Sanrio Timenet: Mirai Hen

Sanrio Timenet (Japanese: サンリオタイムネット) is a monster-battling game developed by TOSE for the Game Boy Color, which is also compatible with the Game Boy.

It was released in two editions, named Sanrio Timenet: Kako Hen (Japanese: 過去編) and Sanrio Timenet: Mirai Hen (Japanese: 未来編); literally Sanrio Timenet: Past and Present Edition.

There are small differences between the versions, including different available monsters and each version being originally set in its respective time periods (past for Kako-Hen or future for Mirai-Hen).

Players build up a team of creatures (“monsters”), often by catching them using items known as Get Cards (or later in the story, a Digital Camera) and use them to battle against other creatures.

The games support the Game Boy Game Link Cable; which can be used to battle with other players and exchange information. Pictures of monsters and Sanrio characters met in the game can be printed using the Game Boy Printer.
