History
The Magma Aliens were a brutal alien race and the aliens who were responsable for the destruction of Leo, Astra, and Ron's home world of Nebula L77. One of the aliens was sent to Earth to conquer it, but would face Ultraseven who had come to protect the planet. Using his bodyguard monsters, Red Gillas and Black Gillas, The trio brutalized Ultraseven and soon the Ultra's leg was broken by Black Gillas in the process.

At that moment, Ultraman Leo arrived to assist Seven, seeking revenge against the alien for his home's destruction by their hands. Even with the tides of battle in favor of Magma and the Gillas Bros., Leo and Seven managed to hold off the trio. After being beaten down by Leo, Magma and the Gillas Bros retreated for the time being. Sometime after Tokyo is flooded with Tidal Waves, The Gillas Bros. were released again, this time to cause destruction in the flooded city. Ultraman Leo also returned, only to beaten down by the two Gillas Bros until the Magma Alien returned as well to assist them. With the help of Dan's Ultra Willpower, Leo managed to decapitate the Gillas Bros's heads. With Magma being of little match to Leo's superior martial arts skills, Magma fled the scene, leaving Leo still bitter at the trouble they have caused.

Sometime later, another Alien Magma (or possibly the same one previously) appears, disturbing a peaceful monster named Rolan until he was driven away by Gen (Ultraman Leo's human form). Later after Rolan had taken human form and befriended several children by creating pinwheels, Magma returned, destroying some of her pinwheels until he was chased off again by Gen. However as Rolan tried to return home, Magma attacked her once more and nearly kills her until Ultraman Leo arrived himself to protect the kind monster. Again, Alien Magma was overpowered by Leo's skills and met his end after being impaling through the heart with one of Rolan's pinwheels.
