Mecha Sonic and the Chaotix were in an egg mobile looking for the Source of the metal sonics
"Man, this thing is cramped." Vector said, "Is this the only thing that you have?"
"It's the only thing that would get us there in a decent amount of time." Mecha sonic said
"Are we almost there?" Charmy asked
"Yes." Mecha Sonic said "When we get there...Run like hell."
"What do you me-" Vector began
The egg mobile swiftly dodged a missile
"Time to abandon ship!" Mecha Sonic said as they jumped off and landed directly on top of the G.U.N base
Mecha quickly took out the turrets on the roof before making a hole in it
"Jump in." Mecha sonic said
They entered the hole and ended up in a cell hall
With only one cell
"Oh about time someone showed up!" Doctor Eggman said
"How...You're supposed to be dead..." Mecha Sonic said
"I get that a lot." Doctor Eggman said, "Now get me out of here!"
"And why should we do that?" Vector asked
"Because I have information!" Dr. Eggman said
"Fine." Mecha sonic said
Vector took the bars off the cell
"Well, that's emasculating." Dr. Eggman said "Moving on I said the kai chip was the strongest metal sonic upgrade. That was a lie, the neo chip is, which for that one I said it could take on the project shadow meaning they would send it to stone allowing him to reprogram it."
"That is good information." Vector said
Just then the alarms started going off
"We need to Boogie out of here!" Dr. Eggman said
"Not yet." Mecha sonic said
"We're going to die if we don't!" Vector said
"...You guys go I'll destroy this place." Mecha sonic said
The Chaotix ran out of the building with Doctor Eggman
Mecha walked into a room with a bunch of metal sonic parts and prototypes
On a desk was a chip labelled "Fusion"
He put it in his head as the guards ran in
"Brothers...Lend me your aid." Mecha sonic said
The room was engulfed in a bright light
As they got outside the base it suddenly exploded
And standing in the rubble was a complete mecha sonic no different parts just the original form
"I...AM..."
Mecha Sonic unleashed a shockwave
"TURBO MECHA SONIC!!!!" Mecha Sonic yelled, "I'M GOING TO LONDON!!!"
He then flew off
Taking advantage of the distracted chaotix Dr. Eggman ran to the egg mobile and flew after him
"Should we be worried about that?" Espio asked
"We should be worried about getting to London." Vector said
Meanwhile Sonic and his allies arrived in London
"Things are going to be a lot harder than they were last time." Stone said, "They fortified their defences since last time."
"No issue for us!" Sonic said
"It's more than that they reinforced their barrier so that not even the echidna can break it." Stone said
Just then stone got a notification
He checked his watch (Which everyone else looked over his shoulder)
BRING MY LATTE
"No...There's no way." Sonic said
"That's impossible..." Knuckles said
"How is he alive?!" Shadow asked
"Who?" Eri asked
"I'll be right back!" Stone said
Stone quickly ran to where the crab was hiding
"...Oh he definitely has the hots for eggman." Sonic said
After a few minutes stone returned with a latte and a minute after that Dr. Eggman appeared
"Doctor!" Stone said "You're alive!
"Hello, stone." Dr. Eggman said, "Now mind telling me why the pests are here?"
"G.U.N tried using the metal Sonics they created using your stolen blueprints to capture all alien life forms on Earth." Stone said
"Incorrect. They teleported me out of the eclipse cannon and They had me hack into my own files before throwing me in a cell." Dr. Eggman said "The nerve of those wannabe weenies."
He turned to sonic
"But if I'm going to work with this rodent. I need something in return." Dr. Eggman said
"Really?! What about the quill I just gave you?!" Sonic asked
"Got rid after sending my grandpappy away." Dr. Eggman said
"Fine." Sonic said before pulling out a quill
Dr. Eggman took it and swapped metal's power source with it
"There we go much better!" Dr. Eggman said, "Now where is that other robotic rodent?"
Suddenly turbo mecha appeared and slammed into the barrier surrounding the G. U. N base destroying the barrier
"Oh...Right on cue." Dr. Eggman said
"Let's move!" Shadow said
Soon they arrived in front of the base
Where Commander Rockwell was waiting
"Well well well if it isn't Rockwell..." Dr. Eggman said, "How sad that you had to rob me to get the tech needed to beat a blue menace."
"Hey..." Sonic said
"Don't underestimate us, doctor." Commander Rockwell said
Just then a bunch of metal sonics landed behind her with one landing next to her
"You're outnumbered." Commander Rockwell said
"Heh, no problem!" Sonic said, "We'll take you all on!"
Just then the metal sonic next to Commander Rockwell grabbed her by the leg and slammed her into the ground
"Enough of this. I've evolved past you. I'm walking on my own now." The G.U.N Metal Sonic said "And I'll start by absorbing this entire facility!"
"What?!" Commander Rockwell said "I ordered your creation! You'd turn on G.U.N?!"
"Make no mistake I'm simply following my orders...The extinction of all alien life forms...INCLUDING HUMANS!!!" G.U.N Metal Sonic said before rushing inside the building
People began to Run out of the building as it distorted and changed into a new form
"Oh, this isn't good..." Doctor Eggman said
the metal of the building began to turn red as it became the G.U.N metal sonic
When it was completed Titan Metal Sonic had been born
"Oh no..." Sonic said
Titan Metal Sonic let out a roar
(A/N titan metal sonic is the one from knuckles chaotix)
Oh boy
