Sanrio Timenet: Kako-Hen and Mirai-Hen



Sanrio Timenet: Kako-Hen and Mirai-Hen (Japanese: サンリオタイムネット過去編／未来編), meaning Sanrio Timenet: Past and Future Editions are Game Boy monster battling games featuring both licensed Sanrio characters and original characters attributed to Timenet. The games were developed by Imagineer (likely the Timenet team) and a group of various other companies.

The games received a spiritual successor called Space-Net: Cosmo Red and Blue.

Story
Due to the work of somebody, time was divided into the past and present. As requested by the Toki no Roujin, the player must enter the world of Timenet to recover the lost fragments of time to go to Mars Basis and solve the mystery. On the way, a mysterious girl screams for help.

Gameplay
The hero (male or female) as asked by the Toki no Roujin, travels the world of Sanrio Timenet collecting and raising monsters raised by Sanrio characters, and can also battle a rival of the opposite gender. The hero is given a starter monster (bodyguard) by the Toki no Roujin. When the player defeats a trainer, they are given the choice of recruiting it, but wild monsters can also be captured with Get Cards or the later Digital Camera key item which can be used infinitely.

Eventually, also requiring collecting 161 monsters (which do not have to be unique) and gathering all fragments of time, the player can travel to Mars Basis to defeat the powerful Monster Zakki and White Zakkī.
