Jeff Harrison

"Don't you think it's time that you petty humans evolved? You'd all better transcend now, or our fleet of supermen will conquer you while you're still in this lowland level. Take this as a warning."

- Jeff to Clayton Shirogane, Keith Maverick and Almark Giovanni during their first confrontation Jeff Harrison(ジェハリソン Jeffu Harison) is among one of the most dangerous threats to both Earth Land and Edolas. Due to this issue, he and his "supermen" were confined inside a time capsule centuries prior to the formation of Earth Land and stayed motionless while being locked in the lowest floor of an unnamed prison in Edolas. However, most recently, a desparate Warrod Sequen panicked due to an inevitable upcoming war expected to be waged between Earth Land and Edolas, so he reluctantly freed Jeff, believing his keen intellect was a vital asset to sealing the boundaries between Earth Land and Edolas. As expected, Jeff retaliated and escaped from the Wizard Saint's custody, committing genocides on Earth Land.

Jeff serves as the main antagonist in Fairy Tail: Enchanted's Dreaded Sundown Arc.
