"I will cut off your head and mount it on the wall as a trophy!" - Safari Boss
The Safari Boss was an unused enemy in Luigi's Mansion. The boss would have particularly have appeared as a European Hunter. The enemy was scrapped because it was too dark for an E rated Game. However, Nintendo has claimed that the idea was "never" in the game.
Unfortunately, only beta (which now can only be obtained by piracy) has the answer of whether or not this was true.
