Neronga (ネロンガ) is an ancient kaiju that first appeared sleeping beneath a well near Kazumi, only to awaken and go on a feeding rampage but was stopped by Ultraman. A second Neronga appeared on Planet Boris.
Subtitle: Invisible Monster (透明怪獣 Tōmei Kaijū)
Awoken by man and bellowing in hunger, Neronga emerged from underground, and headed for a nearby power plant to drain the energy. Soon the Science Patrol is called in to locate the monster. On arrival, Neronga was invisible and attacking a Transition Station, attacking and the Science Patrol began to open fire with their lasers, only angering the beast, who struck back with a beam of electricity. The crew survived, but Neronga escaped, looking for more energy.
Predicting Neronga would attack at another power plant, the Science Patrol forced the monster to become visible with their weaponry. Enraged, Neronga fought back by hurling a huge ship, destroying the entire plant and resumed attacking the Science Patrol with his electric bolts. One of the Science Patrol members managed to blow out one of Neronga's eyes but this only angered the monster even more. Hayata transformed into Ultraman and manhandles the beast, beating him like crazy, but Neronga still fought back. Before long, Ultraman tossed the monster into the air, and finished it with the Specium Ray.

Ultra Galaxy Mega Monster Battle
Neronga reappeared in episode 3 of the series, Ultra Galaxy Mega Monster Battle.
Neronga was first seen battling against a Gudon. At first it seemed Gudon had the upper hand, but when Neronga used his invisibility technique he outsmarted and distracted Gudon long enough to kill him with his electricity bolts. After the match, Neronga proceeded to feed on the electricity of a nearby radio station. The next day, Neronga was wandering the area looking for more electricity, ultimately setting his sights on the ZAP SPACY where the monster attacked them looking for more electricity. Rei summoned Gomora to do battle against the monster and it seemed Gomora had the upper hand, but Neronga used his invisibility technique against to try and distract Gomora to kill him. Listening closely to Neronga's movements, Rei guided Gomora into attacking the invisible Neronga and successfully destroyed the monster as a result.
Sometime later when the monster Bullton appeared before ZAP SPACY, Neronga was revived alongside Red King and Telesdon. Neronga was the first to charge into battle against Gomora and Litra. While Telesdon fought Litra, he accidentally killed Neronga with his flame breath.
- Neronga was created from a reused Geronga suit. Interestingly enough, Geronga himself is a direct tribute to Neronga, since Neronga pre-dates Geronga by nearly 40 years.
- And just like the original Neronga, the suit from Ultra Galaxy would be used to make Magular.
- During the opening credits to the series, Neronga is seen battling Telesdon, even though both monsters worked together when they were revived by Bullton.
- From this series omwards, Neronga is changed to a biped whereas the original was primarily quadrupedal.
It is evidently that Neronga's Spark Doll was collected and used to create Cyber Neronga (サイバーネロンガ Saibā Neronga). The monster's design was used by Xio as one of their target practice, alongside Cyber Zarab.
Cyber Neronga reappeared as a Cyber Card in the final episode of Ultraman X. After Ultraman X spoke out to Gomora and striked Greeza right in the center of his chest, Neronga, along with all of the other Cyber Cards, traveled to X and united with him. Cyber Neronga's power was used to help form the Hybrid Armor and power up the Ultimate Xanadium to defeat Greeza once and for all. Neronga, along with the numerous other Cyber Cards and Spark Dolls, then appeared and thanked Daichi as he thanked them.
Neronga returns in this series, making its first in-suit appearance after 10 years. Neronga was summoned by Saki Mitsurugi, who had recently taken over Aizen Tech. She used Neronga to redirect electrical energy from a nearby electrical tower to Aizen Tech's premises, for purposes unknown. Ultraman Rosso and Ultraman Blu arrived to deal with Neronga, but they were both caught off guard by its invisibility powers and electrical attacks. After giving them a beatdown, Neronga was recalled by Saki, reverting it back to its R/B Crystal.
When Katsumi Minato and Isami Minato confronted Aizen Tech's new president while she was talking to Asahi Minato, she revealed herself to be the one summoning monsters recently as she unveiled her special Gyro to call Neronga into action again. The brothers transformed to fight, and this time they thought of a way to counter its invisibility, which was by covering it in sand. The brothers then used the power of the Kiwami Crystal to transform into Ultraman Ruebe, who finished it off with the Ruebe Kourin Shot after a brief fight.
- Suit Actor: Hiroyuki Arai
- A new suit was constructed for Neronga's appearance in this show.

Neronga appears in two mini-videos for this video game to act as sport for the main alien trio. His head has plasma crystals that, when destroyed, act as game points for the player.
After the Rush Hunters Barel, Magna, and Garm take the Red King's Plasma Souls, a thunderstorm awakens the Neronga, who attacks the hunters after feeding on a lightning bolt. Garm uses the Hawkeye Shot several times, but to no avail. Magna spies its footprints, and attempts to use Force Sabre, but bounces off the creature's forehead and flies into a stalagmite. Garm then tells Barel and Magna that Neronga can only stay invisible for a certain amount of time after absorbing some electricity. They regroup as Neronga absorbs another lightning bolt and vanishes. Garm then gives the others his plan, which is put into action. Barel uses his copies as decoys to make the Neronga shoot out all its energy. Magna uses his metal arm as a lightning rod, to prevent the Neronga from absorbing any more lightning. As soon as Neronga becomes visible, Barel uses his scarf to bind Neronga's nose horn and trap it long enough for Garm to shoot its Plasma Souls.
Plasma Killersaurus Hunting
