Ghatotkacha the pot-head

Mahabharata Adiparva Hidimbavadha-parva section 158
Sri Sadgurubhyoh Namah

Hidimbi pleads with Kunti and Yudhistir that she be allowed to marry Bhima. Yudhistir gives permission to Hidimbi and says "Let Bhima after his morning ablutions go with you everyday and sport with you. But you must allow Bhima to return by sunset". Then Bhima says to Hidimbi, "O Rakshasa woman, I will live with you as commanded by my elder brother till you concieve a child, after that I will leave you".

Agreeing to this arrangement, Hidimbi takes Bhima and flies to a far off place onto a mountain, unreachable by humans. They sport like that for many days to the heart's content of Hidimbi. Everyday Bhima used to return to Pandavas by sunset.

Hidimbi concieves a male child, who has pointed ears, long nose, bald head, large lips in copper colour, red eyes, with bulging biceps. He doesnt resemble human at all eventhough born of a man. Rakshasas grow up into adults within an hour of their birth. This male child grows up quickly within an hour into an adult and he bows to his father and mother reverentially. He learns how to use all kinds of weapons.

Due to his head being bald like a Ghata (pot) he is named as Ghatotkacha (pot-headed).

Ghatotkacha promised his father that in need of hour he will come to him and went away northward.

Indra is the creator of this pot-headed monstor who is a fit reply to the dart that can kill anyone that Indra himself gave to Karna.
