koidas
Koidas is a fictional character who appears in the Dragon Ball manga and its anime adaptations. He is a minor antagonist encountered by Goku during the early stages of the original Dragon Ball series. Koidas is a member of the very first group of extraterrestrial invaders to arrive on Earth, part of a larger invasion force commanded by the space pirate Frieza's forces. He is depicted as a relatively weak opponent, easily defeated by Goku when he was still a child. Koidas's primary role in the narrative is to serve as an early obstacle for Goku, demonstrating the Saiyan's growing strength and establishing the threat posed by alien invaders. He is characterized by his aggressive demeanor and his desire to conquer Earth. Despite his limited role, Koidas is one of the earliest examples of the diverse alien species that populate the Dragon Ball universe. His defeat foreshadows the greater battles and more powerful enemies that Goku would face in the future. Koidas's design is typical of early Dragon Ball aliens, featuring distinct physical characteristics that set him apart from Earthlings.
