Aribunta

Aribunta[1] (アリブンタ) is a species of ant Terrible-Monsters that first appeared in episode 5 of Ultraman Ace. It was created by combining a carnivorous ant and a space monster. The servants of one of Yapool's agents, Giron Man, two Aribunta were tasked with constructing an underground fortress for their master beneath the city of Tokyo, attacking any humans unlucky enough to be caught in their path. After Ace defeated the first Aribunta, the second went with its master to attack the surface while Ace was imprisoned underground. Fortunately, Zoffy came to the rescue, then joined Ace in defeating the two subterranean menaces. Since Aribunta's debut, several other individuals of the species have appeared, almost always as servants of alien beings.
