I'd love to see Knuckles wrote in all "You know what, Sonic? I'm taking the Chaos Emeralds. You can do this without them, and stop relying on them because every time you do Robotnik somehow gets hold of them again and uses them for evil. Screw you, I'm hiding them where they won't be found once and for all, for everyone's good" but then fanwhiners about Super Sonic et cetera. Spoiler Sonic gets the emeralds in the end, but Knuckles is back to being his rival/foe without the gullibility. Sega, let me write this shit.
