Mafia 92. Void Lord.

The Manticore is a fictional creature – a monster with the body of a red lion, the head of a human, and the tail of a scorpion.

In “Heroes of Might and Magic III” and “Might and Magic 7”, the Manticore looked like a lion with a scorpion tail and wings; in “Heroes of Might and Magic V”, a human face was added to the image.

Heroes of Might and Magic V (wiki):
release date in the USA - May 24, 2006
release date of the expansion pack in Russia - May 21 2009

and now:
Mortulus's date of birth - May 21, 1989
date of registration on the forum - May 24 2009

for now, this is the best I could find. I'll look for more later. If nothing better is found, execute Mortulus.
