Wildebeest is the name of different characters from DC Comics.
The first Wildebeest is a poacher and mercenary who was an enemy of Chris King and Vicki Grant.
The original Wildebeest was an unrevealed supervillain who set up the Wildebeest Society, a criminal cartel who conducted various underhanded affairs for financial gain. Although the Society was made up of many members (some of them having previously worked for the H.I.V.E.), only one Wildebeest ever operated publicly, giving the illusion that all of their crimes were being committed by a single individual. The thinking behind this was that there would appear to be one villain, but his M.O. would seem to change with each crime making his moves impossible to predict.
In his first encounter with the Teen Titans, Wildebeest first appeared where he had framed Starfire for murder. He used a robot likeness to antagonize Starfire and then swapped it out with a suit containing a dead man.Nightwing found the evidence to prove Starfire's innocence.
Wildebeest's second attempt to destroy the Teen Titans involved him breaking into S.T.A.R. Labs and capturing the pregnant Mother Mayhem whose baby would become the new Brother Blood. Wildebeest later set up a group of second-second string villains (consisting of Gizmo, Disruptor, Puppeteer, and Trident) and caused the people to think that a new supervillain group was formed. While Mother Mayhem gave birth to her child, the villains were defeated while Wildebeest escapes.
Wildebeest later took control of Cyborg (which caused people to think that the Wildebeest Society had connections at S.T.A.R. Labs) and used him to attack the Teen Titans.
In time, the Wildebeest Society fell under the sway of the former New Titan Jericho (who himself had been possessed by all of the disparate souls of Azarath). The corrupted Jericho took control of the Wildebeest Society. Under the leadership of Jericho, the Wildebeest Society began conducting a series of genetic chemical-organic experiments to create the perfect host bodies for the evil spirits to possess. They began their genetic alterations on humans and animals. All of their experiments failed except for the human/panther hybrid labeled X-24 (who later became Pantha) which escaped and vowed vengeance on the Wildebeest Society. Jericho then staged an elaborate "Titans Hunt" to capture current and former members of the Teen Titans in order to acquire host bodies to contain the souls of Azarath when their experiments were failing to yield results. The Titans were rescued by Pantha, Arella, Phantasm, Red Star, and Jericho's father Deathstroke. At the conclusion of this affair, the Wildebeest Society was destroyed and Jericho was killed at the hands of Deathstroke when Jericho broke free from the possession and begged his father to kill him. The final experiment by the Wildebeest Society called Baby Wildebeest fell into the Teen Titans' custody.
