Ultraman
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 Hunting
After the Rush Hunters Baltan Battler Barel, Magna, and Garn take the Red King's Plasma Souls, a thunderstorm awakens the Neronga, who attacks the hunters after feeding on a lightning bolt. Garn 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. Garn 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. Garn 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 Garn to shoot its Plasma Souls.
