Orangutans are usually heavier than humans (averaging 225 to 250 pounds or so) and stronger. The statistics for a 2 HD individual represent adult females or younger males, while the 3 HD statistics are for larger mature males; there will usually only be one such in a group of orangutans.

Orangutans are shy creatures and would generally prefer to be left alone, but they are physically powerful and may be very dangerous if cornered or provoked.
