Jiro Marshall
Jiro Marshall was a powered individual who showed up during the early stages of the Yokohama Disturbance. He had enhanced strength and durability—pretty standard abilities, but effective. Most fans suspect he was working as a spy for the USNA, though it's never made entirely explicit in the text.
His story doesn't last long. After his encounter with Erika and Leo, Lu Gonghu tracked him down, killed him, and burned the body to destroy any evidence. It's a pretty brutal exit, but that's how things went down during that arc.
