Koola first appears in Movie 5-Battle of the Strongest. He watched his brother, Freiza, destroy Planet Vegeta. He saw baby Goku's saiyan space pod fly by his ship. He let the ship go unharmed only bacause he thought that it was part of Frieza's plan. Upon learning about his brother's death by the hands of some "Super Saiyan", he landed on Earth for revenge. Koola, like his brother Frieza, has a tiny army. Koola's is named "Koola's Armored Squadren". Instead of 5 members, like the Ginyu Force, Koola's army has only three members. Later on, Koola's army is destroyed. Koola is then forced to fight. He fights Goku but they are to evenly matched. Koola then transforms into his second and final form. He fights Goku and proves himself to be the better of the two. Just then, Goku transforms into a Super Saiyan. Koola is no match for Goku now. Goku blasts Koola with a huge Kamahamaha. Koola is then hurled into the sun and screams "Freeza wasn't the only one who had a lot to learn!". Koola then burns up in the sun and dies. Koola appears once more in Movie 6-Attack! 1,000,000 Power Warriors. Koola attaches himself to a spaceship to form the "Big Gheti Star". He then attaches himself to the new Planet Namek. He reveals himself to Goku and the gang in his new "metal" form. He can regenerate his lost limbs just like the Nameks can. He seems unbeatable until Vegeta and Goku give it thier all and destroy him. Then they realize there are more than one. A cliff is now lined up with one million "metal" Koola's. Vegeta and Goku blast off but get caught by the Big Gheti Star. Then they see him. Koola's head survived the battle back on earth in Movie 5. Koola then starts to drain all of Goku and Vegeta's energy. Koola stops and says that he vever thought that Super Saiyans had this much energy. Goku and Vegeta, half dead, start emitting more and more energy. Koola tells them to stop but they refuse. They emit way too much energy. Koola then explodes because of too much energy and dies.
