While Sun Wukong claims that Indra doesn't harbor any evil intentions within him, his actions of supporting the Khaos Brigade, specifically the Hero Faction from the background makes this a very doubtful statement. Many fears him and untrustworthy towards him, particularly Azazel. He is also very arrogant, as he openly threatened to eliminate Issei in front of Azazel, he also stated that that the only ones who can use the name of 'Heaven' is his own religion (referring to himself), his ability to see, read, and determine an individual's true intentions and colors are the reason why he does not easily trust others particularly the leaders of the Three Factions. In the Azazel Cup, he wore a Buddha armor during his match against Mahabali. In the anime, he has the vermillion mark on his forehead.

He wears circular sunglasses, an aloha shirt, and has a jewel around his neck when in his leisure. Indra has the appearance of a man with a buzz-cut hairstyle with greenish brown hair color and lavender eyes.
