S.I.R. (short for Simulated Intelligence Robotics) was a robot character that hosted the pre-show of the now-defunct Magic Kingdom attraction ExtraTERRORestrial Alien Encounter.

He proceeds to demonstrate X-S Tech's "practically painless" teleportation technology using a cute little alien named Skippy, whose charred and disoriented appearance after being teleported a short distance across the room suggests that the technology is flawed. While teleporting Skippy back across the room, S.I.R. pauses the process, demonstrating how the technology can be used to suspend subjects in teleportation indefinitely, a feature that he absolutely loves.
