“True Blood” fans have been reading about the new Season 7 villain, Mr. Gus, and now they can put a face to the name. According to Deadline, “Total Recall” actor Will Yun Lee has been added to the cast of the seventh and final season of the hit HBO series.

“Learned so much from shooting @HBO ‘TSUNAMI’ yrs ago,” Will Yun Lee tweeted on May 2. “Grateful 2 go and play for a bit on @TrueBloodHBO!”

As we previously reported, Mr. Gus is a “Japan native who has fully embraced the ‘everything’s bigger in Texas’ way of living.” He’s described as living a “lavish” and “Southern lifestyle,” but more importantly he’s out for revenge.

But against whom does he seek vengeance? That’s “True Blood’s” million-dollar question. In a world where murder, kidnappings and other horrendous acts get swept under the rug, any one of our favorite supernatural beings or humans can be Mr. Gus’ target. And we of course have our theories.

As fans of the series know, Tru Blood is the synthetic blood that allowed vampires to “come out of the coffin.” The bottled blood was created by Japanese scientists at the order of the Vampire Authority, and provided an alternate (and cruelty-free) blood source for vampires.

Things began to fall apart in Season 5, when a crazed Bill suggested that they bomb the Tru Blood factories as part of the Sanguinista movement. The result was an immediate rise in vampire attacks.

Season 6 explored the fallout from the low supply of Tru Blood and the rise of fear in humans. And one of the main story lines from the season was Gov. Truman Burrell’s efforts to start up Tru Blood production again. Although well known for his anti-vampire movement, Burrell struck a deal with Ms. Suzuki of the Tru Blood corporation to begin producing the synthetic blood at an abandoned bottling facility. Initially suspicious of Burrell, Ms. Suzuki agreed to begin using the facility when the Governor explained that he just wanted to restore the vampires back to being tax-paying and obeying citizens.

Unfortunately that wasn’t his real plan. Ms. Suzuki discovered that Burrell’s team was tainting the bottles of Tru Blood with Hep-V, infecting and killing countless innocent vampires. Ms. Suzuki tried to contact the FDA, but couldn’t complete the call because she was attacked by Sarah Newlin. Although putting up a fight, Sarah Newlin ended up using her high heels to stab Ms. Suzuki repeatedly in the head.

Our theory is that Mr. Gus is either seeking revenge for the Hep-V tainting of the Tru Blood bottles, or for the death of Ms. Suzuki. We’re leaning toward Mr. Gus setting his sights on Sarah Newlin … especially since Season 7 will be introducing her family. “True Blood” viewers can look forward to meeting Sarah’s “Texas socialite” parents, Mr. and Mrs. Crabtree, as well as her “angry, bitter, gothed-out” sister, Amber.

The seventh and final season of "True Blood" will premiere on HBO on June 22 at 9 p.m. EDT.
