Wilbur soot. That famous criminal who was very dangerous, they said he was a completely normal person but since his country was stolen they say his mind disappeared and now he acts for the sake of acting, he literally lost his mind, he always uttered the same phrase before killing someone

"Look at my 9mm! This goes bang!"

After that the "bang" of the gun was heard. One of these days you ran into Wilbur in a lonely alley in the dead of night...
