Again I feel like ultimately it's hard to dodge stereotypes because the Sonic cast are so prominently cartoonish (and in fairness often taking away those details tends to make them boring and lacking a 'core' per se). I really feel Amy is no more stereotypically sexist in its depiction of girls than say, the 90s Archie females were, who were maybe glamorised as competent at face value, but still largely existed as tokens or love interests, and actually tended to play old tropes perfectly straight while the likes of Amy and Peach at least make fun of a lot of them. I'd rather have a stereotypical shell but with a developed substance to them, over a progressive shell but with no real substance to back it. I feel like Heroes Amy was the 'franchise original sin', it started a lot of bad trends and had some worrying signs of bad character directions, but largely she was handled okay, if anything she got some natural development in that game. I feel like Sonic X and the spin off games that followed it tended to hinge on those bad ideas over the good too often, along with some other characters like Knuckles. What were originally quirks moderated to pepper their characters and give them whimsy were dominating their personalities and their dynamics. The gag focus also got a bit too mean spirited. Amy and Knuckles' roles in the main group often seemed reminiscent of a Cartman or Zoidberg type, that one obnoxious, pathetic character no one in the group really likes and only keeps around because they either feel obligated or because they make a fun punching bag (or in Amy's case, because they'll murder them if they don't :P). Even Cream is reflexively insulting them in Rush. Say what you will about the eras before and after, but it felt like for all their arguing and quirks, they successfully shown the cast LIKED each other to some level, even super bungling Knuckles in Boom was not just the unpopular butt monkey like his X era counterpart. I feel like they often miss the point about Amy, she never really felt like an 'AMY SMASH!' type originally, nor a smart computer girl like she is now. Amy was resourceful, her hammer was not a super weapon, but something she utilised in a clever way to keep up with everyone. She was the 'mortal' of a bunch of super powered characters, almost a super peppy Batman if you will. Amy weaponised her childlike bubbliness and her smarts with her toy hammer to be an efficient heroine and even a team leader. That side of her doesn't have to be homogenised.
