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. 

Officer Mick Rory - Justice League

A member of the C.C.P. D’s Specialised Crime Unit, Officer Mick Rory was the partner of Leonard Snart. Together with Sergeant Samuel Scudder, Detective Mark Mardon and Officer Axel Walker, he was tasked with hunting down Jonathan Allen and Rhonda Pineda, a pair of serial killers who had been terrorising Central City for months. 

Finally capturing Jonathan Allen, the pair transported him to Iron Heights. Although he argued that Allen should be killed without delay, he relented, agreeing with Snart that the pair should not be granted a quick death after all the pain and suffering they had caused others. 

Before they could reach Iron Heights, Pineda stages a jailbreak for Allen, smashing into their police transport with a garbage truck. Both Rory and Snart are knocked unconscious from the impact. Seeing that they are still alive, the pair decide to take their revenge and have some fun with the officers. 

Waking up in the abandoned basement of S.T.A.R Labs, Mick is enraged by Pineda talking about his family and newborn daughter, vowing to kill her if they hurt his loved ones. However, she goes on unperturbed, proposing to them a wager - a brawl between the two police officers, and the winner's family survives. Desperate to keep his family safe, Mick eagerly accepts, beating Leonard to death. 

Crying over his friend's lifeless body, Rory pleads that they keep their word, only to be shot in the head by Allen. 

Unbeknownst to the killers, both Rory and Snart had been fitted with body cams, heartbeat monitors, and homing devices, alternating the C.C.P.D to their precise location.

Officer Leonard Snart - Justice League

The partner of Mick Rory, Officer Leonard Snart of the C.C.P.D Specialised Crime Unit was part of a task force dedicated to capturing the serial killers "Johnny & Ronny", aka Jonathan Allen and Rhonda Pineda. 

After months of senseless bloodshed and destruction, they finally capture Jonathan Allen. While Rory wants to execute Allen then and there, he is talked out of it by Snart, who wants to take them back to Iron Heights and kill Allen and Pineda slowly, making them pay for their fallen friends and comrades who had died at the killers' hands. However, before they can reach their destination, they are run off the road by Pineda in a stolen garbage truck. 

Coming to hours later, Snart finds both himself and Rory tied up in the basement of the abandoned S.T.A.R. Labs building. Unable to break free of his restraints, Pineda tells the two officers that only one of them will survive the night, threatening to kill their families if they do not fight to the death. 

Seeing through her lies, Leonard tries desperately to dissuade Mick from engaging in their cheap little games. However, his pleas are ignored, and he is beaten to death by his partner. 

His death triggered a tracking device, alerting his fellow C.C.P.D offers to Allen and Pineda's location.
