hikari told him that he wanted to meet with the legendary giant said to make the impossible possible. The unknown being replied saying that he knew where he was but that he is not sure if the giant wanted to see him. At the same time a great thunderstorm appeared and the being told Hikari that he would meet with the great giant if he could make the rain stop. Hikari, after concentrating for a moment, shot a beam of light straight to the sky, ending the storm and making the sky clear for the planet, so clear that the being had to cover his eyes. Suddenly, the red-cloaked being vanished and a silver-caped giant appeared behind Hikari revealing himself to be Ultraman King, the giant he was searching for. Ultraman King mentioned to Hikari that he had many names, but the name "Ultraman King" was given to him by humans, saying that they are beings from a planet called Earth. Granting him the Knight Brace, Ultraman King warned him about the danger of his heart being corrupted. Hikari decided to leave and head back to Planet Arb, but King told him to be careful, that he might now be drowned by evil desires, 'the clearest water is the easiest to pollute'.
While the Ultra approached Planet Arb, he noticed a strong minus energy radiating from the planet, it was under attack. He arrived to the horrible scene of the destruction of the planet, as many poor beings were being eaten by a terrible beast - a Bogarl. Hikari's heart was consumed by fury and vengeance, via telepathy Ultraman King told him he couldn't fight because of that, but Hikari disobeyed and started fighting the monster, with all his attacks failing. The monster escaped from the field of battle, and Hikari was left there, enraged at his loss.
Upon finding out about his chief's disappearance, Ultraman Tregear ventured to Planet Arb to find Hikari, who was grieving over his failure to protect the planet from Bogarl. He desired revenge, but he wasn't alone in that feeling, he could sense Arb's desire of vengeance too, and Arb's power fused with Hikari, giving him the Armor of Revenge. With his worldview changed, Hikari, with his new found power, attacked his former subordinate before flying to different planets investigating the monster Bogarl, who was taking flight to Planet Earth, to consume it completely.
The events after the first Hikari Saga episode occur throughout the Ultraman Mebius series. Hikari as Tsurugi arrived on Earth, at the time of his arrival, Crew GUYS were having their first battle after long training. Many members of the team died during the arrival of the monster Dinozaur, who easily destroyed almost every member of the team, among them Captain Serizawa who crashed into the monster and supposedly died in the explosion. However, when his ship blew up, the explosion expelled him, and he was taken by Tsurugi, as he found that he needed a human form or host to live on the planet, to get revenge on Bogarl. However, unlike other Ultra/human mergers, when Tsurugi was in his human vessel, the human was completely controlled by him. When Ultraman Mebius was fighting Sadola, he was saved once by Tsurugi, who made many appearances whenever Bogarl appeared. Until one day, Bogarl appeared in a forest, GUYS and Mebius started to fight him, Ryu saw Serizawa nearby and called to him, of course he didn't know who Ryu was, so he still transformed and tried to kill Bogarl, but when he was about to fire his beam, he was stopped by Ryu, who screamed Hikari's host's name, and felt something that made him unable to fight, memories of his host began to awaken and affect him mentally, and was beaten down by Bogarl, but Mebius saved him, and later "destroyed" Bogarl. Serizawa later appeared before Mirai Hibino, telling him to stay out of his way, and revealed him the story of Planet Arb, before vanishing, he then repeated to Mebius the warning to stay out of his way.
Some time later, Ryu was standing in the cliff where he usually spent his time with Captain Serizawa, and suddenly he hears a voice asking him who he was, and when he looked back, it was Tsurugi, in Serizawa's body. Ryu was shocked and saddened, and when Tsurugi told him why he has using Serizawa's body. Ryu demanded the release of Serizawa but the Ultra refused the human and nearly attacked him before Sakomizu appeared. Sensing Bogarl's appearance Tsurugi left to battle. Arriving to find Mebius holding up a transformed Bogarl called Bogarlmons, Tsurugi attempted to destroy the monster but Mebius stood in his way. Mebius warning him that destroying Bogarl now would cost countless human lives, but Tsurugi did not care and attacked the young Ultra. Only the well placed shot be Ryu caused him to pause as more memories of Serizawa began to surface. It was then that Bogarlmons awoke and attacked the blue Ultra from behind, gravely injuring him before it was driven away by Mebius. Disappearing he was not seen again until the next battle with Bogarl. The two joined together to face Bogarlmons together but due to his stubbornness getting the better of him, an unsatisfied Tsurugi was caught in point-blank range of Bogarlmons's death explosion, and was killed. Fortunately, the combination of Mother of Ultra's treatment, and Serizawa's will allowed for him to be revived. Returning to action and helping Mebius defeat Dinozaur Reverse, he was given the name "Ultraman Hikari" by Ryu. After fighting alongside GUYS and Mebius for sometime, Hikari entrusted the Knight Brace to Mebius and departed for space.
Joining the Inter Galactic Defense Force
As he left Earth Hikari came across fleeing objects and was met upon by their pursuer, a Bemstar. The gluttonous monster turned its sights to the Ultra and attacked him. After a short but intense dog fight out in space Hikari knocked the creature to a large asteroid where their battle continued on solid ground. However, Hikari was at a disadvantage without the Knight Brace and the powerful creature eventually began to wear him down. However at the last minute a sphere of red light crashed into Hikari and he found himself in a red dimension, the inside of a travel sphere. This one belonged to none other than Captain Zoffy. Zoffy chastised Hikari for his apparent lack of concern for the second life he was given by Mother of Ultra and by the fact that he was joined to a human who would die with him. He was also curious as why Hikari was fighting since he was not a member of the Inter Galactic Defense Force.
Returning to Earth
As Ultraman Hikari was planning on returning to Earth, he received a distress signal from Planet Arb. Arriving on the planet, he was confronted by a being that looking identical to that of Ultraman Mebius. Noting that Mebius was still on Earth, Hikari and the impostor battled on Arb until the impostor transformed into Hikari's old form, Tsurugi, taunting Hikari by proclaiming that as Tsurugi he was once more powerful by thriving on his vengeance against Bogarl, but has since grown soft since being accustomed by humanity. The Imitation Tsurugi then transformed into Alien Babarue and both alien and Ultra battled.
In the middle of the battle, Babarue froze Hikari in a block of ice, intending on abandoning to him to die on Arb unless Hikari wished to serve him, which Hikari again denied. As Babarue left Hikari to freeze to death, Arb returned to the planet and re-presented the Armor of Tsurugi back to the Ultra, transforming him into the true form of Armor of Revenge; the Armor of the Hero. Fueled by the armor, Tsurugi easily beat down Babarue until the alien fled with his life, vowing to kill both Tsurugi and Ultraman Mebius before disappearing.
Battle Against Alien Babarue

Thanks to Ryu's Knight Brace, allowing Ryu to know that Mirai still alive. Eventually, Ryu, Mirai and the other GUYS Members merged together, giving birth to Mebius Phoenix Brave.

"You guys are responsible for making the future of this planet."
- ―Hikari's final words before leaving.
When Ultraman King was alerted of Juda's revival, he mobilized Hikari, Leo, Astra, and Ace to stop the emperor. Hikari invented the Knight Timbre, which is capable of sealing the emperor and made his way to Earth (Ginga's universe), where he would find the weapon's destined user. He appeared at Sho/Ultraman Victory's battle with Aribunta, underground, stunning it with his Knight Shoot and Knight Beam Blade.
Hikari gave Ultraman Victory the Knight Timbre, which he used to transform into Ultraman Victory Knight and finish Aribunta for good. He entrusted Victory with the weapon and his mission to seal Juda in space.

Ultra Galaxy Fight: The Destined Crossroad
During the meeting with the Ultra League and Tri-Squad after the skirmish on Planet Ebil, Hikari noted the need to identify the unknown constitution of the Absolute Particles before a rescue attempt could be made.

They were later joined by Justice, sent to them on the order of Delacion. The team infiltrated the Kingdom and split up to search for Yullian, agreeing to rendezvous back at the Eldora Tower later, but unfortunately came across some resistance.
While searching around, Hikari and Victory paired up but were attacked. Belial fought Victory in a clash between the Beliarok and the Shepherdon Sabre while Tregear battled Hikari wearing the Hero's Armor. Each of them fought rather evenly with their opponents until Astra managed to find and rescue both Yullian and Ultraman Regulos, with Victory and Hikari managing to escape from the duo when the former used his Ultlance to access the EX Red King Knuckle, blowing Belial and Tregear back. The team waited for Astra to arrive, delayed by an attack from Absolute Diavolo. With the Absolutians closing in and their way home shrinking by the second, things seemed grim until Astra arrived with both Yullian and Regulos with him. Despite all their hardships, the team managed to leave the Kingdom and their mission was a success.
After the rescue squad managed to escape, they arrived on Planet Blizzard pursued by the Absolutians and their forces, only for them to be met with a large gathering of Ultras.
