The deal is this: like the title says, a Riza Hawkeye (Fullmetal Alchemist) character exist, but the author lost the original files 4 years ago.
It can be seen in this video:

And in this one:

Both of this autors have lost their original files, but one claims that they have created a Roy Mustang and a Lust character.
The ony one that comes to my mind that has created a Roy Mustang char. is Tetsuo9999 . There is a big chance that the poster of the video isnt him (coudnt find any relation with him) but if it is him, chances are that the character is up somewhere.

If it exist, where it can be found?
