Dark clouds emanate from the sky, and a storm started to brew. In a base on a distant land, Dr. Ivo Robotnik also known as Dr. Eggman is preparing his latest evil plot to take over the world into achieving his dream of creating his utopia "Eggmanland." While finishing up his mass army of ridiculously looking robots and air fleets, a mysterious figure slyly entered his hidden base, preparing to encounter the doctor.
Eagerly to unveil his evil plot to the world, Eggman said, "Hahahahaha, with my indestructible fleet and my army of robots, I will take over the world! This time no one will stop me! I know I've said this thousands of times before but this time no one, not even Sonic, would stop me!" Suddenly the mysterious figure appeared behind him. "Hello doctor, who are you calling nothing," the mysterious voice said very menacingly. Eggman quickly looked behind and noticed a shadowy figured that resembled Sonic. "Sonic, not you again! I haven't even started my evil plan. You annoying pest, you always get in the way."
The figure appeared from the shadows as he crept closer preparing to attack Eggman. Eggman noticed the individual was actually Metal Sonic.
"Metal Sonic?! What are you doing here?" Eggman said. Metal Sonic replied, "You have failed to defeat Sonic for many years due to your incompetence. Now it's my turn to get rid of Sonic. But first I need to get rid of you."
As Metal Sonic inched closer to the doctor, Eggman quickly yelled, "Guards seize him." A hoard of Eggman robots rushed in to assist the doctor and started their attack toward Metal Sonic. Metal Sonic quickly evaded each of the robots pathetic attempts into assaulting him and quickly made mincemeat out of them by performing a series of homing attacks. One by one they have all become a number as they fell. After the assault, all that was left was scrap metal, and a black mark on the floor.
Metal Sonic then quickly approached in front of Eggman after the brawl. Eggman fretfully said, "What are you going to do to me?" Metal Sonic quickly grabbed Eggman and obtained some of his DNA. Metal replied, "By using this DNA, I will take your form as a disguise. My plan will be apparent in due time." Metal Sonic then shoved Eggman into a dark room and locked it to prevent him from escaping.
Metal Sonic demolished his way out of Eggman's base and prepares to start phase two of his malevolent scheme of eliminating Sonic. Metal Sonic aims to gather the DNA of animals, most notably Cream's chao Chocola, and Big's frog Froggy.
After Metal Sonic acquired the animals when their respective owners when they weren't looking, Metal Sonic used Eggman's DNA to transform himself into the doctor himself. He then proceeded to make a message of informing Sonic that he will conquer the world in three days. This was an attempt to lure Sonic into following him to take his DNA along with his closest friends to finally achieve his perfect form.
Meanwhile, back in Eggman's secret base, the doctor stayed their thinking of an elaborate plan to escape Metal's clutches. He began using leftover scrap metal on the room he was trapped in to build a communicator to find assistance.
Eggman wondered, "Who in the right mind would be stupid enough to assist me into escaping." The first person that came to his mind was Knuckles, but he ultimately decided to use Team Chaotix as his guinea pigs because of their limited history together. He created a robot called the Egg flyer from scrap to deliver one of the communicators to Team Chaotix. The Egg Flyer left through the window that Eggman was too fat to fit through to deliver the message.
"When I get out of this room Metal Sonic, I am going to put you out of commission," Eggman said very ominously.
Author's Note: This is my first story. Feel free to give me any criticism, advise or suggestions. Why did I chose to write about Sonic Heroes? If it wasn't for this game, I wouldn't be the sonic fan that I am today. This game gave me the urge and inspiration to continue playing sonic games. Before this game came out, I haven't played a sonic game since the genesis era. This game reintroduced the franchise to me, and I felt obligated to write about this game as my first story. This story is basically my own take on how Sonic Heroes should have been like.
