What would be Joker's calling card message to your favorite DB combatant?

Examples:

"Megatron, you became the thing you hated most when you grew the heart of a tyrant."

"(Dr. Ivo Robotnik/Dr. Albert Wily), the thirst for power has corrupted your heart. You're scheduled for a heart transplant surgery." (The Phantom Thieves' job was stealing heart treasures to change it.)
