Hondo somehow survived all his encounters with the Jedi and the Separatists. After Order 66, the only group of people that were ordered to be executed were the Jedi. If you weren’t a Jedi at that time, no one was coming to kill you. So, Hondo lived through the Jedi Purge by continuing what he did as always. However, the Empire disbanded its Ohnaka Gang as they heavily disapproved of piracy in the universe. After that, he became a solo pirate during the Galactic Civil War.
