The figure and characteristics of Indra as depicted in Mahābhārata-Rāmāyaṇa-Purāṇa is completely different from that of his acts and manners as described in old Veda and Brāhmaṇa treaties. Indra in/of Veda the greatest warrior, he is slaughter of Vṛtra, Namuci, Śuṣṇa, Cumuri, Dhuni, Śambara, Pripru, Vala, Arbuda, Kuyava — killing these dangerous demons/Asuras he is celibrated as a greatly honoured hero of Devaloka (Heaven) in Veda and Brāhmaṇa books. Hundreds of his deeds are appraised in Ṛgveda — Indra strengthened the painstriken loose/weak Earth, created the Antarīkṣa, settled the Mountains, thundered the Sky, created Fire in the Cloud, he made the entire Viśva-bhuvana (World ) —
yaḥ pṛthivīṃ vyathamānāmadṛṃhat

yo antarīkṣaṃ vimame varīyo

ya Śambaraṃ parvateṣu kṣiyantaṃ

yaḥ śataṃ śambarasya puro vibhedāśmaneva pūrvīḥ/
Paṇḍitas proclaimed, the name ‘Purandara’ is famous for this fest of Indra in Mahābhārata-Rāmāyaṇa-Purāāṇa. Other power of Śambarāsura is Māyā (Dissimulation). Without the power of Māyā or deceit it was not possible to hide himself for a long period of forty ears from Indra.
