Movie Sonic x Reader: The Sonic Brothers 2

Prologue

In the mushroom planet, Robotnik was busy preparing 'mushroom tea'. It had been 243 days since Sonic and (y/n) sent him into this planet and he has been planning a scheme to get out. Sonic's quill was still with him, and that, is what he would use for that.

He always had a giant stone beside him which was his mushroom 'Agent Stone'. He plays chess with his reflection, kind of defines a mad scientist turning into a madman, and he does a lot of other stuff.

On that day 243, he was creating a complex machine that will send a shockwave that will alert beings from other planets and make them come here, that way, he'll be out of there.

Finalizing his invention, he used Sonic's quill to power up the engine and it sent a giant shockwave up space, but in the process, got him affected as he screamed like maniac being thrown down to the ground and went unconscious. Meanwhile, the shockwave sent a stream of light through space so people from other planets nearby will be able to notice something going on down there for sure.

Night had fallen and Robotnik is still unconscious. Suddenly, a ring portal similar to that of Sonic and (y/n)'s appeared right in front of him and emerging from it were a group of tribal like scavengers.

They saw the unconscious Robotnik and the leader went ahead to see if he would be alive, but he remained, still. Then the leader spotted the blue quill in Robotnik's hand and bent down to grab it when Robotnik suddenly woke up and smiled like he was expecting them, which....he was.

He activated the traps he set for them. They caught the first and the second scavenger and they were sent flying in the air. The third one wanted to take him on but just then, Robotnik called on Agent 'stone' as he activated the last trap. The stone came flying towards the third scavenger and knocked him unconscious.

Robotnik saw the ring portal was still open and licks the quill, making it shock him before he made a run for freedom.

But just then, he saw a strange figure and stops dead on his tracks as he braked and fell.

Lo and behold, the figure turned out to be an anthropomorphic red echidna with glowing red eyes and Robotnik looked shocked at the sight.

The echidna's eyes turned back to normal purple as he looked at Robotnik with a sour scowl. He noticed the blue quill in his hand.

Echidna: Where did you get that?

(Robotnik looked at the quill and replied)

Robotnik: From two little menaces from the planet called Earth. (The echidna looked at him sternly) I'd be happy to show you the way.
