and Tom Hiddleston
here's a visual reprisentation
I seriously love this pairing
Think about their characters:
They were both brought up under false pretences, and found out that their parentage was not what they expected. This warped both of them , combined with the magic that they both wield the betrayal that they faced changed them into a more evil entity. They both suffer under the superiority of their older brothers, who hold the crown to their respective homelands. They share a common desire for the crown and are also both filled with hatred. I can't explain it much more they are just so perfect for eachother.
Here are some video representations...
