Sai

Sai is a brand-new Marvel character who debuted in 2025 alongside Laura Kinney's Wolverine, quickly crossing paths with heavy-hitters like Hulk and Namor. Their own series, Sai: Dimensional Rivals, suggests a story rooted in cross-dimensional conflict.

Fresh off a 2025 debut in the pages of Laura Kinney: Wolverine, Sai is one of Marvel's newest arrivals, introduced by creator Giada Belviso and immediately dropped into extraordinarily high-powered company — sharing adventures with the likes of Wolverine, Hulk, and Namor. With their own series, Sai: Dimensional Rivals, already on the shelves alongside appearances in Expatriate X-Men, this character has hit the ground running with a footprint that suggests Marvel has real plans for them. Ten appearances in and already headlining solo material — Sai is a Modern Age newcomer absolutely worth watching from the very beginning.
