Blade, Elektra and X-23 are in fact the ones from the movies (New Line's Blade, Fox's Daredevil, Logan). In my headcanon, Gambit is from Earth-838 and Human Torch is a variant of 2000s' F4 movies, because he is weak, losed very easy to Pyro. In 2000s' F4 movies he is very strong, he do the Supernova, etc.
Then, I hope we see the Human Torch with the 2000s Fantastic Four in Secret Wars, in a cameo at least.
But the movie wants to tell us that the Human Torch is, in fact, from the 2000s movies, since the movie is an homage to the Fox movies, they just nerfed him.
