As Protector of the Universe and de facto defender of Earth, the Kree Captain Mar-Vell has triumphed over foes large and small.

But when Mar-Vell is diagnosed with cancer, he finds himself face-to-face with a foe that even his vast might can't defeat...and both he, and a universe that loves him, must rally together to accept the inevitable.

Plus, look back at the seminal battle with Nitro that infected Captain Marvel years before - and, in the midst of a battle with Titan's planet-sized computer system, now corrupted by the madness of Thanos, witness the budding romance between Mar-Vell and his true love Elysius!
