[X] Check on the others. Make sure that they're okay.
While you are a bit cross at Madoka for potentially putting all your friends in danger, you're more concerned with their current well being as opposed to talking to Madoka and making her end this charade.
Besides, Madoka will be glad that you checked in on everyone. A bit of moral high ground for you to start the inevitable conflict on.
So with a flick of your twintails, you phase into the realm of the metaphysical and rush along to where your friends are, following the connections they all have back to your original world. You hope everyone is doing well.
Everyone has turned into Monsters.
Except Sayaka and Kyouko, who became heroes.
You honestly don't know what you were expecting.
"Ohohohohoho~!" Mami laughs from atop her mountain of cake, her form nearly unrecognizable, as she's also made out of cake, "Do you two honestly think you can defeat me, the Pastry Queen?"
"Guh, she's too strong!" a red-colored Sentai-wannabe (Kyouko) curses as she jumps away from Mami's army of ravenous cake minions, "Blue Ranger, heads up!"
The blue Sentai-wannabe (Sayaka) dodges a blast of whipped cream, striking a dynamic pose (that looks a lot like a dab) while shouting, "Mami-san, please come to your senses! Just because nobody liked your cheesecake at the party doesn't mean you have to forsake your Humanity!"
Mami pauses, tears of cream flowing down her cheeks as she bites back, "It was Hokkaido cream cheesecake! It was my masterpiece! Cat Woman, attack!"
And of course "Cat Woman" is-
"Myrow!" Amy leaps onto the scene, a catgirl covered in fur (but with an uncovered face). She brandishes her claws at the pair, hissing, "Humyans are a scourge on societnya! I will turn all of you into kitties!"
Padding alongside her is Cherry, who is unchanged.
That cat is just... weird. But cute.
"Then you leave us no choice!" Kyouko declares, pointing dramatically to Sayaka, "We have to use our ultimate attack!"
"It tears at my heart, but we must!" Sayaka lands next to her, grasping both her hands as they do another awkward pose, forming a diamond shape. Energy gathers between them.
"Super..." Sayaka intones dramatically.
"Ultra..." Kyouko continues.
.....
You... don't know why you expected anything else.
[] Break out the popcorn. Watch until they're finished (but intervene if someone is about to die).
[] Step in and end this as a Goddess. You won't allow your friends to make fools of themselves.
[] Step in... as Fantastic <3 Wargirl Tamura-chan! You'll defeat them both for your own nefarious schemes~. Also you'll end all your sentences with "Homu".
