Don't underestimate the power of love.
Just ask Steve Rogers, whose entire, almost century-long mandate was to reunite with his soulmate in Peggy Carter. We can't, however, deny the impact of the actual reunion between the couple, as the end of Avengers: Endgame provided us with all the feels. Love in the Marvel Cinematic Universe is carefully constructed, and often results in mainstream recognition for both the characters and the actors portraying them.
The Infinity Saga provided us with great instances of romance being established and built on with subsequent films. Even though some have fallen flat (sorry Bruce and Betty in The Incredible Hulk), others have become personal favourites.
As we look to the future, and with Disney slowly but surely reeling in Marvel characters from other studios, there is potential for subsequent lovers to become the apple of our eye. With new set photos showcasing a budding romance between Kit Harrington and Gemma Chan's characters from the upcoming Eternals film, there is clearly a rich history here to sift through.
Although no pairing can totally replace Tony and Pepper, these new couples can surely stand alongside them in the MCU.
The romantic possibilities are endless. It's just a matter of ensuring the right characters get together on-screen first...
10. Doctor Doom And Scarlet Witch
Move over, Vis. There's love to be had here.
On a serious note, Wanda Maximoff is poised to become a central figure in the MCU, post-Infinity Saga. Not only does she have her own Disney+ show in WandaVision later this year, she will star alongside the Master of the Mystic Arts in next year's Doctor Strange in the Multiverse of Madness. Both of these MCU entries have the potential to be reality-bending enough for Wanda to snap, and turn to the dark side.
If the House of M narrative ever gets adopted into the MCU, we could see it retconned in a way that allows Wanda to get with Victor Von Doom. If he is indeed being set up as the next big bad of the MCU going forward, their brief engagement can add some truly dramatic tension to the respective storyline.
We've never truly seen a couple within the MCU on the side of evil before. A Wanda and Von Doom relationship can be nuanced enough to the point where we not only feel terrible for seeing them cause chaos, we actually root for their love to prosper.
