Johnny the homocidal Maniac: who is best paired with an apprentic?

Kay, i am an advid FanFiction writer on Fanfiction.net, i can make polls there sure, but no one takes them... so i give up, i'll make one here.
I have a serise of FFs that include my favorite character with an Apprentic, so far I've got Willard, but i've got ideas, but i SERIOUSLY need to make a JTHM since i've got a long LONG term writers block on my Family Reunion.... so... which one is best fit with an apprentic, any ideas for it message me!
