Tyrannosaurus Rex

A big green two-legged dinosaur.In TR1 he's more like a giant enemy that you must be really careful about, and in TRA he is a Boss.It also appears in TR2 and TR3.

Tactics
The T-Rex has many ways to kill Lara, so it's really a death wish to stay near it.

Tomb Raider
There's a cave in the valley where you can take shelter and shoot him at the same time.It's the best way to kill it.

Tomb Raider 2
There are two at the same time! To safely kill them, stay in the little hole where the third secret was.

Tomb Raider 3
Right after you grab the key that was in his nest, he appears.Run as fast as you can to the small cave with a lever (it is right at the side of the slope that you used to get down) to kill him from a distance.Staying in the deep water is also a safe way to kill him.
