Tony Masters (Earth-4678)

Tony Masters, also known as Taskmaster, is a renowned contract mercenary, hired by a mysterious organization to monitor Spider-Man and determine whether he was worth trying to recruit. To achieve this, he submitted Spider-Man to many challenges, ranging from facing waves of enemies to deactivating bombs and spy cameras placed across New York. Eventually, he fought Spider-Man himself to see if he was recruitable yet and fled afterwards.
