Ferdinand - Wonder Woman: Bloodlines

The son of Pasiphae, the Minotaur "Ferdinand" - as he would become known after a jokey suggestion from Steve Trevor was taken literally - is the original protector of the temple of Pasiphae and the Oracle Fountain at the heart of the labyrinth. 

Forever bound to the place, he is compelled to act as a fierce and ruthless killer, murdering all those who try to access the shrine. 

Attacking Eta Candy and Steve Trevor while they were investigating the Labyrinth, he inadvertently created an entry to the fountain in his haste to gore them, smashing through the walls. 

Seeing that he would not rest while there was the fountain to protect, Wonder Woman destroyed the shrine, reassuring him that he had done well and deserved rest. Free from his duties, he swore his fealty to Diana and her allies. 

Adopting the name Ferdinand, he moved into the Hall of Justice, taking up residency in Diana and Steve's private accommodation.
