Anton was born in South Africa and grew up as a racist, but deep in his mind he had feelings for black people which he suppressed for a long time.
Anton Pretorius first met Ramonda after she was imprisoned for participating in a protest. He returned every day to see her and freed her when he gave in to his obsession with this black woman. He then made her disappear via paperwork/bureaucracy and brought her to his mansion were he kept Ramonda hidden from the public circles. Pretorius took more and more risks to perpetuate his compulsion over the years. He sent photos to T'Chaka to make it appear that Ramonda had run off with another man.
Anton Pretorius sexually abused Ramonda over the years he kept her at his house. He would calculatedly touch her until her body reacted and a need aroused in her body and mind.
Pretorius was contacted by Patrick Slade who told him that he knew about him and Ramonda. Pretorius also found out about the Black Panther soon coming to Slade, who wanted some money to keep his mouth shut.
Pretorius sent out his gang of mercenaries led by Elmer Gore to kill Patrick Slade and Black Panther at their meeting.
Anton Pretorius met with Percy Boraine after the taping of another "Naked Exposures" show. This show's topic was the invasion of the Black Panther in South Africa. Pretorius wanted to meet Percy as soon as he heard of the attack on him by the Black Panther. He told Percy that the attack against him was an international incident and showed him pictures of the Black Panther, whom Percy recognized as his attacker. Pretorius assured Percy that troops were sent out to get the Black Panther (after some right winged words against Americans and other foreigners who wanted to interfere in South African affairs through sanctions and other punishments). In the evening Pretorius told the nation on TV everything about the Black Panther from his being the king of Wakanda to his illegal entrance into South Africa, and he even showed pictures of him. Pretorius assured that the parliament would take care of this situation.
Pretorius asked on TV for help from the citizens of the nation. He introduced Doeke Riebeeck to the public as the man in contact with the troops. He talked about further attacks of the Black Panther against law and order and stated that he was the son of T'Chaka. He wanted everyone to report sightings of the Black Panther to local police or Security Forces and assured everyone that the bloodshed of the Panther would soon be stopped if they all worked together.
In the news it was stated that Pretorius denounced the Wakandans' lack of candor after a conference where W'Kabi, the head of Wakandan court security, denied that the Black Panther was in South Africa.
Anton Pretorius and Doeke Riebeeck had a heated discussing about the way the troops were allowed to proceed against the Panther. Pretorius tried to explain that this could become a real problem for them if the Black Panther was killed by their troops (while Pretorius checked on glass plate on his desk that was broken by Riebeeck before). He told Van der Merwe that he would like to know the reasons for the Panther's actions as much as Van der Merwe did, and Doeke once again screamed at him. He then told Riebeeck that the wish of the cabinet ministers was that the violence stopped without causing more deaths. He told him that the Panther could be killed if they had to do so. Pretorius asked Van der Merwe if he didn't want to heal and gave him the okay to go with Riebeeck when he wanted to. Left alone in his bureau Anton Pretorius looked broken like the glass plate on his desk because he thought the situation would get far worse.
Pretorius was in Capetown and kept contact with Doeke Riebeeck over walkie-talkie. He was informed about the involvement of Black Panther in the riot the night before in the Black Township of Pretoria. He wanted to stay informed about their search for the Panther.
Anton heard the gunfire through the walkie-talkie and wanted to know from Riebeeck what happened. Riebeeck stopped to report his actions to Pretorius and broke up the contact.
On TV Pretorius talked about the newest incident with the Black Panther and blamed the death of the young boy Theodore Olebogeng on his actions. He also told the public that the troops were already closing in on the Panther and wished them a good night.
In his mansion at Devil's Peak, Pretorius took Ramonda away from the opened window to not expose her to a strayed bullet and then closed the door of the balcony.
Pretorius handcuffed Ramonda to her bed and locked the balcony's door. He then left her to check on the latest report on security measures and told her to not be depressed if this ended badly for the Black Panther. Pretorius later returned to her room and was in a panic because he couldn't contact Gore anymore and servants told him about madness outside. He met Black Panther for the first time. The Panther carried him to the balcony and threatened to drop him, but Ramonda stopped him. Pretorius told the Panther that he always liked his courage and independence. He opened Ramonda's shackles and she threw them in his face. He told Ramonda that he loved her and asked her to stay with him. She punched him in the face and left with Black Panther. Anton Pretorius stood up on his balcony and was now alone.
