This is a muscle growth series focusing on characters from the entire universe of Sonic the Hedgehog, including the less known ones.

Description:
The Egg Army in the Northern Oceans had already been a bane since their establishment, but things went from bad to worse when everyone in the entire division and even Razor the Shark were suddenly transformed into big fiery brutes, hellbent on making chaos across the ocean by causing lava geysers and explosions. It had become so devastating that the entire region was on an instant evacuation.

Few days later, Coral the Betta's home was severely affected as well, so she and her young companion Pearly the Manta Ray quickly packed their things and prepared for their leave, but they were confronted by their former friend Razor. Expecting the worst, Coral had Pearly swim away as fast as she could while the betta fish had to distract the shark somehow, but Razor wasn't interested in going after her. Sometime afterwards, Echo the Dolphin started the search with Coral the Betta's place as it was nearby Meropis, only to find in horror that Razor had already turned the pacifist Coral into a warmongering brute. Coral turned to her helpless apprentice Pearly with an evil smile, prompting Echo to charge at the big betta. Razor tried to stop her but Striker put a stop to that. Echo then quickly brought Pearly out of the cave, followed by her captain, and then the angry aquatic monsters who gave chase. Pearly was eventually brought to safety to Meropis, but at the cost of losing Echo to Akhlut's army, i.e. having her transformed into a big, muscular but loyal brute.

Two hours later, Echo and Akhlut began plotting a frontal invasion against Meropis, when Razor and Coral took word of it and informed the former two about Coral's cave connected into the city via a secret passage underneath (which was Razor's intention of invading Coral's home in the first place), much to the dolphin's shock as it was something she and the rest of her fellow guards had never been aware of, neither was the royal family themselves. Still, Akhlut insisted on the frontal assault, but agreed to assign a quarter of the main forces to follow through Razor's suggestion. Such the attacks would be executed at night where the lighting would be dimmer in the city, so as to catch the Meropis guards off guard. Coral on the other hand agreed to assist the assigned warriors into the city.
