The original series showed Arus as located in the Dinubian (or Diamond) Galaxy in the Far Universe while Earth was in the Near Universe (with the Vehicle Voltron defenses). Here, Arus and Earth are incorrectly claimed to be in the same, unnamed galaxy; its Azure, Cerulean, Crimson, and Coral Quadrants that were the Dinubian Galaxy's are referred to when effecting either planet.
Alfor died as a middle-aged man whose brown hair was clearly visible in the original series, yet whenever his ghost appears, his hair is silver.
