There are three Sonic androids in the original sonic series.
Silver Sonic (the large silver one) appears in Sonic the Hedgehog 2.
Mecha Sonic (the dangerous dark blue one) appears in Sonic and Knuckles.
Metal Sonic (the far closer to Sonic's anatomy one) appears in Sonic CD
ooooooooooooooh. master mecha sonic's or metalicx sprites? search in google. metalicx is master mecha sonic's short name.
They both have a diffrent look and metal is as big and not as strong as sonic and mecha is a stronger version of metal sonic (metal sonic the final 1 (not mecha)) Fused with all forms of him metal sonic+weaker metal sonic+Much weaker metal sonic+Weakest metal sonic = Mecha sonic

metal sonic is not in sonic 3 only mecha sonic
while Mario, sonic, and stuffwell are underground, mecha sonic breaks through the ceiling and fights them. Mario ends up saving sonic and escapes down a pipe. mecha sonic follows them. after Mario and sonic find they are stuck forever, mecha sonic fights them and takes away the emerald. he surprisingly finds out that chaos control doesnt work where he is. every one ends up escaping before mecha sonic ddestroys them.
