Ridley(Metroid) vs Ryuko Matoi(Kill la Kill)

Who will win the battle & what is going to happen as Ridley is about to eat Ryuko alive?

Condition: Ryuko has all the abilities she can use while Ridley can only transform to Meta/Omega Ridley when necessary.

You know I watched me some Kill la Kill...

I have no idea how to classify anything from that anime.

Condition: Ryuko has all the abilities she can use while Ridley can only transform to Meta/Omega Ridley when necessary.

ALL the abilities she can use? That includes Senketsu-Kisaragi in which her regeneration makes her basically impossible to kill, at least for someone of Ridley's standards. She's also Massively Hypersonic

@strictlyanime: So let Ridley from Metroid Prime transform into Omega Ridley to keep up with her since Omega Ridley is also Massively Hypersonic and what i mean is that Ridley can transform to Omega Ridley if Ryuko is at full power, otherwise Ryuko can also be only at her full power when necessary.
