There is no official card named Iron Giant in Magic: The Gathering. If you meant a large artifact creature, an equivalent would be Steel Hellkite or Colossus of Sardia—both are colorless artifact creatures with high power/toughness.
Reason: Both are big colorless artifact creatures, like a theoretical Iron Giant.
