Screw canon, screw legal issues, screw Hasbro in general. Rainbow Dash's mother needs to be Firefly. I think Faust is owed that much, at least.
I just read the MLP wiki page and they have his name listed as Rainbow Blitz. http://mlp.wikia.com/wiki/List_of_ponies/Pegasus_ponies I agree.
I still want to know if the pegasus mare looking at filly Rainbow Dash is her mom or just some random unnamed background pony?
Well, she doesn't look remotely like her, so I doubt it. The dad's shade of purple clashes with the rainbow mane in my opinion. Just seems like a weird combination.
Isn't that Rainbowshine? The name seems quite fitting, and judging from the Cake twins and their mom, family resemblance is purely optional. Still, I doubt it.
Well you were right at first. Then they changed it to Bifrost and now this. I wish they would make up their damn minds!!!
