I can't belive this

ok check it out,

Here's my two cents, I like the NOANGEL idea but i wanted to put down some of my own I can't remember if it you said it had to be less than 7 or just at 7. So I'm sorry if some of these don't work

1. BADM0N (BAD MAN, or BAD DEAMON)
2. S1NN3R (Sinner)
3. B3LZBUB (Beelzebub)
4. MANLIVE (Mirrored :EVIL MAN)

hope these help.
