Oh, this is such a fun question! I've stumbled across a few Spider-Man x Scarlet Witch fanfics over the years, and some of them are absolute gems. The dynamic between Peter Parker’s quippy, street-level heroism and Wanda Maximoff’s mystical, emotionally complex power set makes for an intriguing pairing. Writers often explore how their contrasting worlds collide—whether it’s through interdimensional mishaps, team-ups gone romantic, or even soulmate AUs where their powers intertwine in unexpected ways. One of my favorites was a slow burn where Wanda’s reality-warping accidentally merges her universe with Peter’s, forcing them to navigate each other’s lives while hiding their growing attraction. The tension between Wanda’s tragic past and Peter’s hopeful optimism creates a delicious emotional conflict.
That said, it’s not the most common pairing in the fandom, so you might have to dig a bit deeper than, say, Peter/MJ or Wanda/Vision fics. Archive of Our Own and FanFiction.net have some hidden treasures if you search by tags like 'SpiderWitch' or 'Peter Parker/Wanda Maximoff.' Some authors really nail the balance of action and romance, weaving in MCU canon elements like the multiverse or the aftermath of 'No Way Home.' If you’re into angst with a happy ending, there’s a particularly moving one where Wanda helps Peter cope with his identity reveal fallout—it wrecked me in the best way.
