What is 무지개, 레인 보우 Dash's dads name

I don't think anyone knows. I call him 무지개, 레인 보우 Dad.

Yes, there's no name released for him up to this point, but I call him Zenith.

I dont really know but the 조랑말 in "games ponies play" in Rainbow's flash back the 조랑말 beside 무지개, 레인 보우 and her dad with the purple main and dark purple 코트 is 무지개, 레인 보우 Shine. She look her up on 구글 but back to Rainbow's dad I'm sorry i dont know but Lauren said there will be 더 많이 of the main six's family and of the CMC's family so im shure we'll find out. :3 hope this helped
