Megarion is a mechanical Space Beast used by the Daruga Imperial Army and an antagonist in episodes 47 and 49 of Genseishin Justirisers.
History[]
Megarion was first deployed by Majin Daruga and Drake to cover their plan to capture Demon Knight's Riser Power. Megarion went on a rampage through the city while the JSDF forces did battle against it and tried to hold it off. The Justirisers soon summoned RiseRoss to join the battle and fight against it, but Megarion was able to hold its own. After Daruga absorbed Demon Knight's power to become Dark Demon God Kurogane and decimated RiseRoss, he recalled both Drake and Megarion.
Megarion was deployed again during the Daruga Imperial Army's next onslaught on Earth using Space Fortress Planet Diglos. It went on a rampage in the city before fighting Shirogane in Ryuto, as the Justirisers couldn't summon RiseRoss to form JustiKaizer due to it still being damaged. However, after Demon Knight and Nolun rebuilt RiseRoss, it combined with Ryuto to form Justi Kaizer and destroyed Megarion.
