Disagreed. He's liquid metal, sure, but he can be affected by electromagnetic fields. Mercury, as far as I know, is not magnetic. He also has many different colors which serve different functions (and therefore he cannot simply be mercury with colorings or whatever). As for his viscosity, I haven't studied enough of that to know for sure, but I'm gonna guess high (whatever a "high" viscosity means). Even when he melted into the ground (or should I say roof?) involuntarily, he didn't fall apart.
