Alright, so i realize i'm coming in really late, but I've been distracted recently and only just found out about this. So, here's my idea:

Edit: this is now my Final Submission
Aurumoth, the Divine Moth Pokemon

Black: They have a tendency to reside in remote places, only seeking humans who are said to be powerful to test their strength. It gives its blessing to the victors and curses the losers.

White: Because of its softness, most Aurumoth wings are actually not pure gold. However, its antlers can act as dowsing rods, detecting anything valuable a human it deems worthy could ask for.

Black 2/White 2: Legends revere Aurumoth as the servants of Arceus, who test trainers in battle to see if they are worthy of partnership. It is said that powerful kings actually had Aurumoth guardians.

So, thats pretty much it. I will finalize this in a little while if no one has any last minute critique. Sorry about being so late.
