First of all, it has Arnold. He's the ultimate action movie star. Why? Look at him. He looks like an Adrenalin and steroid inflated monster. He's hardly human.
He rarely has feelings or emotions, and when he does, they deliver witticisms and puns, care for the welfare of others and inspire the most ridiculously devoted loyalty. He's human we know because he's mortal. Other than that, he could be a cyborg (and as been in other movies).
And then there's his German accent. It's most important. While his Austrian looks could easily blend him into America, his voice keeps him at an exotic distance.
But Arnold is always funny, always self-deprecating, and never ever full of himself. In Predator, his puns make the violence fun. Yes, he makes the violence fun at times. It's a powerful personality who can make stabbing a man and telling him to "Stick around" a good time. This isn't objectionable. It's necessary for the ultimate action movie. It helps prioritize the violence, show the audience what is horrible and what is trivial.
