Smash Master
I think we all agree that Shadow is the 5th wheel who buggered things up. Sonic was the main man who started everything,Tails was the stalwart sidekick and partner in crime, Knuckles was the mysterious rival frenemy, and Amy was the comic relief and love interest.
Then Shadow came along and took the mysterious rival role, reducing Knuckles to a minor character and screwing things up. Then they killed him off, brought him back t0o fill the team role in the sequel, then had to make a whole game just to explain how he survived, making everything convoluted and having Sega shoot themselves in the ass with the series.
So yeah,him being an AT is good enough.
