Who is Steven's best friend on "Steven Universe"?

Connie Maheswaran is Steven Universe’s best friend and one of his closest human companions. She first appears as a shy, book-loving girl who becomes more confident through her friendship with Steven and her involvement with the Crystal Gems.

Connie’s relationship with Steven develops beyond ordinary friendship. Steven teaches her about the strange and dangerous world surrounding Beach City, while Connie helps him understand human life, responsibility, and emotional growth. She eventually trains with a sword and becomes a capable fighter, despite having no magical powers of her own.

A frequent mix-up is calling Connie a Gem or a member of Steven’s family. She is human, and her parents are doctors. Connie also becomes Steven’s sword-fighting partner, allowing them to fuse into Stevonnie. Stevonnie is not a separate character but the fusion of Steven and Connie, and the form represents their trust and emotional connection.
