Digimon Pendulum

The Digimon Pendulum were released in 1998. There were five regular versions released. Following the release of each version wa sa .5 release that replaced certain characters available with a different variety. Pendulum Zero was released a bit later and featured the 'main' Digimon characters from the Digimon animated series, Digimon Adventure. The Digimon Pendulum came in a slightly altered design from the original, but functioned in similar fashion.

Gameplay
The Digimon Pendulum worked almost exactly like the originals, but there were a few new features. One of the major features, and where it gets it's name, is the new pendulum inside of the unit. This feature was used during training and battle. You would just shake the pet back and forth to "power up" the Digimon. Another new major feature was the ability to jogres or DNA Digivolve. Jogressing could be done by going to the Battle Icon and selecting jogres, you then link together two digimon will full DP and they will combine thrir data to become a new digimon of a higher level (Two Champions become an Ultimate, Two Ultimates become a Mega). Not all Digimon are compatable with eachother for jogressing. This was also the first time that the Mega level appeared.
