The Crystal is shown to amplify April's budding psychic powers, to the point where it can give her telekinesis. She has used this ability to direct her tessen in flight, and to repel enemies and objects directed at her and her allies.

When Donnie tried to study it, a strange spectral mass came out of the Crystal, bringing several pieces of equipment to life. Later it shown to bring Monoculus, Wingnut, Screwloose, and their gear from a comic book to life.

This crystal is not without flaws. During Bat in the Belfry, April was complaining about headaches and strange nightmares about outer space. However the most noteworthy drawback about the Aeon Crystal is its addictive properties. April became overly obsessed with this relic, quickly snapping at the Turtles, and straight out calling it hers. Even Wingnut and Screwloose weren't immune to its properties, as Wingnut stated the crystal was the source of power and life itself.


The Crystal itself looks like the tip of a spear or arrow, welled out in the middle of the diamond-shaped head. On the opposite side of where it connects to the necklace, it has a small hollowed-out circle.
