Damaghosa
Srimad-Bhagavatam
SB Canto 7
SB 7.1.18, Translation:
From the very beginning of his childhood, when he could not even speak properly, Śiśupāla, the most sinful son of Damaghoṣa, began blaspheming the Lord, and he continued to be envious of Śrī Kṛṣṇa until death. Similarly, his brother Dantavakra continued the same habits.
