Yakon

Yakon is one of Babidi's henchmen, and the most feared creature in the universe. He is a gigantic insectoid monster with long claws. He eats light energy and comes from the Planet of Darkness.

When Vegeta destroyed Pui Pui without receiving any damage from him, Babidi sent Yakon to fight them at Level 2 of his spaceship. Two of his men went to get Yakon, but Yakon ate them both. Babidi spoke to Yakon and told him to kill Goku, Vegeta, and Gohan. Goku fought Yakon. Even when Babidi took them to the Planet of Darkness, where it was too dark to see, Goku had the advantage. He turned Super Saiyan so he could see in the dark, but Yakon ate his light energy. Goku came up with a plan to defeat Yakon, and turned Super Saiyan again. Yakon ate his light energy, and Goku maintained his Super Saiyan form long enough for Yakon to eat too much energy and explode.
