Rosabelle Mendez was New York University student, who was kidnapped by Maxwell Lord, then sold to Wildebeest Society. Steve Dayton as Crimelord was obsessed with experimentation which led to the creation of the technology that turned Rosabelle into the cat-hybrid by the Wildebeest. The new Wildebeest Society began their own genetic alterations with animals and humans to make a suitable host for the true Wildebeest. By altering the humans/animals they experimented on their bodies would become strong enough to withstand the force of the true Wildebeest. All the experiments died except one and that was subject X-24/ Pantha. She managed to free herself and escape but would return to exact her revenge on the people who created her.
Pantha was created by Marv Wolfman and Tom Grummett. She appeared first in The New Titans #73 as a shadow and fully in The New Titans #74.

Meeting the Titans
After her escape she started to pick off Wildebeests one by one. After one of the attacks, she heard of a mugging on the streets; at first she tried to ignore it but then she remembered that no one helped her, and that got her where she is now. She jumped down from the roof and attacked the mugger, but before she could kill the last man, she herself was attacked. The attacker was Deathstroke, Pantha knew who he was and what he was after. She said that they have similar goal, but their methods are different, she wanted all of Wildebeest dead. Pantha made another try to attack Wildebeest base, but was confronted by Deathstroke again. After a quick argument, she escaped him, and met Phantasm, who too wanted to join her. Pantha wanting to avenge herself alone, took the first chance she got to slip away. Inside the base she found Number 1 of the Wildebeests. He is Pantha's primary target and she leaped to attack him, but to her surprise she was taken over by him, as the Number 1 was Jericho. When she was knocked unconscious, Jericho left her body and started to tear the base apart. Pantha recovered in time to escape to destruction and agreed to go to the Titans Tower. In the tower she got into another fight with the Titans, and decided to leave, but she was stopped by Nightwing. She was tied up and left that way, even when the Wildebeests attacked. She was freed by the Phantasm and she joined the fight. They manage to escape before the tower exploded. Pantha joins the Titans in their mission to Russia to see who was blown up in the rocket.

At the same time Donna Troy returned to United States; Titans went to her only to witness her disappearance along with Nightwing's. They abandoned their quest to hunt Wildebeests and chased leads about Donna Troy. Pantha at first wanted to leave, but for some reason changed her mind and joined others in the search. After the War of The Gods; Donna Troy returned and Titans concentrated on finding Jericho. Their only leads were painted pictures, and it was Pantha who figured out that all the painting were painted from one location, and if they find the building, they find Jericho and their friends. In that house they found a door to Azarath, where Jericho was finalizing his plan. Titans attacked the compound and tried to rescue Nightwing, but for their surprise Jericho was inside him, and Titans were captured. Jericho tried to give their bodies to the souls of Azarath. Before being killed by his father Jericho almost succeeds in that, but when he died, those Titans who were unconscious were taken over by the souls. That didn't last long as Raven summoned all the souls to her for more power, but it still wasn't enough to fight her own mother. Titans won the battle and the Wildebeest Society was ultimately destroyed. Pantha returned to our world alongside the Titans. Jericho’s house also imploded, and in its place appeared Phantasm with Baby Wildebeest. Other Titans wanted to keep the baby, but Pantha was against it from the start. One time Baby Wildebeest was playing outside and a car drove towards him, Pantha decided to do nothing and just watch him die. The car hit the baby, but it didn’t even hurt him. In time Pantha started to realize that the baby and she are the same, both victims to Wildebeests. For some reason Pantha was always left to babysit the kid, and she didn’t like it one bit. But one time when Pantha got away from the child, Titans were soon called back to the Steve Dayton's estate, as Baby Wildebeest was causing damage. Baby Wildebeest only calmed down when he got to hug Pantha, who he thought to be his mother. Trouble with the baby was interrupted by the hunt of Deathstroke and then the threat on Donna Troy’s life. Fight ensues between New Titans and Team Titans, but Lord Chaos intervened and kidnapped Donna. In another fight with Team Titans; Baby Wildebeest grew big out of anger for the first time. Now that Lord Chaos had born in this timeline, he returned to kill his father. Donna returned as a goddess to fight him and Titans were caught in the middle.

Technis' main goal was to take over earth. To gain Titan's trust they offered Pantha to restore her memories, but she got only partial flashes of faces. After learning Technis true plan, Titans try to fight them, but it is Cyborg who wins the fight by merging with the Technis and flew into space after he teleported Titans back to earth. Pantha managed to find the person who she saw in her memories, but when she got to her house she had been abducted. Pantha then confronted Steve Dayton about it and he admitted getting rid of her.
