Méche, son of the Morrígan, was prophesied to bring about the end of the world. He is described in the Dindsenchas as having three hearts with three serpents, and if death did not befall Méche those snakes would grow until all of Ireland was a wasteland.
The hero Mac Cecht kills him by first slaying Méche, then burning his three hearts, and the ashes then cast into the River Berba. When the hearts entered the river, the river boiled and killed all the creatures there.
Interestingly enough, I couldn’t find anyone who knew any etymology on Méche. Yet outside the Dinnshenchas, little is known about this entity so perhaps that isn’t so surprising.
