Elizabeth Olsen and Tom Hiddleston both won't back down when asked who among their "Avengers" character will win if they squared off.

In an interview with The Hollywood Reporter, Olsen insisted Scarlet Witch will win hands down.

"I think Scarlet Witch would win -- she's one of the most powerful people in the universe," the actress explained.

Hiddleston didn't agree.

"The thing is, you're dealing with someone who's a witch, which is admittedly impressive biographically," he pointed out. "But you put that up against a god, I'm just not sure that there's a fair contest. He's an immortal being, so my chips are firmly in Loki's corner."

But while the British actor seemed confident about his "Avengers" character, he's not sure though how long he'll be able to portray the character.

"I never quite know whether people want to see him again or whether people want to move on," he told MTV. "I can't really take the temperature on it," he admitted."

Given the chance though, he promised to try and reinvent the character.

"I would try not to repeat myself," he explained. "I would try to do something new. I never want to feel like I'm retreading the same steps."

While it remains unclear if there would be an onscreen reunion for Elizabeth Olsen and Tom Hiddleston in the Marvel Universe after "I Saw The Light," the pair might be reunited at the Savannah Film Festival. As reported by Variety, "I Saw The Light" will be one of the films to be featured in the festival.

Olsen and Hiddleston were rumored to be dating back in July as they were caught by photographers having dinner in London. But during the Toronto International Film Festival, the actress denied the dating rumors.

"I mean, we definitely are friends and we've known each other for about four years," Elizabeth Olsen told Refinery 29 about her relationship with Tom Hiddleston. "And we happened to be at a restaurant at a wrong time having dinner. We all go out to dinner."
