Plot
Three years have passed since the events of Petropolis 10, and peace began to settle on the Petro Islands. Bolt is beginning to learn more about his best friend's new morphman companions. Julie is doing more research on some of the morphmen Thunder found for her and learn that they can not only morph into different objects, but also into different forms. Bolt wonders if Thunder's morphmen can also undergo such a process. Julie attempts on making Yolk and Blur transform, but to no avail.

Later, the three and the others were invited by White Aether, a science group formed from the ashes of the Shadow Dragon Foundation, to their building. Soul, once seeing a message from one of their employees, believes he can find more answers from that organization, so he also joins his friends to visit the new facility. Little did they know that a mystical race of Z-Monsters is right behind them, planning to reawaken the mischief king of the Dark Ages.

Thunder's Side

 * Thunder Storminski: Remains the same from Petropolis 10, but later gains a new morphman, Rage.
 * Loren Sheldon: Relies on their psychic abilities from the Psion Rings to attack their foes.
 * Mindy Prayer: Using her mysterious Sacred Weapon, she cuts her foes in two.
 * Becky Spots: Attacks by jamming with her Venom Guitar.

Bolt's Side

 * Bolt Cinnastar: Has his abilities from Petropolis 10, but now has Glide and later an astral being named Serenity.
 * Milton Redder: Has his shapeshifting abilities from Petropolis 2, marking his first appearance since aforementioned game.
 * Gerald: The reformed G-65 can also morph certain parts of his body into weapons.
 * Angus Ward: Bolt's partner from Petropolis Pocket returns to assist. He is briefly playable before being injured by the attacks of the vicious Z-Monsters.

Soul's Side

 * Soul Squareshell: His abilities from Petropolis 9 have been nerfed to suit the style of the game. At some point he becomes possessed by Z-Monster mage Tile and attempts to kill the beastmen.

Antagonists

 * Tile: A miniature Z-Monster who arrived from a desolate island unknown to the beastmen. He and the other Z-Monsters plan on reviving the mischief king Moe by slaying many beastmen, believing that "the blood of those with life shall awaken that who creates disorder." His wish may have been fulfilled, but he was killed by Moe.
 * Karex: A dinosaur-like Z-Monster who is Tile's right-hand man. He had a part in slaying those who try to prevent the Z-Monsters' goal of awakening Moe. While on the Petro Islands, he froze Loren and their partners and invited Thunder, Bolt, and Soul to Tile's mansion to fight his other minions. Karex was defeated by Bolt while they were on the final room of the mansion.
 * Moe: A yellow-furred monster who is known as the "mischief king." Despite his jolly appearance, he is regarded as dangerous due to the fact that he turns anyone into crayon drawings. When Soul's violence accidentally awakens the beast, he sets off to transform everyone into drawings for his "collection" and will tear anyone who is "drawn bad."

Forms

 * Super Chimera Thunder (Thunder+Yolk)
 * Mega Chimera Thunder (Thunder+Yolk+Blur)
 * Hyper Chimera Thunder (Thunder+Yolk+Blur)
 * Super Dragon Soul (Soul+Daisy)
 * Z-Monster Soul (Soul+Tile's magic)
 * Mach Bolt (Bolt+Glide)
 * Celestial Bolt: The fusion of Bolt and the passing Serenity. When she was about to die, she pleaded Bolt to use her magic to defeat Moe. Celestial Bolt can fire magical bullets in addition to stronger "lightning quakes."
 * Thundersoul (Shocksoul in Japanese): The fusion of Thunder, Soul, and their morphmen. It was through the act of the morphmen fusing together and saving their respective owners from Mega Moe. Thundersoul is capable of performing "electric-ice attacks."
 * G-Red: The fusion of Milton and Gerald with the use of White Aether's Gattai Gloves. He resembling a life-sized robot with the features of his fusors. His mechanical body can also morph into weapons.
 * Jolly Moe (normal form)
 * Mega Moe: Moe's 2nd form after getting absorbed by his "evil" drawing, a muscular and menacing version of Moe.
 * Powerd Moe: Moe after absorbing the drawings of G-Red and Bolt (and Serenity, to an extent). With this form, he attempted to recreate everything to appeal to his chaotic nature. Thunder and Soul were able to escape to the Ancient Isles thanks to their morphmen, but they had to find a way to restore their world to normal. After the original Moe was separated from his corrupted self, Thunder and Soul fuse and finish the job, reverting the world back to normal.
