It’s been nearly a year since Iwan Rheon’s Ramsay Bolton was killed off “Game of Thrones,” but he’ll play a villain on a different epic sci-fi series this fall. The Welsh actor is playing Maximus on “Marvel’s Inhumans.” While his character is interested in power, Rheon notes that Maximus and Ramsay Bolton are rather different.

“When you get asked to do something for Marvel and it’s such an interesting question that although on paper might seem quite similar to Ramsay Bolton or whatever, he’s very different,” Rheon told CBR. “He’s a politician more than anything. He’s not a vicious person just going around doing things because he can and he wants to.”

“Inhumans” will follow the royal family of Attilan, who are humans with alien DNA that gives them unique powers. Black Bolt (Anson Mount) is king, but his brother Maximus organizes a military coup that forces his family to flee to Hawaii. The difference between Ramsay and Maximus, however, is that Maximus believes he is helping people and deliberates the consequences of his actions — which is also why Rheon does not feel like his character is a villain.

“Maximus is very considered,” the 32-year-old said. “He’s a politician; he thinks. He doesn’t do his own dirty work, he manipulates people to do things for him. He doesn’t run into a room with a knife. That’s not who he is. So I guess there are fundamental differences. He’s not evil. He doesn’t want bad things to happen to people. He’s a young, passionate man.”

Maximus must think through things. He’s at a disadvantage compared to his family members because he doesn’t have powers (which is a big departure from the comics). Rheon revealed that his character’s Inhuman genes were taken away during Terrigenesis, so his strength has to be mental rather than physical. After all, he can’t physically fight his brother, who can kill with just his voice.

While seeing Rheon as another antagonist will be a familiar feeling for audiences, Rheon took the “Inhumans” role because he felt the character would be a new challenge. “What’s the point of being an actor if you don’t take on these roles? It’s being part of a completely different world and create a whole universe that you exist in. It’s a very different thing,” he added.

Another difference between the two characters will be their accents. Rheon told Den of Geek that he had to blend in with the other American actors for this project. “Yeah, that was kind of a challenge because I had to ask myself how he would speak,” he said. “Obviously it would be an incredible coincidence if everyone on the Moon had American accents, but I’m not really worried too much about that. He’s got an American-ish twang, but as he grew up on the Moon. I’ve gone a bit Moon-ish with this one.”

The first two episodes of “Marvel’s Inhumans” will hit IMAX theaters on Sept. 1 and stay on the big screen for two weeks. On Sept. 29, ABC will start airing all eight episodes of the mini series. “Marvel’s Agents of S.H.I.E.L.D.,” which first introduced Inhumans, will return after the new series wraps up.
