Strata the Hunter is a character that appears in Bakugan Battle Planet. He is a hunter for AAAnimus Inc., using controlling devices in order to capture and make Bakugan cause destruction. His main Bakugan is Aquos Krakelios, and he also owns a Haos and a Darkus Skorporos.

Once he hunted the world's most dangerous wildlife... Until he became aware of the existence of the otherworldly creatures called Bakugan. Strata has since tailored his cutting-edge hunting techniques to track down and neutralize Bakugan for sport. He’s captured a few, keeping them as inert trophies in his mansion. Using a special energy-siphoning weapon, Strata has the ability to drain a Bakugan of its power, leaving it dormant.
