Lawrence "Larry" 3000 (voiced by Mark Hamill) Originally designed as a diplomat, Larry was put into Time Squad service when the world's nations all joined together in the year one million, an event which turned out to be the worst thing to ever happen to him, second only to being saddled in Tuddrussel's unit. He is the only one capable of operating the time-traveling technology and most of the technology aboard the space station. Larry is also often shown to be grumpy and pessimistic, but it is not uncommon for him to show enthusiasm and joy. He is an expert chef, although Otto is the only one who seems to appreciate his rare delicacies, as Tuddrussel just wants a cheese burger. He is also skilled at needlepoint, computers, cooking, and household chores, though he gets little to no appreciation from Tuddrussel. Although Larry expresses deep disdain for Tuddrussel, deep down he does value his friendship.
