When I use the word "alien" I am referring to any extra terrestrial creature.
When I use the word "Alien" I mean The Alien from the Scott, Cameron ect films.
The Predator is an alien. The BSP is an alien that looks like a Predator but only bigger in a movie about Predators. Its the main antagonist, refered to as a Predator, in a Predator movie so its a god dam Predator! Fox Studios who own the right to the Predator franchise refer to the BSP as a Predator (like the one in P1 and P2) but only bigger and stronger! 99.9% of the people who will go see the movie will call them a Predator, like the one in P1 and P2, because they will resemble them but bigger and badder....so they are Predators just like Anytime and Pussyface!
Of course you can go round telling people that the BSP is not a Predator despite it looking like a Predator and being the main bad guy in a Predator movie! However don't blame me if people start slowly backing away from you trying not to make eye contact
