Idarsa:
A rude kid who was scheduled to fight Trunks in the 25th World Tournament in the children's division. He didn't have a fighting
chance against Trunks as soon as the match started Trunks
kicked him up into the air falling back to the ground unconscious. Thus, losing the match. He is then punished by his mother for losing.
Niko-Chan:
A creature resembling a green butt with a face and antenna who is stranded in Penguin Village along with his servant. In his spare time he either attempts to conquer the Earth, or simply builds a spaceship in order to get back to his home planet. Though his servant is bright, Niko-chan himself is a bumbling idiot. In the Dragonball Manga, he appears briefly giving the victory sign, although his part is bigger in the anime series.
Invisible Man - Yamcha volunteers to fight next & is surprised to learn that his opponent is an invisible man. Because he can't see him, Yamcha spends most of this fight getting slapped around. Seeing his friend in need, Krillin sends Goku off on nimbus to get Master Roshi and a can of tomato soup. When Goku returns Master Roshi throws the tomato soup onto the invisible man, making him visible! Now that Yamcha can see him, Invisible Man is easily defeated.
Dracula Man - This kickboxing vampire first fights Krillin and manages to suck Krillin's blood. Krillin breaks free but loses by ring out. Dracula next fights Puar & Upa. They don't seem to stand a chance until Upa eats a bunch of garlic & starts breathing on Dracula Man. He fights back by trying to bite Puar. Puar turns into a porcupine seconds before and Dracula Man gets a mouth full of needles. Upa gets into a stance that resembles a cross. This freaks Dracula Man out so he turns into a bat and tries to escape. Puar quickly turns into a giant hand a slaps Dracula Man out of the ring.
MUWAHAHAHAHAAAA!!!!!!!!
