Kamen Rider is the Villain in Pretty Cure

"What the hell are you going to do?"
"I'm looking for Pretty Cure stickers."
"You misunderstood me buddy. I'm talking about you appearing as a mysterious third party, being both a good person and a bad person. What is the purpose of constantly collecting darkness, where are you going, and who are you fighting for?"
"In order to get some pretty girls as wives."
