Ok, so does anyone remember Friendship is Manly? If yes, then that's where I heard the Pillar Men theme for the first time; in that damn silly MLP animation XD — however, after watching JoJo properly, I realised that holy shit, Kars and Adagio Dazzle are so damn similar. Joseph and Twilight, on the other hand…
I dunno, just wanted to sketch this silly crossover for a while, especially after finishing Battle Tendency; it's always fun to see how different franchises would interact with each other :D

Adagio Dazzle and Twilight Sparkle belong to Hasbro
Kars and Joseph Joestar belong to Hirohiko Araki

DISCLAIMER: I don't ship Adagio Dazzle and Kars! I personally think they would be partners in crime at max. I just wanted to make Joseph react in a silly way.
