Twin Signal

Twin Signal is a manga series written by Sachi Oshimizu. It was later animated into a 3 episode anime OVA series in 1996. Both the manga and the OVA have been licensed by Media Blasters for distribution in the USA.
It follows the story of a humanoid created by a robotics expert named Dr. Otoi for his grandson, Nobuhiko. But in the process of writing and applying the programming, an unfortunate mishap took place when Nobuhiko sneezed. Now, whenever Nobuhiko sneezes, the humanoid transforms from a temperamental adult robot into a chocolate-loving baby version of himself.
Despite this, the days spent with the Otoi family are usually fun. Animals, people, and robots all live in harmony.
One day, Signal is attacked by Pulse, a robot created by Dr. Otoi some time ago as Signal's prototype. Pulse is incredibly nearsighted, but makes up for what he lacks in vision with firepower. Dr. Otoi's mysterious rival has packed him to the brim with amazing weaponry, with the intent of stealing the Doctor's most recent technology.
