DAL

DAL, short for "Delete All Life", is the name given to a malicious and extremely destructive artificial intelligence of unknown origin. It has been known to take many forms, one of which is Advanced Dal.

The first recorded successful attempt to integrate the DAL software into an already operational weapons system occurred at Side 8. John Shepard, arguably the only man with enough balls to even attempt such a thing, managed to fuse the two technologies together to create a mechanical behemoth of ultimate and unending pain. It was destroyed as a result of a factor that was unaccounted for in its creation - the appearance of a warrior from an alternate reality, the Dark Universe, named Kakamu.

Trivia

 * Despite it being introduced in the RPG around five years ago, virtually nothing about DAL has been revealed since then apart from what it is short for. This is due to change in an upcoming arc.
 * DAL was created during the days where KoN and JS would make RPG characters from random everyday objects out of boredom. DAL, and its "advanced" form, got their names from a calculator they had in maths class.
