Aliens in movies with deliberate images on their bodies??

If you are going to try and concoct a conspiracy out of it have at least 2-3 instances of what you are intrigued by.

That insignia on that one alien might just have been an idea that sounded good at the time but just didn't come on video properly, drown out by lighting or something. .

Doods, thats just a buff alien. Its just fake alien abs....its gonna be ok.
