Bosco Ntanganda
Known as Terminator Tango or The Terminator, Ntaganda was a Congolese warlord for hire. He took part in the rebellion that overthrew the Hutu-led Rwanda and then went North to Congo, where he committed numerous massacres and other serious human rights abuses.
Not only did he recruit child soldiers, he also encouraged them to rape and sexually assault women.
He later surrendered to the International Criminal Court, which charged him with 18 counts of war crimes and crimes against humanity allegedly committed by himself and his militia fighters.
He has denied all charges. His trial is still ongoing.
