Headscratchers / Tekken 5

• Who sent the Jack robots to kill Heihachi and destroy Honmaru? And why?
  • It was confirmed in Tekken 6 that it was G-Corp, presumably to remove the closest thing the series had to a Big Bad (and was also possibly targeting Kazuya as well). Kazuya, in return, proceeded to slaughter the G-Corp members who presumably sent the Jacks against him, and take over the company too.
