Hulking Metamorph

Except for also being an artifact creature and having a different power and toughness, Hulking Metamorph copies exactly what was printed on the original permanent and nothing more (unless that permanent is itself copying something or is a token; see below). It doesn't copy whether that permanent is tapped or untapped, whether it has any counters on it or Auras attached to it, or any noncopy effects that have changed its power, toughness, types, color, and so on.

If the chosen permanent has X generic mana in its mana cost, X is 0.

If the chosen permanent is copying something else (for example, if the chosen permanent is a Clone), then your Hulking Metamorph enters the battlefield as whatever the chosen permanent copied, with the stated exceptions.
