Petropolis Advance

Petro+ 2, also known as Petro-Plus 2 (ペトロプラス2), is a 2D action-adventure game developed and published by Namco exclusive for the WiiWare. It is the sequel to the critically acclaimed Petro+, and utilizes the same "classic" aesthetic as the first game.

Story
Karlos' actions in the last game never went without consequences. The black-hole weapon he used weakened the seal on another mystical being, Mastodon Mark, who breaks out of his prison. Empowered with a Shining Emerald which made him immortal years ago, and with his magic, he makes plans for conquest.

Having observed the Garage Kids and the Miracle Battlers from beyond his seal, he knows he needs to deal with them before he can start his plans of world domination. He recruits General Jellyfish, former War Zard Stabber Basilisk and Quicks Emu as well as brainwashing Chief Parrot's good-natured niece Cher Parrot, Bartz Hedgehog, Pocky Seagull, Baxter Walrus, Ivy Rhino, Garcia Zebra, Axel Hawk, and assassins Lyle Fox and Blizzard Bobcat into his servants.

He sends his minions, each disguised with an illusion spell as the Garage Kids or Miracle Battlers to cause trouble and trick the heroes into fighting each other, while he gathers the Sacred and Great Orbs. The heroes however realize they are being tricked and they all set out to collect the Orbs themselves.

 * Mastodon Mark: an ancient shark. Mark was a primitive hunter who had a Shining Emerald embedded in his forehead that granted him immortality and mystical abilities. After the defeat of Baker, the magic used to seal Mark was weakened and he began his conquest. In order to deal with the heroes, he recruits several beastmen to work for him. He casts an illusionary spell on them, giving them the appearances of the heroes, so they can confuse them and force them to fight each other while he steals the Sacred Orbs and Great Orb himself. When that plan failed, his head start allows him to gather the orbs in time and uses it to become Almighty Mark. Fortunately he was stopped by Thunder and Quake and imprisoned into the Shining Emerald, then hidden into an area never to be found.
