Kumarbi
Kumarbi was one of the primordial members of the Friendly Council, and is widely credited as having "seeded" the concept of agriculture in humanity on at least three separate occasions.
He was killed in 2016 by consuming a Super-Poisoned lemon while patrolling the Black Sea.
His ability, "I Found a Way" allowed him to grant humans the idea of selectively breeding plants to augment consumable caloric material therein. He could also remove this idea from a person, thus erasing the concept of agriculture from early human groups that were approaching an unwanted level of cognitive advancement from surplus carbohydrates.
