1. Allen Walker, because he can be hilarious especially when his past with Cross and debts.

2. Wisely ( don't know if he has a last name), even though he's a new character from D. Gray-Man hollow I still like him cause he's hilarious I mean (SPOILER ALERT) when the earl and Sheryl ( I think it was Sheryl ) , or pretty much everyone in the room, was surprised over that kanda asked who's that when they showed him that Alma was alive they were like Wisely why'd he say that so whenever he's involved it's funny.

3. Marian Cross, because it's so hilarious when he makes others pay his debts and he's always on the run.

4. Tyki Mikk, because........ Just because!  (couldn't think of a reason he's just number 4 because I like his character )

5. Kanda Yuu, because whenever he picks a fight it's hilarious not to mention he's funny when interacting with people ( especially general Tierdoll, I think that's how you spell it ) .

6. Lavi, because he's Lavi.

7. Timcanpy, because he's cute and funny.

8. Jasdevi ( Devito/Devit and Jasdero ) , because the their grudge against Cross was hilarious.

9. For/Fou, because she's a kind and funny character.

10. Komui Lee, because of his hilarious sis-con and his hilarious komurins!

That's all and don't judge me I like the comedy in this show and the seriousness it's a great combination and I know I choose most/all characters because they're funny or themselves but that's how I see it.
