[Merskelly Metalien]

No one asked me, but,

Mine is Merskelly Metalien, because Mermaid+Skeleton and Metal+Alien..

also it's neatly coincidental that my username's shortened abbreviation is M.M. which was my nickname in high school for a completely different reason.
I was nicknamed M.M. because of my ridiculous love of pizza, and a friend gave me this nickname because I had an identical haircut to C.C. from Code Geass,

(Not my art)

and I was just as odd and sneaky as the character. So she took my name's first letter, M, and just, well, M.M. :/ I kept the nickname ever since..I even put it down for high scores in video games and sometimes usernames across other platforms.
