4) Dr. Zander Rice
Logan isn’t the type of film to have an out-and-out supervillain, but it does have an amoral scientist pulling the strings behind the scenes. Richard E. Grant’s Dr. Zander Rice is the chief scientist at Alkali-Transigen and is responsible for wiping out mutantkind – his team planted mutant-gene suppressors into popular food and drink products.
He also mentions that his father worked for Weapon X and was murdered by Wolverine. It’s likely that he’s referring to Logan’s breakout from Alkali Lake where he massacred everyone in sight. We previously saw this in X-Men: Apocalypse and this is also how it plays out in the comics, where Rice Sr.’s murder is what propels Zander to take his vengeance on the mutant race
Though it isn’t referenced in the movie, it’s likely that Alkali-Transigen are a branch of Essex Corp – the company that took Logan’s blood from Alkali Lake in the post-credits scene of Apocalypse. We can assume that Transigen used that blood to create Laura and that Essex Corp’s CEO Nathaniel Essex AKA Mr. Sinister is still waiting in the wings.
