Once Upon a Time guest star Greg Germann recently spoke about the "electricity" between his character, Hades, and Zelena (Rebecca Mader).

Sunday night's episode of Once Upon a Time will present flashbacks to Hades and Zelena's relationship. Hades goes to Oz when he learns of Zelena's special abilities, hoping he can strike up an alliance with his wicked counterpart. In the process, he will develop a deeper relationship than he ever could have anticipated.

Germann spoke about this connection in a new interview with E! Online:

"I think Zelena and Hades are, there's definitely an attraction there between the two of them. There's an electricity. Or thunderbolts. Or fire, depending on what world we're in, I guess," he said.

He also joked that their relationship is so strong that they should be on Dancing With the Stars next.

Moving on to the topic of playing such an evil character, Germann admitted that he's having a great time.

"It's just so much fun to play," he said. "As Hades, what can't I do? I kind of can do whatever I want to do and it's a kind of power there. For the time being, at least, I've got everyone under my thumb."

While Hades may seem unstoppable for the time being, Germann did allude to the fact that everyone has their weaknesses and limitations.

"For now, at least, you can see [the heroes saying,] 'What can I do?' Well, there's nothing they can do. I'm a god. Go ahead, give me your best shot," Germann said. "So, for now, they can't. But what [showrunners] Adam [Horowitz] and Eddy [Kitsis] are doing with all these characters is they're showing, whether it's with Rumple or, I don't know, any of the characters, there's a weakness everywhere. Superman has Kryptonite. So Hades must have something, but you'll have to watch to find out."

Once Upon a Time airs Sundays at 8 p.m. ET/PT on ABC.
