“Evil “ Amy AU. Classic and Modern.
The Classic Era was the one with Amy following Eggman's orders with little to no hesitation. She knew that Eggman was and is Evil, but he was so well worded when he needed her, and he always promised minimal damage if Sonic was stopped, so Amy always tried her best to stop Sonic and obey Eggman. She only failed to stop Sonic, but if Eggman needed something else of her, she did it nicely.
Metal Sonic was became less than Sonic’s archenemy and more like her guardian when time passed. At the start, Metal was usually with Eggman, just waiting for Sonic to kill him like the machine he was suposed to be, but Eggman worried for Amy —since she was only 8 years old—. Metal had her second directive apart to neutralize Sonic the hedgehog now, and it was to obey, follow and protect Amy when she went to her missions.
Grave Mistake. She used that to slowly break Metal's cold personality, and at the end of the Classic era, he was a different person.
Amy’s design is almost the same as the original, but her colours and the sublte clothing changes are with relation with Robotnik after Sonic CD.
Modern Era under the cut.
This was the start of the turning point of Amy —who is 14 years old now, since I feel 12 years for her doesn't feel correct for her in this AU—.
Eggman's plans are getting way more serious, and Amy starts to drift apart a little of the man who once she believed was like a father. She stills follows orders and Metal still protects her and takes care of her, but things aren't just the same anymore.
Metal and Amy are like siblings now, teasing each other and joking when Eggman is not around. Amy is the little shit that gets into trouble, and Metal is the one good boi who tries to get her outta trouble, but he makes it worse
And can I talk about Metal a little more? Because Amy gets to see first hand how Metal growths as a person, how he refuses to be called Sonic anymore and the way his red eyes brighten up when someone calls him nicknames. She sees Metal start to relax and adopt a more chill posture, letting his trouble past behind, stopping seeing himself as a weapon and just as a person.
She buys him the jacket in this era, and Metal uses him with the old scarf she got him. He never takes it off, just when he absolutely needs to fly. He fucking loves Amy with everything he has, she’s his best friend, his dear little sister. He won’t fucking let anything happen to her.
And Blazamy. I'm a sucker for Blazamy, even if this AU is pure slow Sonamy pining. Blaze in the AU stays almost the same design wise, just gave her a different coat because i love her original design so fucking much AAAA.
