The Warp Gate is an object essential to game play in the Jak and Daxter series. They are used to teleport to a different area, and are usually connected with two different warp gates.
 Jak and Daxter: The Precursor Legacy
In Jak and Daxter: The Precursor Legacy, the Warp Gates can be found in every single hut of a sage, as well as in Gol and Maia's Citadel and Geyser Rock. Jak and Daxter use them to travel to the different worlds after traveling there at first on a Zoomer. They are not seen being used by enemies such as Lurkers, but it is possible that they used them to get to the Citadel.
 Jak II
Warp Gates do not appear very often in Jak II, but they do make a few appearances. One example of this is when Jak and Daxter are told by Onin to go to the Precursor Mountain Temple and locate the three sacred Precursor Artifacts. There is a Warp Gate when Jak first exits the City Walls, and the connected one is on top of the mountain's first ledge, up near the top of the Mountain Temple.
They can also be seen (not used) in Sandover Village, during the first cutscene of the game. If the Sandover Village Glitch is exploited, Jak is able to go next to the Warp Gate, but he is never able to jump into it and travel elsewhere, such as the other Sage's Huts or the Citadel.
 Jak 3
Warp Gates only appear in one place in Jak 3, and that is the Temple of the Monks. However, there are quite a few of these in the Temple. They are used by Jak and Daxter to travel throughout the Temple of the Monks and avoid the enemies, like the Dark Makers and Metal Heads. They are not seen elsewhere in Spargus City, the Desert, or Haven City and the adjoining areas.
