9) Sabretooth
Sabretooth was completely wasted in the first X-Men movie, and made no further appearances until the critically panned X-Men Origins: Wolverine. It was there that the character finally got the treatment he deserved thanks to Ray Donovan star Liev Schreiber, but the script let him down in a big way. All of the right ingredients for the definitive take on the iconic villain were there, but not utilized correctly. Could the next X-Men movie make things right?
I’d like to think so, and reintroducing him here would be a really smart move on Fox’s part, as would bringing back Schreiber. There have been rumblings that he might reprise the role in Wolverine: Weapon X next year, but that hasn’t been confirmed, so a return in the new timeline is entirely possible. The fact that the character has been taken down a more heroic path in recent comic books could also nicely set the stage for a change in status quo for him on the big screen too.
