For this chapter, is the character that I've been wanting to do for a while... Vexen!
-Vexen-
"You haven't got the heart."
1. Call him old!
2. Lock in a room with Larxene.
3. When you let them out, they will be both REALLY mad. Laugh and tell Vexen that he's a mad scientist, now.
4. Whenever he says that he's going to work on a new experiment, instantly tell him that it's going to fail.
5. Tell him that his hairstyle looks girlish.
6. Call him a coward, hiding behind his sheild, like that.
7.Whenever he starts talking, say VERY loudly: "Really! Do you have to make all those weird faces?!"
8. If he says that he doesn't know what your talking about, say, "Like this!" and immitate him, exagerating it as much as possible.
9. When you want to get his attension, either tug on the long hair in front of his ears, or knock on his sheild.
10. If and when he gets mad about this, tell him, "Aw... don't be so cold!"
11. Ignore him all day.
