Catseye appeared as part of the "Hellions" entry in the Official Handbook of the Marvel Universe Deluxe Edition #5.
Emma Frost took advantage of the New Mutants' emotional turmoil after an incident where a cosmic being called Beyonder had actually killed them and then brought them back to life. She persuaded the current headmaster of the school, Magneto, to send the students to the Massachusetts Academy for psychic counseling. There, she promptly accepted them into the ranks of her Hellions. Catseye shared a room with Rahne and the two of them became close friends. The two teams became quite fond of one another but were separated when Magneto realized that his mind had been manipulated by Empath and the decision to release the students had not been fully his.
Catseye and Wolfsbane would meet in a formal dress party sponsored by the Hellfire Club. The two sneaked off, left their dresses behind and romped in their animal forms.
Later, the two teams would clash high about Manhattan. Both had learned about the existence of Bird-Brain and neither team wanted the other to have him. The Hellions lose the encounter. Furthermore, an accident sends Catseye and Roulette plunging to the streets. Roulette's power saves them both, allowing them to land safely in a store canopy.
The White Queen would later cause a confrontation between her team and the New Warriors. This was over the fate of Firestar, a member of the Warriors who used to be a part of the Hellions. The battle, held in the New Warrior's penthouse, came down to a game of numbers and Catseye scored one for her team by viciously defeating Night Thrasher, easily tearing through his reinforced armor. Ultimately, the Hellions lost by attrition, though nobody defeated Catseye in turn.
Soon after, Emma threw another party which the Hellions as well as the X-Men Gold team attended. It was there that Trevor Fitzroy—a member of the villainous group known as the Upstarts—crashed the party with the goal of killing Emma in order to gain points within the group. Some of the Hellions died in the initial firefight. The rest, including Catseye, were killed in order to fuel Fitzroy's teleportation portal.
Also in the Generation X #55-56, the Generation X members become trapped in an illusion by Adrienne Frost where each of them is a different Hellions member except for Jetstream. The afflicted heroes relive the Hellion's last day. Jubilee was Catseye.
Even in her human form, she retained some catlike physical features such as slitted pupils and a tail.
It was stated in earlier New Mutants stories that Catseye may in fact be a mutant cat with the power to assume human form, explaining why she found human speech difficult and appeared to be more "animalistic" in character.
