I don't want to copy anyone but a bat pony likening Luna this way seems logical only this is not really a bat pony but a disguise this will be reviled soon. (hint: that tooth and the color)
I choose the name Aku because why not, no it's nothing to do with samurai jack but Aku means:
The name Aku is of Babylonian origin. The meaning of Aku is "moon god". It is also of Finnish origin, where its meaning is "revered, exalted ". Aku is generally used as a boy's name.
Aku loves the night and the creatures who come out at night even the dangerous ones, his origins are unknown but he says he came from a faraway land. they met one day when Luna was out to diner when Aku came over just to talk and they became friends, he was somehow able to do magic despite not being a unicorn, he learned magic from his parents who were paraformers. He got along well with Celestia and discord though discord found something off about him at first, he met twilight and the others too and got along. sometimes his magic got a bit out of control when he got embarrassed or nervous but soon he got used to be around ponies so he expressed more of himself until one day… (will be reviled soon)
he is sweet a bit mysterious fun-loving self-conscious a bit awkward
but in all a lovable guy and a good friend
i know it's an OC but Sombra is dead so why not, I hope I did a good job because i rather do canon characters but there is no other choice IMAGE DETAILS
