Super Freak
I've wondered myself if it was supposed to be a part 4 version. SS does do that from time to time. For example, their original Freddy figure technically was more accurate to the part 2 look then 1 having the red eyes and all that. However it is confusing because with Myers they included the bed sheet that he wore in the original Halloween....sooo not sure what their real attempt was.
I think they started out as an "all encompassing" version (hence the confusing accessories), and then based on the popularity, expanded from there. I think that's why we got a Freddy's Revenge Krueger and why his, and the Pt. 3 Jason's boxes were non-specific to a movie whereas latter releases were.
There's also the possibility it could've been a matter of, "We need you to make a Myers, but don't use Shatner's likeness. We have it with Star Trek and since they never got it for Halloween, that could complicate things."
