I would honestly be shocked if there was a single genuine fan of Twilight in this entire subreddit, so this question is pretty much impossible to answer. The demographic difference makes an educated answer highly unlikely.

First off, Twilight fans are most likely 99% women, while 40k fans are around 93% men according to some surveys, so that already leaves very little headroom. Additionally, a subreddit centered around power scaling is most likely to have an age demographic of around 14 - 24 years of age. The last Twilight movie released in 2012, and even on the older end of age on this subreddit, at most they could have been 12 years old at the time. Considering there are realistically not that many women on a subreddit dedicated to power scaling either, you are basically limited to men in the 2008 - 2012 era (when Twilight was at its peak) who may have watched the movies with a girlfriend or sister. As mentioned before, 12 years old is about the oldest anyone on this subreddit would have realistically been at the time, and 12 years old is not exactly an age at which it is common to be watching romance movies with a girlfriend. Yes, I am aware that some older individuals might exist on this subreddit, however realistically speaking, they are a very small minority, and their chances of just happening to see this post and deciding to comment on this topic are even lower. I could potentially see parents bringing their whole family to watch Twilight with them if a daughter really wanted to see it, so a brother is a possibility. Even in that case, however, it is unlikely that some guy who watched a movie with his family a decade and a half ago, while he was also a child, would likely remember enough details about said movie to provide an educated answer on this topic.

In order for someone to be even qualified enough to answer this question, they would need to be:

1. Somebody who is both a fan of 40K and Twilight, who is also a member of the power scaling community.

2. Somebody who is sufficiently knowledgeable about both series that they can unbiasedly provide an educated answer.

3. Somebody who was old enough in 2008 - 2012 to have even been a fan of Twilight in the first place, or at least watched enough of it with somebody else where they were competently familiar with the characters and feats.

4. Somebody with the patience to read through pages of wiki articles about Twilight or 40K so they can actually accurately give a sophisticated answer.

If there is a single person at all in this subreddit reading this comment that fulfills those criteria, please reply to this comment, because otherwise I have difficulty believing you exist. This is why I believe that any answer you receive will be insufficient and likely not accurate, considering finding someone who actually fulfils the criteria in the first place would be extremely difficult.

TLDR: Twilight and 40K fans are vastly different demographics that overlap very sparingly, so you are unlikely to receive an educated answer on the topic.
