Teanchi is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He is a human resident of Adabat and a Guardian of the Gaia Keys, which are essential to access the Gaia Temple.
Shattered World Crisis
One day, Teanchi and his family's ancestral home was reduced to rubble by the Shattered World Crisis. While his family was safe and could live with Kaeo until further notice, Teanchi entered a depression over losing his family's legacy, and spent days and nights moping over his loss at its wreckage. As such, when Miles "Tails" Prower and Bunnie D'Coolette came to Teanchi to get his Gaia Key, he wanted nothing to do with them. They soon returned through, with Teanchi's whole family, who tried to cheer him up. After hearing Bunnie's own sad background, Teanchi realized he still had what mattered: his family. Cheered up after a tender family moment, Teanchi had Kaeo fetch his Gaia Key for Tails and Bunnie, and bit the duo farewell, intend on rebuilding his home.
Later, Teanchi witnessed Adabat's Gaia Temple being risen from the ground and summoned by Dr. Eggman, who intended to utilize all seven temples for his own ambitions. He and his family would later watch the world being restored by the Light Gaia.
