It wasn't going to be an official battle, but Axew would've got a lot of confidence in it, which ended with Axew learning giga impact.
Her garchomp has max IVs, it was most likely bred using a complex eugenics program that discarded hundreds of imperfect Gibles. Or Cynthia somehow got Dialga to give her the seed times for the RNG for a perfect gible.
