I would assume that agents would become blocky upon entering the fic world, to fit in. And the easiest way to kill her sounds like it would be to go with something from the game's continuity: you could attack her with any of the many weapons or offensive potions in the game, set up a clever trap (preferably involving lava: it is, after all, the nether), push her off a cliff, or snap canon back and have the hostile mobs kill her.
You can look at the minecraft wiki for inspiration. :D
