Dragon

Dragons are a planned mob. Notch hinted during the Spider Jockey update that he will add Dragons to the game. It is also mentioned that dragon lairs may be an addition. There has been no previous work that he has displayed to show that he is currently working on dragons, and they remain a potential work-in-progress until future updates come. It also should be noted that one of the random messages on the title screen is "Absolutely dragon free!". Notch has also stated that achievements could lead into a large cumulative task "like killing a dragon." It is also possible that they could be the "scary monster" coming in the Beta 1.8 update, although this is slightly unlikely as Jeb seems to advise against having dragons as was said at the dreamcast presentation, at the time 31:34.
