I really regret doing this to Vexen...

Vexen

Yell KABOOM! Every time he walks by, and ask him how being blown up feels

~luvablenerd~

Tease him about being beaten by Axel

~Zacheria~

Walk up to him and tug on a peice of his hari asking, "Are those extensions?"

~DestinysDarkestAngel~

Whenever he walks by you, yell "YOUR EXPERIMENTS SUCK!" then flee for your life

~Ryxlet~

Call him Grandpa
Use his shield as a sled
Destroy his lab (Axel's help is optional)

xRockxMetalxBbyx9

When you walk by him, shout, "OMG, THE CASTLE'S ON FIRE!"

~Khfangirl681213 ~

Ask him what type of research he does. When he tells you then say "Oh I thought your research was just like the Pervy Sage's from Naruto."

~Edward-Elrics-Girl~

Ask why he's the first one to die. When he cries, laugh.

~AitheHeartlessGirl~

Wow...You ppl must really hate him...*goes into depression* Next is...*checks list even though I don't need to*....Lexaeus.........
