Fractured Identity

Any enters-the-battlefield abilities of the copied permanent will trigger when the tokens enter the battlefield. Any "As [this permanent] enters the battlefield" or "[This permanent] enters the battlefield with" abilities of the copied permanent will also work.

If the copied permanent had {X} in its mana cost, X is 0.

The tokens copy exactly what was printed on the permanent and nothing else (unless that permanent was copying something else or was a token; see below). They don't copy whether that permanent was tapped or untapped, whether it had any counters on it or Auras and/or Equipment attached to it, or any non-copy effects that changed its power, toughness, types, color, and so on.
