They could bond over their love for knowledge, with Sakura sharing her medical ninjutsu knowledge and Twilight sharing her magical research. Also, they could support each other in facing challenges that require both physical and magical skills.
A third popular pairing is Sasuke and Sunset Shimmer. Sasuke has his dark and brooding side, while Sunset Shimmer has a complex past of her own.

Twilight Sparkle is really popular. Since she's the main character in the original series, a lot of fanfictions revolve around her adventures and her trying to adapt to the human world in the Equestria Girls universe.
Twilight Sparkle from My Little Pony is also quite popular in these crossovers. Her intelligence and powerful magic make her a great counterpart to Naruto. She can have really interesting interactions with Naruto, whether it's about sharing knowledge or working together in battles.
Fluttershy could be an interesting character to include. Her gentle nature could be a contrast to Shadow's more brooding personality. It could lead to situations where Shadow learns to be more empathetic or Fluttershy becomes more assertive in his presence. Sunset Shimmer is also a key character as she has a complex backstory and her knowledge of both worlds can play a significant role in a fanfiction involving Shadow.
Sora is often a very popular character. He's the main protagonist in Kingdom Hearts, and when he's brought into the Equestria Girls' world, his heroic nature and his skills with the keyblade make for exciting storylines.

Definitely Naruto and Bayonetta. Naruto's never - give - up attitude and his growth from an outcast to a hero can be a great foil to Bayonetta's already established badassery.
