A week later, Bill, still leading the Dark Egg Legion group in Downunda, had learned what happened in New Mobotropolis and secretly sent the news to his old comrades, the Downunda Freedom Fighters. Bill retreated into a nearby chair, feeling nothing but concerned about his faraway friends, he had received a strange package from his minion, which it was in a form of a black suitcase with line markings glowing cyan and the X lighting a different shade of blue. Suspicious yet curious, he ordered his minion to leave him in private and opened up the briefcase, unveiling a slightly spherical violet-glowing stone. His concerned eyes widened in horror as he was about to meet the new change coming upon him.

Bill groaned as his body trembled, and began to throb and grow! Muscles packed into his puny platypus frame, which grew tighter against his grand master suit. Bill’s moans of muscled pleasure attracted the attention of nearby platypus patrol soldiers, who burst into his office with weapons drawn. They were stunned to see their leader roaring body burst out of his pants, and the rest of his suit tore off giving way to ripped gorgeous muscles. The soldiers didn’t know what to think as their commander rose higher, over doubling then in height, and over twenty times as much muscle mass!

Bill clutched his head in pain feeling all these new sensations. The surges brought both pleasure and pain, but something was happening to his mind. Bill’s thoughts of evil which he put on for Eggman were becoming real. Bill wanted to dominate and take over. But he would never serve Eggman, no. Bill felt the intense desire to overthrow Eggman and become ruler himself over all Downunda. Bill also felt a strange tingling in his body. Almost instantly, he knew that it was the cybernetic upgrades Eggman implanted in him being destroyed. Eggman’s technology was inferior to the power of this stone. and with the cybernetics gone Eggman no longer had any hold over him.

As Bill’s growth stopped, the platypus guards starred. Bill began to chuckle, then threw his head back laughing evilly as he rose to his feet. He turned sneering at his guards with one hand holding the stone. Bill commanded his soldiers to approach, and touched them with the stone causing each of them to experience the same. Once they finished Bill made an announcement commanding ALL platypus soldiers to report to him immediately. Within the hour Bill’s platypus army began to grow, and grow, and grow. They lost all their robot upgrades, and gaining massive muscles, but nobody seemed to care. Somehow Bill remained the biggest of the bunch, rooting his place as leader. The army smirked awaiting his orders. Bill chuckled and held the stone. His thoughts turned to the other side of the law. the freedom fighters. His old friends. Bill grinned, recalling a secret rendezvous with them in an hour to exchange information. Bill gave orders, gathering a group of soldiers to accompany him to the sewer.
