Villainous Kamen Rider in Pretty Cure

“What exactly are you planning to do?”
“I want to join forces with the Pretty Cure girls.”
“You’ve misunderstood me, partner. I’m referring to your enigmatic presence, switching between being a hero and a villain, constantly gathering darkness. What is your true purpose? Where are you ultimately headed? Who are you fighting for?”
“I’m fighting to win the hearts of a few Pretty Cure girls and make them my wives.”
