When I was first watched Origins I was sure there was gonna be a part near the end in Stryker's lab when Victor like went up to Stryker and was like "I need to be stronger to beat him." And Stryker was like "I've got just the thing, I'm not sure what the side effects will be though" And say injected him with something that enhanced his mutation, made him stronger but also bulked up psychially and made him more docile. Not to be exactly like in X1, but at least giving you the impression he would eventually end up like that. I don't really know why they didn't do something like that. Unless they were gambling leaving it to an Origins 2, but it more comes across as "oh yeah they're different, who cares"
