Hey, guys. While I was writing a fanfic, I was only thinking of a name of a Changeling who was a biological daughter of Queen Chrysalis, but was raised by ponies, and made her pure good. Any ideas?

Elytra, perhaps? Or maybe Iridescence?

do you need a name given by Chrissy, or a name given to her by ponies?

As a rule of thumb, you can check wikipedia for articles relating to your theme. There's often some animal names that work well in general. Based on that, one name that stood out to me was Melecta. It's a type of bee, and one of the species in it is a kleptoparasite, which is nice and ominous. 'Mel' is a simple nickname you can use, and even if people don't know exactly where it's from, most readers with a bit of a language noggin will get the honey reference.

Nice name, only if she was raised by Chrysalis.
