In the first four Alien films, we were introduced first to Ash, then Bishop (and then Bishop II) and then Call. In Prometheus we then met David. Is this just an in-joke that the androids started from A through to C? And is David somewhat of an anachronism in the sense that Prometheus is widely regarded as a prequel to Alien?
The people working on the franchise recently, at least, are aware of (and actively adhering to) this trend. From an interview with Kelly Sue DeConnick, who wrote an official comic miniseries that follows Prometheus:
Comics Alliance: Is there an android whose name starts with the letter E?
KSD: There is!
CA: Good. I’m so pleased. Because we have to have the alphabetical-order androids.
KSD: We have solved that problem for you. Scratched that itch.
Indeed, the android was named Elden.
As for David's name being an anachronism, why should it be? The androids appear to be named in release order of the films, not in-universe chronological order
