S.H.E.D. HQ: Inside

Meanwhile, at S.H.E.D., at first, it seems like nothing could possibly go wrong for the heroes, but then, Metal Sonic intrudes.

"Metal Sonic!? I thought Sonic and the others took care of it!?" Holly yells in a both confused and surprised tone.

"Wrong, my systems were only critically damaged, but due to my repairs, I am once again capable of functioning." Metal Sonic talks back. "Shadow Android, I have located our foes."

"Shadow Android? Who is he talking about?" Milly asks worriedly.

Then a robot resembling Shadow arrive.

"It seems that some of our adversaries are absent at this moment." Shadow Android said.

"We must follow the master's orders: 1. Capture the enemies, and 2. Take the Chaos Emeralds." Metal Sonic said.

"Understood." Shadow Android replied.

"We won't let you take anyone or the Chaos Emeralds." Tails said.

"Any resistance to the master's orders must be dealt with violence." Metal Sonic said.

Metal Sonic knocks Tails back towards a wall.

"Hey, leave Tails alone, you big bully!" Amy yells as she attempts to attack Metal Sonic, but he dodges and Shadow Android knocks her back into a wall like Metal Sonic did with Tails.

"Now you will come with us." Metal Sonic told the group.

But then both robots get knocked back by something.

The something is revealed to be the Beak, controlled by Baljeet and Ferb.

"Switching targets, attack the metallic bird suit." Metal Sonic said.

"Acknowledged." Shadow Android replied.

Shadow Android flies towards the Beak, but gets knocked back.

"Strength level considerably high, underestimation must not occur again." Shadow Android calculates the Beak's strength.

"Perhaps another fighter will even out the odds." Metal Sonic says as he joins Shadow Android against the Beak.

Metal Sonic attacks S.H.E.D. with a new partner, Shadow Android. The heroes are pinned against the wall by the robot duo, but the Beak comes to the rescue. Will the Beak be able to sent the robots packing, or will the robots triumph over the robotic suit? To be continued...
