I had a random idea for a DB, since Wiz and Boomstick declared Pinkie Pie could potentially do about anything with how she can break the laws of physics so often.
PINKIE PIE VS. SEGATA SANSHIRO
and if I made this battle, I promise I won't end it with friendship. Not sure if I'd want to kill off a beloved pony, but we'll find out one day.
Also, I thought the Pinkie Pie vs. Deadpool was pretty funny. It could've been better, and it would've been great to see it be, y'know, an actual DEATH Battle, but it was obviously just supposed to be a joke battle.
