Kuklo, from the Attack on Titan: Before the Fall of Wall Maria, is the saviour of humanity. If you don't know the AoT:BFWM is set 60-70 years before the main story with Eren and the others. This was back when the walls had only existed for about 30-40 years. They didn't have Vertical Maneuver Gear, just normal swords and muskets as well as the cannons. Kuklo found an extremely early version of the VMG, it just had one handle with a wire attached that shot a single weak hook with no replaceable swords or scabbards. It could only move up and down and had two large gas canisters. One on each side of the user's waist. They considered it crap but Kuklo said it could possibly be used to reach the Titan's weak spot which was the neck. (They were still unsure of how to kill a Titan since only one was ever killed and it was by accident). They tested it out and eventually developed into the VMG we know today.
