Yu-Gi-Oh! VRAINS episode 103: "Journey to the End"
SOLtiS are upcoming androids by SOL Technologies to help assist humans worldwide. However, before they were released to the public, two of them were reprogrammed by Ai and Roboppy to serve as avatars for them in the real world. This came in handy for tracking down and incapacitating members of SOL Technologies like Queen and Akira Zaizen.
