What about Mukuro? The other child of chaos deserves love too. The Clown Prince of Chaos and the Ultimate Soldier. Ultimate Team. I don't know about you, but if I were The Joker, and I was going to reach out to one of my daughters, it would be Mukuro. She is a highly skilled marksman and combatant, feels no remorse whatsoever for the lives she prematurely ends, but more than anything else, she is family-bound. Mukuro is dependent on her family. She desires her sister's and possibly her father's praise and affection and is willing to do damn near anything to get it. Murder, theft, acts of terrorism... She would follow Joker to the end of the Earth for a pat on the head.

Wouldn't that also make him Mukuro's father

Wait Junko is the Joker's daughter, that, THAT actually makes sense

ok I guess but I think it would have been funnier of the joker had a tear of joy he need to whip form his eye
