The scientist, whose civilian identity is Nathaniel Essex, will likely face off the actor Hugh Jackman's character Logan in "The Wolverine 3", reported AceShwobiz.
According to the sources, it is believed that the crazed villain will be portrayed by "Dom Hemingway" actor Richard E Grant.
The director, James Mangold, seems to confirm the speculation as the post-credit scene, which features a representative of the Essex Corporation obtaining a vial of Wolverine's blood from the ruined Alkali Lake facility, is said to have a direct connection to the third "Wolverine" film.
