Tattoo symbol with 3 interlocking circles with another circle in the middle.

The biohazard symbol was created to identify hazardous substances back in the 60's but is now part of popular culture. As a tattoo it was popularized by the band Biohazard.

An incel who uses children's video games to chat up underage girls to convince them to send pictures of them so he can show fellow workmates pictures of them under the guise that he's some kind of ladies man. Egotistical and psychopathic, they are very quick to claim to be the victim to cover their nefarious practices.
Did you hear about that guy who got added to the sex offender register for show pictures of young girls to his workmates?
Yeah he's a bit of a Biohazardous King!

The maddened grandchild of Albert Einstein. A terrorist and main player in WWII. Nobody knows his first name, as he only goes by the name of professor Biohazard. It is believed that in 1911 he created a bomb so powerful that even he couldn't comprehend the abomination he had created. In the year 1917 it exploded, in an event know as Halifax. After this he went missing and nobody has heard from him to this day.
Some people say he's still alive, living on the chemicals he creates.

Others say he took on the role of Führer of Germany in the year 1934 and died from drug overdose in 1945.
Others say he's still active in terrorism, only under the name of Osama Bin Laden.

None of these we can be sure of, all we know is that Professor Biohazard has, and possibly still does cause extreme chaos across the world.
