Project GeeKeR (1996)

A strange monster is wreaking havoc on the city of Neo-Denaire. Becky and Noah are shocked to discover the the ""monster"" is actually a sleep-walking GeeKeR. Noah learns the cause of GeeKeR's Jekyll-and-Hyde transformations; a signal beamed at GeeKeR from an orbiting satellite. But GeeKeR is forced to stay awake to avoid becoming a monster, and his sleep deprivation-induced hallucinations cause no end of trouble for our trio.
