Bite your bum rat-face, or I'll pound ya!!”— Kleiver to Daxter in Jak 3
Kleiver is a wastelander living in Spargus. He can be considered relatively important as he is in charge of the Spargus Garage as well as the (former) top gunner on the Spargus Gun Turret. He is a skilled racer and it pains him to give up one of his vehicles to someone else. When he first met Jak and Daxter in Jak 3, he disliked them, and considered Daxter as a potential meal, but he came to respect them as he appreciated their racing talent and skill. When Veger was made into an ottsel, Kleiver forcefully made him his sidekick.
Later, in Jak X: Combat Racing, Kleiver arrives in Kras City, sans Veger, to get another chance to beat Jak on the circuit, but he is once again defeated. Jak remarks that Kleiver doesn't do anything for free, indicating his belief that Kleiver was recruited by Mizo to stop them on the racetrack.
- In one mission, Kleiver says that his personal favorite vehicle is the Dune Hopper.
- There is an unlockable bonus called "Kleiver's Diaper". As the name states, activating it gives Kleiver a diaper.
- Kleiver has many terms he uses to refer to others, such as "Ankle-Biters" and "Small Poppies." This is in keeping with Sig's similar habit, such as referring to Jak and Daxter as "Cherries" (though Sig sounds more congenial when doing so). Still, it is also worth noting that Kleiver has an accent that is probably meant to sound Australian (most likely referencing the history of Australia as a dumping ground for British criminals) and his dialog is sprinkled with real or approximated slang meant to support this idea.
