Indrajit appeared in the epic of Ramayana as the son of Ravana, the king of Lanka. His original name was Meganada for the battle cries he made sounded like thunder. He was named Indrajit by Brahma when he defeated and humiliated the king of daevas Indra, of whom Brahma asked to be released, and in return granted Indrajit many celestial weapons, and the boon of invincibility.
Indrajit acts as one of the five demons that controls the Pentalpha system. Players can align with him to fight against mobs representing the other demons within the system. Those fighting against him will face waves of demons belonging to the Earth Mother Race, Dragon God, and Brute races.
By acquiring enough power for him, players can obtain the ability to fuse him in a special fusion of Zouchouten and Rakshasa.
Known as Meganada and being the one of the first two demons (Atma Avatar) transformed since the incident that blackened the sun. The identity of the host is not known. After his defeat, the Karma Society sealed him in a large lumb of transparent material deep inside the EGG laboratory facility. From there Jenna Angel extracted enzymes and produced the demon virus so the one who injected with it can survive under the black sun and not petrified by its malignant radiation with the countereffect that is able to transform into a demon with unsuppressible desire to devour the others.
During Jenna Angel's uprising, she orders her follower to release Meganada from EGG in order to wipe out the Lokapala members who are defending the power plant entrance. Jenna finds her plan amusing which coincides with the myth of Meganada defeating Indra, Roland's Atma Avatar. In a suicide mission, Roland and Argilla overload the reactor, so the explosion kills Meganada along with them.
When the player party ascends to the Sun, Meganada's solar data blocks the last passage to God. His data is eventually eradicated and dissolved.
Meganada will change aspect with different resistances and skill set depending on how much the player has depleted his HP. He begins with his "physical aspect" with his shell closed, and switch to "magical aspect" with his shell opened.
When Meganada's remaining HP is below a quarter, his pattern will be more random. He may 1) use Black Bhakti and his ultimate attack in the same turn instead of using these 2 skills in separate turns or 2) use Black Bhakti in the previous turn then change aspect and use his another ultimate attack in the following turn.
Meganada possesses 2 turn icons during this aspect. When player has depleted his HP by about 20%, he will use Moksha to switch to magical aspect then immediately followed by Dekunda to negate all debuffs on him.
