This article should not be confused with Frog-Man.
Leap-Frog is a supervillain alias used by two different minor characters in Marvel Comics. While wearing the Leap-Frog suit, the wearer receives enhanced durability and strength and the ability to leap great distances. They are both enemies of Daredevil.
Vincent Patilio
Tired of his lack of success as an inventor, Vincent Patilio designed himself a frog-like costume incorporating his latest invention: electrically powered leaping coils. Calling himself Leap Frog, Patilio was defeated in both attempts at a criminal career by the hero Daredevil. After being defeated by Iron Man, Patilio was sent to jail.
Patilio served his time in prison and then returned to his wife Rose and young son Eugene. Rose's salary kept the family financially solvent until she died of cancer. Barely making enough money to support himself and his son, Patilio fell into despair. At this time, his son Eugene donned a version of his costume to attempt to create a heroic career as Frog-Man. Patilio was proud of his son for capturing the villain Speed Demon, but his pride turned to disapproval as Eugene continued to serve as a superhero. Patilio forbade his son to adventure as Frog-Man.
When the villainess White Rabbit reappeared, Patilio went undercover to join her gang on behalf of the police, which brought him into conflict with his son, who, as Frog-Man, tried to take down the White Rabbit. Patilio ultimately defeated the White Rabbit with the help of his son.
Presumably, Patilio remains retired from adventuring.
Buford Lange
Buford Lange is an abusive father who stumbled upon an abandoned Leap-Frog costume and began a short-lived criminal career. He was created by Brian Michael Bendis and David Mack.
Lange fought Daredevil on a rooftop, only to be electrocuted by his own autistic son, Timmy, who didn't want to see his hero, Daredevil, hurt. Lange fell off the rooftop and into a garbage truck on the street below and died.
He was resurrected by The Hand and joined an assault on the S.H.I.E.L.D. helicarrier which resulted in its destruction. He was killed again by Wolverine as were most of the super-villains and heroes The Hand were using in the attack.
