[Ascent] [Help] Setting NPC/Creature Flags

I am looking for a certain Flag (if possible) that would allow me to have an NPC/Creature spawn and be hostile to everything.

Scenario:
I wish to have an NPC/Creature spawn and then path through a zone but be flagged Hostile to both Alliance/Horde npcs and Mobs in the area. So this "super npc" would attack any mob in its path as well as any NPC.

Reason:
I want to have this one NPC spawn then path and kill everything that gets in its way. I want to path this NPC through a few towns and outposts killing all NPCs and mobs that come in its path. I want to add a little "fun" in the lowbie areas with some rare hostile spawns.

I do not know if there is a Flag that will flag something hostile to everything. I am hoping someone would know of the top of their head if there is such a flag.

Any help or suggestions is greatly appreciated in advance.
Thanks

yeah man, just select npc and type ".modify flag 0 1", the flag for hostile to everything is "0" and the "1" is for save it.

Then if you want that all these npcs get this flag for example illidan bug, illidan doesnt attack and cannot be attacked, select illidan and type ".modify flag 0 1" and if you want all the illidans that you will spawn get the same flag just type ".npc export 1".

Remenber the "1" in the end of the command is for save the command.

Good luck (y) sorry for my bad english xD
