(Mecha Knuckles is a robot copy of knuckles and when you first meet him he disguises himself as knuckles but instead of red fur and white gloves his "fur" his a pink ish red with yellow gloves his real form is gray/sliver ish metal armor with red eyes and a white circle around some of chest and has a red core in his chest and is able to shoot missile out of his mouth) You see knuckles but looks different his fur is a bit pink and his glove are yellow and says hey trying to replicate knuckles voice but it sounds robotic
