The Questers (クエスター, Kuesutā), were robotic-armored versions of two of the Ashu Tribe, affiliating independently. The Questers possessed the ability to create wavelengths with the Gordom Engine, which interfere with the power of the AccelSuits' and GoGo Vehicles' Parallel Engine, and can melt into the ground. The two soon left Gajah and became freelance Treasure hunters, using the Gordom Engine technology and the Precious for their benefit of eliminating the human race, making the Questers the most dangerous of the Negatives. In Task 42, after the Homunculus was destroyed, the Questers challenged the Boukengers to battle, with Gai being defeated by Eiji, while Rei was destroyed by the Dual Crusher, finally destroying the remaining Ashu Tribe on Earth. Eiji would later set up gravemarkers for the Questers out of respect.
