One of the best parts of Assassin's Creed Odyssey is its mercenary system. Wandering the world is a rogue's gallery of hitmen and hitwomen for hire and they've all been bought up by your enemies. You can barely take a step in Greece without being jumped by someone looking to make a quick buck. The next mercenary to be added to Odyssey is a throwback to an earlier tough guy, he's the half-brother of Testikles.
