Beast Rizer 11

Petropolis 12 (ペトロポリス12)  is a video game released in late 2008, launched for the Xbox 360, Nintendo Wii, and PlayStation 3. The game sees Thunder hindered by a new "Gargyote" form at night, and travels to both return to his normal form and stop Whisker and the organization GHOUL from breaking up the world.

Story
The story starts as Whisker and Dr. Von Gerbil's chimera station is in orbit around Earth, and Thunder goes to stop him. Using one of his chimeras, Whisker is eventually able to capture Thunder, only to have the robot destroyed as he becomes a Super Chimera. With his creation destroyed, Whisker flees with Thunder pursuing. Meanwhile, Dr. Von Gerbil lures the two into a chamber which rips the eight Sacred Orbs from Thunder and harnesses their power to break the world apart, causing a monster to awaken from the center of the planet.

Dr. Von Gerbil's machine, however, caused some unintended side effects: The Sacred Orbs end up losing their power, and they turn Thunder into a Gargyote (gargoyle+coyote). Thunder then falls toward the shattered planet, and meets a small creature who has lost his memory. Feeling remorse that he may have caused the creature's amnesia, Thunder decides that he must find someone who knows his new friend, and put the planet back together with the help of Quill, Pixy, Yoshino, Mix and a philanthropist named Léone. In order to fix the planet, Thunder must find the Sanctuaries of Light to reawaken the Sacred Orbs' positive energy and with their power, they will restore a piece of the planet back to surface. He must also try and stop the organization GHOUL (Gathering of Horrific Overlords for their Ultimate Legacy) from preventing that goal.
