<P> Valerian and Laureline venture further into the infected area, realizing it is actually not toxic and contains some wrecks of antique spacecraft . They reach a large shielded hall where they find the humanoids, known as Pearls, with an unconscious Filitt . Their leader, Emperor Haban Limaï, explains that his people lived peacefully on Mül until a battle broke out in orbit between the human government's fleet and another species . The human commander, Filitt, ordered the use of a doomsday weapon that annihilated both the enemy and the planet . Upon dying, Princess Lihö - Minaa transferred her soul into Valerian's body . A small group of survivors took shelter in a crashed human spaceship . They managed to repair it, and learned of the humans' technology and history . They eventually came to Alpha, where they assimilated more knowledge and built a ship that could recreate their former home . They needed only the converter and the pearl to launch the ship . Filitt admits his role in the genocide, but argues that it was necessary to end the war, and the cover - up to prevent the humans from being expelled from Alpha . Valerian and Laureline disagree, stating that the commander has only been trying to save himself from the consequences for his actions, before Valerian knocks him out again . </P> <P> Valerian hands over the pearl he stole, and Laureline persuades him to return the converter too, ignoring procedures . While the Pearls' spacecraft prepares for takeoff, the other species in Alpha, Filitt's pre-programmed robot K - Tron soldiers attack the Pearls, the government soldiers who were sent to assist Valerian, and their support staff, but are ultimately defeated . The spacecraft departs and Filitt is arrested . Valerian and Laureline are left adrift onboard a still working Apollo Command / Service Module, which is identified by radio technicians as "Destiny 2005", and Laureline finally accepts Valerian's marriage proposal as they wait for rescue . </P> <Ul> <Li> Dane DeHaan as Major Valerian, a United Human Federation soldier and Laureline's partner / love interest </Li> <Li> Cara Delevingne as Sergeant Laureline, a United Human Federation soldier and Valerian's partner / love interest </Li> <Li> Clive Owen as Commander Arün Filitt, Valerian and Laureline's commander </Li> <Li> Rihanna as Bubble, a shapeshifting alien entertainer </Li> <Li> Ethan Hawke as Jolly the Pimp </Li> <Li> Herbie Hancock as the Defence Minister </Li> <Li> Kris Wu as Sergeant Neza </Li> <Li> Rutger Hauer as the President of the World State Federation </Li> <Li> John Goodman as the voice of Igon Siruss, a Kodar'Khan pirate captain and the galaxy's most - wanted criminal </Li> <Li> Elizabeth Debicki as the voice of Emperor Haban Limaï </Li> <Li> Sasha Luss as Princess Lihö - Minaa </Li> <Li> Sam Spruell as General Okto Bar </Li> <Li> Ola Rapace as Major Gibson </Li> <Li> Alain Chabat as Bob the Pirate </Li> <Li> Thom Findlay as the voice of the Pirates </Li> <Li> Mathieu Kassovitz as Camelot on Big Market </Li> <Li> Jonas Bloquet as K - Tron Warrior / Control Room Soldier </Li> <Li> Sand Van Roy as Jessica Rabbit Creature </Li> <Li> Louis Leterrier as Captain Welcoming Mercurys </Li> <Li> Olivier Megaton as Captain Welcoming KCO2 </Li> <Li> Gavin Drea as Sergeant Cooper </Li> <Li> Eric Lampaert as Guide Thaziit </Li> <Li> Claire Tran as Control room Sergeant </Li> </Ul> <Li> Dane DeHaan as Major Valerian, a United Human Federation soldier and Laureline's partner / love interest </Li>
