Corrin, for obvious reasons, is my #1, but recently I had this dream I got jerked off by a brainwashed Alear...

Azura maybe

azura isn't an avatar

the fire emblem avatars are:
-kris (new mystery of the emblem)
-robin (awakening)
-corrin (fates)
-byleth (three houses)
-shez (warriors three hopes)
-alear (engage)
-kiran (heroes)
