Not too much, but I can tell you that their wings are just as vulnerable as ours, although they're bigger and can be used for flight.

[It's something she's made great use of when fighting against them in the Battle Dome training simulations.]

Apparently all attempts at reasoning with them have failed and they're determined to kill every last person in Luceti and enclosures just like ours. I can confirm the 'wanting to kill us' part personally. Dad and I didn't even DO anything to them and they tried to kill us. They wouldn't even explain themselves.
