Thea had undergone more than a year, nearly two years, of training, and her physical abilities had improved tremendously.
But that alone would never have let Thea defeat Deathstroke, who had been enhanced by the Mirakuru serum, much less give him a thorough beating.
However, Thea had learned more than just fighting techniques. She had also learned magic and the Cosmo Yinsen had tinkered with.
Learning magic gave Thea a wider range of offensive options in battle, making Deathstroke, who had never faced such powers before, extremely uncomfortable. Sometimes, he simply had no idea how to deal with those bizarre abilities.
Cosmo allowed Thea to use magic freely while also unleashing astonishing power when necessary. Especially moves like the Meteor Fist, which ordinary people could neither endure nor easily evade—even Deathstroke, enhanced by the serum, could not take more than a few punches.
If that had been all, Deathstroke would merely have been locked in a difficult battle. It would not have been easy for Thea to defeat him, and the final outcome might have been inconclusive.
But Yinsen had also given Thea a Pegasus Cloth. She had possessed it for over half a year and still had not figured out how to use it.
Yet the items Yinsen gave people generally had hidden effects, such as activating automatically in a crisis.
Just as Thea fell into a hard fight, the Pegasus Cloth sensed that its "owner" was in trouble. After all their contact over this period, Thea had already established some degree of connection with it. It simply had not responded before because her own power still needed to grow.
But trouble changed things. The Pegasus Cloth activated on its own and equipped itself on Thea, causing her Cosmo to surge severalfold as she unleashed the Pegasus Meteor Fist
