Same scenario as the first. Batgirl is placed in Isengard along with the 10,000 Orcs. Can she defeat all of them? If not, how long can she survive?
While most of them are fighting Batgirl, a few, lets say 100, of the the Horde will be working on increasing their numbers. 15 new Uruk-hai every hour. In order stop the reproduction Batgirl must kill the 100 special Uruk-hai that maintain it.
