• His defeat has been ritualized every spring and Slaying the Dragon, found on ancient texts, are recited at the Puruli festival.

In one story he defeats the storm god, and then the same storm-god lures him and his children from their lair and kills them with the help of other gods

A variation of the story has the hero Hupasiays getting them drunk and then killing them with the thunder-god's lightning and the help of the goddess Inaras.

In another tale, Illuyankas defeated Teshub in battle and Techub went running to Inaras who got Illuyankas drunk at a feast, bound him and let Teshub and his friends hill him.

In yet another variation, Illuyankas maimes the Weather God and sends him running to the goddess Inaras (the only one to answer his pleas for help) who then, with the help of the hero Hupaiyas (and after sleeping with the hero) she throws a huge banquet. The dragon and his retinue are so stuffed and drunk that it is easy for Hupasiyas to tie them up so the Weather god could kill them.

Storm God Feud:
This is a short tale of a dragon who started feuding with the storm god (Teshub?). At first he won and took the storm dragon's heart and eyes.
The storm god then went to an oracle who told him that to get his heart and eyes back, he'd have to have a son by a mortal and when that son was to be married, the storm god was to ask for his heart and eyes back. But he was not to tell his son that he was the storm god.
This the storm god did, and when his son grew and fell in love with the beautiful daughter of the dragon (unbeknownst to him), he did as his father requested and asked for the eyes and heart of the storm god.
The dragon obliged and when the storm god got his heart and eyes back he killed the dragon, his son's father-in-law.
The son was so distraught by this killing and his place in it, he killed himself.
