User blog comment:Drawde83/Vamp is still a vampire/@comment-6512-20100902080629

Splitting up pages would only make things convoluted and confusing for new users. There are literally no benefits I can see in doing this.

Also, Big Boss, Ocelot and Vamp should not be on that list. Big Boss' personality only changes from how it was in Metal Gear and Metal Gear 2, but those games aren't 100% canon anymore anyway. Only our perception of him changes from how Snake portrays him in MGS1, and MGS3 is meant to show us why he is the way he is in MG1&2.

Ocelot's "source of arm changing" is an actual progression of the plot. It's not a ret-con.

And Vamp was never a supernatural being. The game even goes on to state that's he's called Vamp because he's a seducer, not because he's a vampire.
