From what I've gathered, the various items of the Miraculous world can grant limited super powers, and one specific one-time use ability to the wielders. The old Chinese guardian actively chose the current Ladybug and Black Cat... but the villain Hawk Moth's powers seem to work somewhat differently.
- He doesn't lose his power after transforming a person
- His main weapon, the can sword, shows no extra abilities
- His affects vary from person to person
- He has a telepathic link with his Akumatized individuals
- He has a stronger mental connection/control over his Kwamii
Thing is, in the episodes I've seen, it's never explained exactly how he managed to get the Kwamii Nuruu to begin with. I'm guessing he went on some quest to find a supernatural solution after his wife passed, considering how obsessed he seems with her portrait.That may have lead him to the legend of the Miraculous, but if they were in the care of the Old Master, it's unclear how he might have managed to lay hands on the Moth pin.
Is there any backstory on this?
