Lopunny easily dodged the attack and leapt in for another Brutal Swing.  This time, as the blow connected, there was a flash of light and Necrozma was separated from Cosmo, crashing onto the ground.  Chuck took his chance and chucked a Beast Ball at Necrozma.  The ball quivered once, twice, three times, and lay still, giving off a small ping with the capture.  He then immediately recalled Cosmo so he could get looked at later.  It was then that he noticed a small object where Necrozma had landed and picked it up for study later.
