Sally is just a mobile-suitsized REX. Sally's grenades would not work against REX, both of them use the same type of armor , although REX's armor is much thicker. No other Metal Gear was made after REX and none will ever be made, as RAY isn't a "true" metal gear so REX is the ultimate war-machine , unstopable and invincible. If Solid Snake had the oportunity to pilot a pristine REX with the aid of Otacon, no one could defeat it.
