Actually, that's wrong. FILE 0 allows Chara to freely manipulate his statistics. It's an ability they have and it can work without someone else pushing the button. Because that's how it works. Sans, being capable of hurting Frisk, was most likely because of KR/KARMA, has the same functionality it has within the game. Tiers don't matter when it comes to hax, unless said hax is weak and can be easily countered. KR, at least from what we've seen, can't be countered so easily.
I believe you're missing the point about Bete's illusions. She can create them within the current, not put them in some sort of Genjutsu or whatever you're trying to make it out to be. If Betty was within a dire situation in which she'd need to escape/kill off a character, using illusions would probably be a good way to do it, but it's not always guarenteed that, just because she has those illusions, that she is given the W.
If you would kindly look at VsBattle Wiki, which I most likely assume you get your stats from, 7-B is within the range of 1 Megaton of force all the way to 6.3 Megatons of force. So, to have her in the range of 7-B after being a 7-C level character, she'd HAVE to be a maximum of 7-C in order to even scratch the surface of 7-B. So, going off of that, she'd probably have a good AP tiering of about low-end 7-B, 10 Megatons of force with HATE or even higher due to her collecting SOULS over time.
With that, the multiplier for HATE would actually make a lot more sense than you think it does. Even if the multiplier for HATE, said on the wiki, isn't from WoG, it'd effect all people who have HATE, making the argument of what the multiplier is, fanon or canon, to be irrelevant at this point as it wouldn't change much in grand scheme of things. Unless HATE has a variable power (more than it already is as the power HATE gives is dependent on the wielder's cooperation), then I could strongly say that you have a point.
