Deunamists

The Deunamists are humans who can bond with the light to become Ultraman Nexus. Although the exact reason for this is unknown, it is suggested that it has to do with the fact the each would face the Space Beast menace regardless of the cost to themselves. All save the First Deunamist Maki Shunichi use the wand like device called the Evolthruster, to transform.

Ultraman The Next

 * Shunichi Maki

Ultraman Nexus

 * Jun Himeya
 * Ren Senjyu
 * Nagi Saijo
 * Kazuki Komon

Dark Deunamists
Besides those that merged with Ultraman, there are the casualties of the battle between Light and Darkness, who were corrupted by the dark side to host Dark Ultras. Although they never merged with Nexus of Next, it was shown that they were also possible vessels for Noa's power, but that they never got the chance to shine in the light.
 * Riko Saida: Komon's girlfriend, was killed by Mizorogi and revived to host Dark Faust.
 * Shinya Mizorogi : Former deputy captain of the Night Raiders, Nagi's former love interest and mentor was corrupted to host Dark Mephisto. Known for his manipulative 'games', after his defeat by Jun, returned without his memories. After Zagi mockingly returned his memories, showing that he himself was just a 'puppet', he went on to redeem himself by saving the third Deunamist from Dark Mephisto Zwei, transforming one last time before giving his life to stop his evil doppelganger. It should also be noted that he was originally intended by Nexus to be the second Deunamist
 * Hiroyuki Misawa : A member of the Memory Police that fell under control of Zagi to host Dark Mephisto Zwei. He had the same powers as first Dark Mephisto and only differs in eye color with Zwei's being red instead of black. Thanks to the interference of the original Dark Mephisto, now on the side of good, Zwei is destroyed by Nexus Junis Blue.
 * Mitsuhiko Ishibori: Although not a Deunamist, he was still the host of a dark Ultra. The analyst of the Night Raiders, in the Mega Flash arc of the series, his behavior began to become suspicious, in the end he was revealed as Dark Zagi inhabiting the stolen body of a scientist associate of Nagi's parents.

Inner Ability
All chosen wielders of Noa's light wield both the EvolThruster to transform and the Blast Shot as a weapon, the channel Nexus' power in human form. Besides these they also inherit the similar abilities that the first Deunamist Shunichi Maki gained during his merger with Nexus prior form. All Deunamists wield the following abilities:
 * Super strength: Each Deunamist possesses greater strength than a normal person.
 * Superhuman Durability: Each Deunamist possesses greater durability and Endurance than a normal person. They are able to endure pain and injuries better than a normal person.
 * Extraordinary Agility and Reflexes: Himeya Jun has made a jump of around ten feet into the air during which he sailed across a distance. He has also fought on even terms with Mizorogi Shinya the Deunamist that was host to Dark Mephisto. Shinya was a Night Raider trained in combat and yet Jun could counter his attacks, also both men had shown remarkable reflexes in dodging and erecting barriers to block energy bullets.
 * ESP: Each Deunamist possesses Extra-Sensory-Perception, allowing them to see events faraway in real time. They also have telepathic abilities.
 * Astral Projection: Nexus' human host can project an astral projection of their Ultra form, this projection can create a Meta-field.

Evolthruster
Evolthruster is the transformation device of all Deunamists, it can be used for more than just transforming into Nexus
 * Shield: Nexus' human host can raise a shield with the Evolthruster.
 * Meta-Field: Nexus' human host can project a Meta-field with the Evolthruster, doing so would cause them to skip Anphans mode and go directly into their secondary form
 * Presence Detection: It most important ability, Nexus himself can sense when Space beasts go active, telepathically alerting his host. When he detects them the lights on the EvolThruster flash.

Blast Shot
Blast Shot is a handheld gun along with the Evolthruster. It has numerous functions.
 * Vacuum Shockwave: Like any gun its purpose is to shoot things, it fire energy blasts that outclass the weaponry used by TLT.
 * Shields: A shot can be used to raise shields at a distance and dissolve Dark Ultra shields.
 * Charged Shot: Charged up like a shot gun, it blasts can vaporize a small Space Beast in one hit.
 * Excorsicm: A special yellow shot can be used to remove pieces of Space Beasts or illusions from a human, safely freeing them from dark powers.
 * Summon: Raised to the sky it acts as flare gun to summon Stone Fluegel, Nexus' spacecraft, where the Deunamists can heal their wounds.

The Mysterious Ruins
Something of note for Nexus is that when his light is not assimilated with a Deunamist it rests within Stone Fluegel which in turns rests within a mysterious ruins, a large castle in a jungle with an upside down stone Fluegel on top. When ever a Deunamist is chosen they begin to dream about these structures and may eventually find themselves in there standing before Stone Fluegel before meeting with Nexus. Also around the ruins are statues and carvings of Monsters, most likely Space Beasts, and past Deunamists as Ultraman fighting Space Beasts. Where these ruins lay is unknown as they are only accessed mentally by the chosen Deunamist, but Zagi was able to send a Space Beast to the ruins where Himeya had his first battle as Ultraman, setting up a meta-field as though it was a real location. However Zagi was later seen destroying the ruins, forcing Stone Fluegal to vacate, in his true form even though in reality he had not yet revived. The true nature of these ruins is never addressed in the series but never the less they are topic of importance to the light.

Stone Fluegel

 * Maximum Speed: Mach 7
 * Length: 2m

Nexus' space craft, it is a stone altar in the shape of sphere on top a downward pointed tower and two side towers pointing down while Nexus' energy core (color timer) is carved on the middle. It usually found in the Mysterious ruins where an inverse image of it stands on top the main temple. It is in here that Nexus resides in an Ultra Dimension when not merged with anyone. Any future Deunamist will be called to the dimension where it resides an called inside the dimension where they meet Nexus who telepathically explains why they were called. Also when called by the Blast Shot, the Deunamist will be placed in the object and it will transform into it transport mode where it become smooth in texture and silver and red, in this form it is faster than any of the Chesters, making them seem slow in comparison. In here the Deunamist can heal their wounds between battles.
