I think hybrids are a very good thing in the saga, and I don't think they're that out of place. Hybrids not only have the function of pleasing the audience, but also that of deepening the message of the film: science, used in this way, is terribly dangerous. I really like the speeches that are made on the ethics of creating these creatures and on the control that Wu would like to exercise over them because he thinks he is legitimized by the fact that he made them, when in reality he cannot and never will. Believe me, there is more to the talk "these creatures are ugly, dinosaurs were better" "" "" "" "" "" "" pure "" "" "" "" "".
Specifically, I believe that E750 is the most interesting hybrid, precisely because it looks like a mistake: ugly, humanoid, hyperagressive, it almost looks like an extraterrestrial. But I don't know if it would be in the game: maybe it would be a bit out of place, but I certainly wouldn't mind.
