Is it true that Vince McMahon wanted Emmalina to be the modern day version of Sable or Debra, and he felt she wasn't able to pull it off?

LMAO yeah its likely - even when she was debuting the "bubbles/ emmalution" charachter back on nxt and even in on raw for a short time with santino, everyone who actually knew her was suprised because of apparently how much of a square she was said to be outside the ring and in general lol - she's from the Indies in Melbourne, Australia, never saw any of her work here to be honest, because i got into "the scene" around the same time she was signed and left for the US to nxt , however watching her nxt/wwe work she's good, but a tiny bit overrated, would be great to see other great aussie female wrestlers like Evie (well technically she's from New Zealand but wrestles here all the time) and the best aussie female wrestler iv'e seen - Demi Bennet - still too young for a wwe contract i'm pretty sure though, must be 18 or 19 now lol

KC cassidy aka "peyton royce" on the other hand, seen tons of her work, though nothing really special or memorable to be honest, so i was just as surprised as everyone else when she just randomly showed up on nxt one day lol

Maybe

No

Yes

Emma is hot
