Jabari (Avatar fan character)

Jabari aka "the mechanist" is a scientific engineer who studies lost tech, entranced by the age of Sugizai when technology made bending obsolete. Though he'd rather use his knowledge to better the lives of the four nations, Reiner has strong armed him into crafting weapons for the Neo Equalist party. He joins the Red Lotus to put an end to Reiner's tyranny and finally start harnessing lost tech for the greater good.
