Tate and Liza (Japanese: フウとランFu and Lan) are the tag-battlingPsychic-typeGym Leaders of Mossdeep City in the Hoenn region. Due to them both being the Gym Leader of Mossdeep City, all battles against them are Double Battles. When you defeat them, they give you the Mind Badge. This badge is sometimes mistaken for the Soul Badge due to that both badges are heart shaped. All of their Pokémon are dual-typed.
Because of the calamities all Gym Leaders had a meeting, they talked about which Team is good, Team Magma or Team Aqua, but they didn't attend it because they were at Mt. Pyre guarding the Sacred Orbs.
In the anime
Tate and Liza first made their debut in "AG099: It's Still Rocket Roll to Me!". They were still twins though Liza bragged that she was the older of the two, which irritated Tate. The twins relate to both May and Max in their own way, with May and Liza being the older siblings and Tate and Max being younger siblings. Tate had to guide a shuttle down when Team Rocket attempted to steal it.
They battled Ash in Solid as a Solrock with their mom as the referee. Though they got of to a rocky start at first they eventually got in synch in their rematch. Unfortunately they lost to Ash thanks to a improvised move called "Thunder Armor".
