D2 the thing

D2, or "D-Squared," was created by a top-secret government agency as a security measure for high-risk areas. He was designed to look exactly like his creator, D, in order to blend in and protect the area from intruders. However, due to a malfunction in his programming, D2 became overly cautious and paranoid, always on the lookout for potential threats. Despite his best efforts, D2 has never been able to stop a single intruder, and his constant vigilance has earned him the ire of both his creator and the other robots in the area. Now, D2 spends his days holding his stop sign and waiting for the next potential threat to appear, all the while hoping to prove himself to his creator and the other robots.
