5. CLYDE BARROW (1910-1934)

Calling Card: Clyde and his wife Bonnie were known to be unpredictable and vicious.
Casualties: At least 13 people were killed, with nine of them being cops.
Complex Says: We only have Clyde’s name here, but, really, it’s a package deal. Bonnie and Clyde are the most infamous criminal couple of all time. During their three-year killing spree, the couple got OJ Simpson kinds of coverage for their various robberies and killings.

And let’s not get it twisted: These two weren’t really bank robbers. They were like psychopaths who robbed banks. Their gangsta was forever sealed with the Scarface-like deaths, when police finally caught up to the two and pumped more than 50 slugs into them.
