A villain published by DC Comics. The Top first appeared in The Flash #122 in 1962.

Roscoe Dillon was a professional criminal. Realizing that he would never achieve the level of success he wanted as a normal criminal, he decided to become a supervillain, but needed an edge. He had always been fond of toy tops as a child, and decided that spinning would be a cool gimmick, and so designed a costume and some weapons based on tops and named himself The Top. Dillon was not the brightest of criminals.

Inexplicably, the Top's early crimes were a success. He became rather infamous and decided to strike in Central City, putting him in conflict with Barry Allen, the Silver Age Flash. Dillon was defeated and sent to jail and upon his release began working with other foes of the Flash as part of the Rogues Gallery. He also began to date Captain Cold's sister, Lisa Snart who was also a professional ice skater.

During this time, Dillon found that spinning increased his intelligence. Why this happened and how has never been properly explained, but never one to look a gift horse in the mouth, Dillon began to use his new intelligence to plan craftier and more elaborate crimes, but continued to be defeated by the Flash. Eventually, Dillon's mind developed the ability of mind over matter and he realized that this might be the key to finally defeating the Flash. What the Top had not taken into account was that his new powers also made him highly sensitive to the Flash's vibrations and on his first outing with his new powers, the Flash's vibrations caused his brain to overheat and him to die.

Roscoe was not going to let a little thing like death keep him out of the game though. He has revisited the land of the living on a number occasions, taking over the bodies of the recently deceased. He first attempted to kill the Flash by taking over the body of Barry Allen's father, who had been caught in a car accident and who had died for a minute. The Flash tricked Dillon into trying to possess him and allowed the Flash's father to return to his body.

Years later, the Top tricked the hero Hawk of Hawk and Dove into helping him, convincing Hawk that he was Hawk's brother Don. The Top caused a car accident that killed U.S. Senator Thomas O'Neil and he jumped into O'Neil's body. The Top used O'Neil to attempt to become president, by running as vice-president and then killing his running mate. He was stopped by the new Flash Wally West and presently is imprisoned in a mental institution.
