Which are the characters with the worst development in Alien / Predators movies and EU?

[Master Chief]

The characters in Alien: Covenant and the characters in The Predator.  I didn't care for any of them.

In AVP 2004 they wastefully kill off the characters with any potential before our eyes that they just used time setting up, I would call that not just non-character development like Requiem, like Prometheus, like Covenant but active anti-character development.
