Kangaroo isn't your typical spy. Sure, he has extensive agency training, access to bleeding-edge technology, and a ready supply of clever (to him) quips and retorts. But what sets him apart is "the pocket". It's a portal that opens into an empty, seemingly infinite parallel universe, and Kangaroo is the only person in the world who can use it. But he's pretty sure the agency keeps him around only to exploit his superpower.
