Abhibhū(Abhibhu) was the king of Kāśī (Kasi). He joined the Pāṇḍava(s). A prince of Kāśī also participated in the war, and probably he was the son of Abhibhū (Abhibhu). He is mentioned in Droṇaparva (Dronaparva). Dhṛtarāṣṭra (Dhritarashtra)asked Sañjaya about the chariots of the warriors.Among many others, Sañjaya mentioned the prince of Kāśī, and said, his horses were of the colour of Krauñca (Krauncha, a kind of heron), he was young, but tender-bodied, yet a mahāratha (maharatha; a great charioteer) warrior, and the son of the king of Kāśī.
During the battle of Kurukṣetra (Kurukshetra), this prince and his father probably joined the Pāṇḍava(s) —
