Bemular

The first monster Ultraman faced against, the devilish Bemular escaped from being escorted to the Monster Graveword. He fled to rest in a lake in Japan. The next day, Bemular avoided the attacks of the Science Patrol until decided to dish out his blue breath ray. He grabbed Hayata's sub with his mouth and walked out of the lake, the Science Patrol's missilies disloding the sub from his mouth. He shoots his energy ray at the sub, but Hayata transforms into Ultraman. The pair grapple and wrestle around the lake, Bemular barely has an upper hand on the hero. After being thrown into the lake, Bemular tries to escape in his comet form but Ultraman's Spectrum Ray puts an end to him.

He isn't see again until Mega Monster Battle: Ultra Galaxy Legend The Movie, where he is pursued and destroyed by Ultraman Mebius.

• What Could Have Been: The name Bemular was one of the preceding concepts that eventually led to Ultraman. The hero was a bird monster but it was worried the audience would't be able to tell the difference between the good monsters and bad ones. So the monster design was later sold to Nikkatsu, which used it to create the Gappas.

Neronga

Accidentally awakened by young Hoshino, Neronga broke out of the ground and feeded on a nearby power plant. The Science Patrol attacked him when he was feeding on a transmission plant, but Neronga shocked one of their members and turned invisible, escaping. Neronga met the might of the military at his next target, and it was thought he was destroyed. But he returned and reigned damage upon the plant. Hoshino used a laser gun to blind Neronga in one eye. Ultraman made his appearance. Neronga was a bulldog, but he only somewhat holds on. When Neronga's horn is snapped off, it was all over. Ultraman tossed him into the air, and ended his life with the Spectrum Ray.

Forty years alter, he reappears in the third episode of Ultra Galaxy Mega Monster Battle. Fighting and killing Gudon, Neronga preys on ZAP SPACY for electricity, and Gomora was summoned. Neronga wasn't a match against Gomora until he used his invisibility power against him. But Gomora managed to outwit him, and send him packing. Sometime later, Neronga was revived along with Telesdon and Red King. He was the first to charge against ZAP SPACY, but was killed in the crossfire by Telesdon.
