Gengo

Gengo, alongside other fellow shinobi from Kirigakure at the time, allied with Zabuza Momochi in rebellion against the Fourth Mizukage: Yagura Karatachi, and his destructive methods of ruling over the village. Due to a traitor in their group, however, Zabuza and the rest of his followers, including Gengo, were forced to flee the village forever. After the incident, Zabuza and most of his other followers began collecting capital as mercenaries, never letting go of their dream to go back to their motherland. When Zabuza began accepting work from corrupt people, however, Gengo — alongside many others — left and became disillusioned about such goals. Upon leaving Zabuza, Gengo and his comrades made their way to the Land of Silence and took over the nation. Following Zabuza's ideology, however, Gengo had all his comrades killed and their bodies hidden away in Fushū Castle. During his regime, he developed a speech-induced genjutsu to further his goal of controlling others to do his bidding. During the Fourth Shinobi World War, Gengo grabbed the opportunity to put his new abilities and plan into action; rallying many young shinobi who felt displaced following the war and putting them under his control to form the "Enlightened Ones". This continued for two years after the war and he slowly built up his power, having his brainwashed minions take missions from the Shinobi Union at cheaper rates in hopes of building a vast amount of capital for his goals. His followers had even gone beyond the Land of Silence and infiltrate each of the Five Great Shinobi Countries without raising suspicion; willing to stir an incident among their citizens at Gengo's command and putting the Shinobi Union in jeopardy of terrorism.
