Matsumoto
Matsumoto is an AI sent back from a century in the future with a pretty heavy mission: prevent an all-out war between artificial and human intelligence. To accomplish this, it teams up with Vivy, and together they're working to destroy other AIs—basically trying to stop the conflict before it starts.
What's interesting about Matsumoto is that it doesn't really come across like your typical AI. It's talkative, prone to overconfidence, and has way more personality than you'd expect. Fans often note that it breaks the mold of the cold, logical robot archetype. It's chatty, sometimes cocky, and reads more human than machine—which, depending on the situation, either helps or gets in the way of its mission.
