HIM vs. Bill Cipher: Demonic entities from popular cartoons, who are known for losing against children and making shady deals with every person they come across. Both have their comedic tendencies, but actually pose serious threats to the main protagonists of their respective series.

Also, I think Wander from WoY should represent Generosity.
