Petropolis 13

Petropolis 13 (ペトロポリス13) is an action-adventure video game developed and published by Namco. In addition to the basic action-styled gameplay, it introduces the use of new special attacks, borrowed from the fighting spinoffs. Plus, there is a "Free Mode' where players can play as other characters not exclusive to the story mode and revisit stages.

Story
One year after the battle against Bloom Insectos, Dr. Shinichiro has built a resort in an island called the Hispark Island. He invites some of the heroes as his first customers, but it ends up going on the wrong direction. An alien names Mind assumes control over the resort and rebuilds it as a way to enslave the inhabitants of Hispark Island, the Faeries, planning to use their energy to revive the Deus Ex, of which Mind was a part, and the only survivor due to not being connected to the Cerebral Community. He then unleashes a mysterious entity named Haze to shroud all of the magical Faeries, including the Faerie Queen, with his dark energy. Now it is up Thunder and his friends, including Soul, who wandered onto the island after sensing the presence of the Deus Ex, to free the Faeries and stop Mind.

Non-Playable

 * Dr. Shinichiro: The goat beastman who created the Hispark Islands resort for the heroes.
 * Faeries: Magical beings that reside in the Hispark Islands. They have been captured by Mind after his arrival on the islands, but after the heroes free them, they offer their strength.
 * Mind: The main antagonist of the game. The sole survivor of the Deus Ex race after their leader was eradicated by Soul, he seeks revenge by settling on the Hispark Islands resort created by Dr. Shinichiro, hoping to construct another Tartarus tower on its ashes. To do this he enslaves the Faeries and their Queen using the power of Haze. At some point, the heroes encounter Mind as he uses the power he drains from a thousand Faeries to assume a monster form, all while unleashing the corrupted Faerie Queen on the heroes. Thunder and his friends stop the Faerie Queen while Soul transforms and destroy Mind. After all that is done, Dr. Shinichiro finally restores his amusement park to normal, the Faeries are freed and the heroes are finally able to enjoy their vacation.
