Google-kun is the twin brother of Google-tan. While both he and his sister don't get that much attention in the OS-tan world, his sister is more recognized then he is.
Google is very shy and prefers to be by himself with his pet puffball named Goo-chan. Because of his shyness, not much is known about his character. He dresses like his sister and tries to be like her in every way. Goo-chan occasionally likes to steal his glasses.
It is rumored that he is close friends with Mac OS 9-kun.
