Who would win - a pack of 10 male, full grown, gorillas, versus a single full grown african lion? The arena area consists of a 50 foot diameter steel cage, with bars that are 1 1/2" thick, cage is 30 feet high, and bars are roughly 6 inches apart. The arena floor consists of packed dirt, generally dry, interspersed with a few trees that are 25 feet tall (oak saplings). The gorillas are all in their prime age, without any physical blemishes, as is the african lion. No outside interference is allowed (no fire hoses, people yelling, etc.). The fight starts off with the 10 gorillas being raised into the arena via a floor platform, in a cage, which then drops once the platform is fully raised. The lion is likewise raised into a similar cage, 25 feet away from the cage where the gorillas were raised in. The gorillas are all part of the same pack, therefore already have an established hierarchy with an alpha male as their leader.
