Akelons

The Akelons are a race of aliens aligned with the Warp Monarch and recurring antagonists in Chouseishin Gransazer.

History
The first Akelon to arrive on Earth took the form of deceased physicist Karin Saeki and used her disguise to sow discord between the Flame and Wind Tribes, telling the Wind Tribe the other Gransazers were a threat to the planet. However, her true identity was eventually uncovered and she was destroyed by the Gransazers.

However, the Akelon's remains were later gathered by the Japanese government and used to create Clo-Akelon. The Clo-Akelon went rogue and went on a rampage soon after its creation until it was destroyed by the Gransazers.

A third Akelon named Ruby later arrived on Earth, not to attack the Gransazers or humans, but to locate the Communicator, who could contact the Warp Monarch's Will and expose the truth about humanity and the Bosquito to it. However, to conceal the truth, Garban assassins were sent by the Warp Monarch's Earth Invasion Force to kill both Ruby and the Communicator, who was revealed to be Ran Saotome. Ruby was seemingly killed when Gorgion suicide bombed her, but was later revealed to be alive and having been transported to the Warp Monarch's Will.

After Ran contacted the Warp Monarch's Will and revealed the truth that humans were not descended from the Bosquito, Ruby departed with the rest of the Warp Monarch's fleet.
