Undead Armageddongee

When Armageddongee is killed, he transforms into Undead Armageddongee. In this form he can't die again due to Undead Immortality. It is likely that you would have to revert Undead Armageddongee back to normal via Life Manipulation before you can kill him again, but if he dies again, Armageddongee returns to this form. AAAAAAH PARADOXX!!! (He in a certain amount of time returns normal Armageddongee, though, possibly regeneration).
