The Asura are splintered into two main groups: the Mythborn Adityas led by Varuna, and the Danavas, led by Titan Avatar Vrtra. However, both types of Asura have members who are not affiliated with the leader the majority follows.
The Asura are very numerous, intelligent, and organized. Though enemies of the Deva, they are not malevolent - instead being more driven by passion than the Deva, whom they consider sanctimonious.
They feel kinship with the Rakshasa, who are also past their glory days of openly challenging the Deva.
