I'm more interested in how Indra will look animated.

Based on his description in the LN, I think he'll look like an "army-guy" wearing sun-glasses and a hawaiian shirt.

I say "army-guy" bacause he's described having a "buzz-cut" hairstyle, which is typical for soldiers, and he is the God of War in Hindu Mythology, so it fits with the "soldier" theme.
