Master Chief and Cortana, as you'll encounter them in Halo Infinite.

Halo is a multimedia science fiction franchise centered around the Xbox-exclusive series of first-person shooter games. The Halo Universe has been expanded through multiple spin-off games, novels, and comics.

Set in the 26th century, humanity fights a desperate war with the Covenant, an alliance of alien races who believe humankind to be heretical. The United Nations Space Command find themselves outmatched by the Covenant's superior technology and greater numbers, but they have one advantage: the Spartans. Foremost among them is the Master Chief, an enhanced super-soldier clad in advanced power armor. Leading the fight against the Covenant, Master Chief and Cortana uncover the secrets of the mysterious Halos and their creators, the enigmatic Forerunners.
