The air that is inside beings is always in motion. If I have committed an evil act, let it free my breath of life. If I have committed an evil act, let fire, water, space, earth and air free my breath of life.’ Then a sacred voice spoke from the firmament. It echoed in all the directions and gladdened the great-souled monkeys. Vayu said, ‘O Raghava! This is the truth. I am the wind that is always in motion. O king! Maithili is without taint. Unite with your wife.’ Agni said, ‘O descendant of the Raghu lineage! I am the wind that resides in the bodies of all beings. O Kakutstha! Maithili has not committed a crime, even in the slightest way.’ Varuna said, ‘O Raghava! The juices in the bodies of beings owe their existence to me. I am asking you to accept Maithili back.’
-Mahabharata, Draupadi-Harana Parva, Chapter 572(275)
So, the gods like Agni, Vayu and Varuna control the inner organs of all the beings including the Asuras. If they get serious, no asura I repeat no asura would’ve been the victors on the gods of heaven (not even speaking of tridev). One such act was done by Vayu
When you fell down on the summit of the mountain, your left cheekbone was shattered. Because of this, you have been known by the name of Hanumat. On seeing that you had been struck, Vayu, the bearer of scents, was himself extremely enraged and the wind ceased to blow in the three worlds. All the gods were terrified and the three worlds were agitated. The lords of the worlds sought the favours of the enraged wind god.
-Ramayana, Kishkinda-Kanda, Chapter 65
So if they desire Agnic an burn any asura from inside, Varuna can manipulate his body fluids and kill him, Vayu can choke him airless etc. Indra, Surya etc are the presiding deities of parts of body and they can manipulate them as well. So the Asuras are the most overrated characters across the texts.
