Petropolis Beast Fighters

Petropolis Beast Fighters (ペトロポリスビーストファイターズ) is a 2.5D fighting game developed by Burst Arts and published by Multisoft for the Arcades, PlayStation 4, PlayStation Vita, Nintendo 3DS, and Nintendo Wii U. Compared to its predecessor Petropolis Fighters X, this game reverts back to a simple roster and bases its gameplay on Power Battlers Megamix. It was released in June 2014 in Japan and September 2014 overseas.

Plot
In the events of Petro+, Thunder and the Garage Kids attempted to defeat World Red, the leader of the Mixed Marshals. Before World Red could even use the Infinity Diamond to unleash a powerful world-ending attack, Thunder transformed into a chimera and managed to break the Infinity Diamond, thus defeating the Mixed Marshals.

Fast-forward to 18 years, Subaru Whisker and Dr. Von Gerbil were mining for a strange gem with incredible power, believing there is another that exists. They then find fragments of the Infinity Diamond, which were buried underground after the final battle against the Mixed Marshals ,and managed to reform it in order to begin their latest creation. Eventually, their project, titled Mugen, was complete and attempted to threaten the lives of the beastmen of Petro Islands. It is up to Thunder and his friends to stop this mysterious creature from terrorizing the world the same way the late Mixed Marshals did. This also caught the attention of Planet Gramm, where Tri and his brother/rival Tan put aside their differences and gather some fighters from Tan's home, the 2nd Dimension.
