Like it says on the tin.
The twist?
Before Carol prepares to run through the entire MCU(heroes AND villains alike...) she reads too much Keijo and for some reason, her brain absorbs all the techniques to the point where she is able to perform them!
VACUUM BUTT CANNON! GATE OF BOOTYLON! METEOR HIP! GOD HIP IMPACT! And by crossing up her sheer speed and Gate of Bootylon, she can even use the combo attacks! Hell she can even amp her speed with W-Accel...
Can the MCU survive Keijo Master Captain Marvel?
*If you want to know what these techniques are, search Youtube yourself. You'll be laughing for hours.
