With a sound, rather like a battle cry, you hurl yourself at the Pythons mouth. You let your essence explode the second you feel something against your skin.
Your power radiates out slamming into Pythons mouth and burning his insides.
"Ha!" You think. "Take that Hera." Right before you slam onto a Python tooth that goes right threw your chest. Ending your emortal life, instantly.
One benefit to your death, is that your power suddenly expands outwards vaporising Python. The problem is it also vaporises the island and your children.
