Sahastra ravan

Durvasa was the form Shiva took when cursed by Anasuya whom the trinity dared to test.

He is the originator of Tantra and is Shiva's destructive energy.

In Jaimini's Sahasramukharavanacaritam from his Mahabharata, Durvasa being insulted at the yagya of Mandhata produces sons with

1. thousand heads, 
2. hundred eyes, 
3. hundred bellies and has them conquer the three worlds. 

Rama and all the gods attack, and are "killed" by them. Then Sita assumes a wondrous form

with the help of five-headed Hanuman

uses mantra-infused grass pillars to consumer the demons from within as they cant be killed by weapons, while Hanuman devours the rakshasas.
