it had been 6 months since blaze left silver and silver helped save sonic and defeat solaris. now silver was looking for other surviving people because as of now he was all alone. meanwhile in sonic's time period shadow just performed a chaos blast so powerful that G.U.N had E-123 omega hunt down defeat and capture him and that was all that was known to the public. back to silver's time eggman nega was sneaking around an abandoned G.U.N base but then the guard robots reactivated and attaked and said ah snooPING AS usual I see! then eggman nega said i thought that would happen then he pressed a button and metal sonic 3.0 flew in just brutaly destroying theese robots while that was going on eggman nega pressed on and found a secret room as he entered he heard a clank clank clank he turned quite swiftly for a man that fat but it was just metal sonic 3.0 he said oh its you didnt see you there as he tucked his gun away again he opened the vault and entered the 5 letter password M-A-R-I-A there we go maria and prrssed enter as a pod rose up from a hole in the floor once itgot high enough it stopped and opened to reveal a black hedgehog with red stripes when eggman nega saw him he immeadiately gasped and then realized who it was it was shadow created by his decendant dr. gerald robotnik a genius who made a deal with black doom and the rest of the black arms trading a promise of chaos emeralds in 50 years in exchange for black doom's DNA to create the ultimate life form shadow the hedgehog. then eggman nega realized thats kind of racist but yet again so is his name. shadow struck him so hard that he fell to the ground unable to get up he watched metal and shadow fight metal flew right on top of the fat man and wwhen eggman nega pushed him off that activated E-123 omega and he shot wildly at shadow but he used chaos control to get behind him and he kicked his arm off then the other and finally ripped his head off. shadow looked at what was left of it and thought he had seen it before then he saw a paper underneath it he saw it andpucked it up it was a picture of him the robot and some bat girl he carried it with him in case he remembered anything. he afterwards teleported out leaving the doctor with metal sonic 3.0 who reactivated afterwards for now locked in the room.
