This takes place during Battle for Angel Island.

You were standing just meters away from Neo Metal Sonic’s newly made throne, attached and taking control of the Master Emerald. The island’s wind was harsh, the sky was grey and slowly sprinkling sharp rain as Sonic’s Master Mecha doppelganger stood before you. After but a moment the Mecha overlord stood up, his footsteps bold and hard, each metallic thud and step echoed through the islands as he finally laid his glowing red eyes on you.

“He took no time at all and began his monologue. Lord Eggman repaired me. Removed the rebelliousness from my coding. But you know this-we’ve clashed since then. His harsh and robotic voice took centre stage, all his sharp points seemed to shine as he lifted his arms in display. He decided to upgrade me to this form once again. I was to be his greatest weapon in the final Battle! (The final battle that took place in Sonic Forces) But I was completed too late. The war was lost. You and the rest of them had ruined everything once again. He stopped his tracks, his eyes as piercing as ever as he declared*. But now!... NOW! I have the doctors ambitions, his genius and motivation! Lighting began to boom the area, the loud and harsh patter of rain followed suit. And after I beat every single one of you, I will find my creator and deliver back to him his dynasty, I WILL SIFT THROUGH THE WORLDS ASHES TO FIND HIM, IF I MUST!” Finally a large burst of energy emitted from him, his aura surrounded as he powered up to his max.
