Indra is a Tyranitar, a Deity that is not part of the Divinity's counsel...Her power is such that she can be classified as a Goddess, but Her means of Ascension is as yet unknown by the Divinity and needed to be ascertained...
Surya was the Goddess chosen for that job, and to Her alarm, Indra was even more frighteningly powerful than She had first gauged.
To hear Her tell it Herself, Indra was just a gym rat who got such sick and epic Gainz that She achieved Apotheosis purely by the strength of Her own back...and it's hard to contest Her Intimidating results. Worse, She intends, metaphorically or literally, to "bench the friggin' galaxy one day" and will do anything and everything in front of her to achieve that goal.
Everything, and everyone, else is so utterly beneath Her that they might as well be dust under Her feet.
Indra's normally jet-black hair has a curious tendency to shift hues and coruscate a furious gold when She gets particularly excited to fight.
Scarce are the ones who get to live to tell of this awesome phenomenon.
