Theories

Metal sonic the only way for metal sonic to move that fast is if he was light weight the only metal that is light enough but still strong is aluminium now what are vibrators made of ... Aluminium now with all the gears moving as fast as they are metal sonic would essentially be a living vibrator and you dont see a dick on him so hes made to take dick and who made metal sonic Dr.Eggman why else would Dr.eggman make metal sonic if he wasnt trying to make a living sex doll of sonic. so in theorie Dr.Eggman has a Sonic kink.   I'll take no questions thank you
