Madelyne Pryor was a clone of Jean Grey. She was first affiliated with the X-men, but became a demonic-powered supervillain named the Goblin Queen.

Since Madelyne was cloned from Jean Grey's DNA, she was essentially another version of Jean, and possessed Jean's telekinetic and telepathic abilities. She also developed powers that Jean never possessed. Madelyne was able to teleport over long distances by psychokinetically shunting herself in and out of the astral plane (and was shown to be able to carry additional weight, such as another person, when she teleported, but her limits were never fully tested). Madelyne also discovered that she was able to siphon the psychic energies from other psionic mutants. She could then use the stolen psychic energy to boost her own powers or channel the energy into someone else (usually Nate Grey, and Cable) to temporarily increase their psionic abilities.

Madelyne uses her telepathy to read her opponents minds and her teleporting powers to DODGE her opponents, and she also uses her telekinetic powers to CATCH the ball.
