By the time of post-Stars, each of the girls could possibly wipe the Floor with Beryl on their own.
And just in case they really gave her a shared group Beatdown, it might go something like this:
Well, this is for daring to use Lightning against me
! *shoves up said Lightning up her A**e*
is for BBQing me! *forms Icicle and rams it right behind*
This one is for burying me
in Ice! *roasts her with a giant Fireball*
This is for… ahem… (silly face) well, for attacking me
first! *whips her with the Love Me Chain*
is for killing the other four and forcing me to fight the final Battle alone! *takes Aim with the whatver-the-Rod-in-Stars-was-called-again and starts to strike it down on her*
Beryl (Raises hand, Sweatdrop): Ladies, hold it! Chillax! That was an Eternity ago and it wasn't me who did that, remember? The DD Girls did!
All Senshi: But they're not here, and you greenlightened them, didn't you? *Evil Eyes, Mean Grins*
Beryl (In her thoughts, more & bigger Sweatdrops): Uh-oh, I think I'm screwed!
