Henry Russo (son)
Jigsaw has shown advanced combat skills on the same level as Punisher and Daredevil, and is one of the best street-fighters in the world. In addition, he is incredibly skilled in the use of various forms of firearms, bladed weapons, and explosives. Jigsaw's physical attributes of strength, speed, stamina, reflexes, and durability are at an exceptionally high level, that have allowed him to harm and be harmed by superhuman opponents like Spider-Man. His peak-human metabolism protects him from most diseases and allows him to heal from minor injuries in a matter of hours. His lung capacity and resistance to pain are also remarkable.
William "Billy" Russo was a professional criminal and assassin for the Maggia and Costa crime families. He received the nickname, "the Beaut," because of his good looks. After the killings that led to the deaths of Frank Castle's family, Russo was hired by Bruno Costa to assassinate another assassin who had failed to kill Frank Castle. In this attack, Russo killed all of his targets but Castle (who narrowly avoided death in an explosion). However, hours later, Castle tracked down Russo and threw him head-first through a glass pane. Russo survived; however, his face was ripped to shreds. Because of the extent of the damage to his face, surgeons had to stitch Russo's face back together like a jigsaw puzzle. In addition, Jigsaw developed a phobia of panes of glass.(Click on the highlighted names above to learn about the Punisher and/or the Maggia. Also, the top left corner of the third picture posted shows the pre-accident Russo look.)
Russo took advantage of his hideous look and took on the alias, "Jigsaw." Soon afterward, Jigsaw attempted to frame the Punisher for murder. However, his plan failed due to Spider-Man and Nightcrawler's intervention. (Spider-Man witnessed one of Jigsaw's murders and one of his victims was an old friend of Nightcrawler's). (To learn about Spider-Man and Nightcrawler, click their highlighted names above.)
Later on, Jigsaw became involved with a demon worshipper named Reverend Samuel Smith aka "the Rev." Based on healing demonstrations, the Rev convinced Jigsaw to work for him as a type of assassin in exchange for Jigsaw's face to be healed. However, when the Rev finally healed Jigsaw's face, Jigsaw was killed by the Punisher.
Soon after, Jigsaw was brought back to life by the Rev and his master, Lucifer (who in actuality was Belasco). Once again, Jigsaw battled the Punisher, and again his face was ruined when the Punisher pushed him face down into a sharp aloe plant. (To learn about Belasco, click on his highlighted name above.)
While he still worked as an assassin for criminal organizations, Jigsaw's pursuit of the Punisher was relentless, as Jigsaw saw Frank Castle's assassination as an unfinished job. At one time, Jigsaw's vendetta took a bizarre turn when the Punisher faked his death (he appeared to have been executed in prison). Furious with rage, Jigsaw briefly became a new Punisher, getting revenge on Castle's apparent killers because Jigsaw figured they had denied him of the kill he believed to be rightfully his. (The fifth picture posted is of Jigsaw dressed up in his Punisher outfit.)
Jigsaw was one of many villains to break out of the Raft (a floating prison for super-villains). While escaping, Jigsaw was seen fighting Luke Cage. Once freed, Jigsaw fought and was defeated by Tigra. This defeat led Jigsaw to form an alliance with the Hood. Together, Jigsaw and the Hood were able to track down Tigra, and the Hood beat her senseless while Jigsaw video-taped the whole thing. Then later, the Hood and his entire gang appeared at Tigra's apartment, demanding to know the location of the New Avengers' secret headquarters. However, Tigra intentionally gave them information that led them into an ambush. (To learn about the place, characters, and/or team highlighted above, just click on their names. Note: Beware of Tigra's revealing outfit on her bio page.)
Later, Jigsaw took part in an attack on the Sanctum Sanctorum, and attempted to murder Jessica Jones; however, his plan was foiled by Spider-Man. (Click on the highlighted names above to learn about the place and/or character. Note: Beware of the form-fitting outfit on Jessica Jones' bio page.)
For now, despite being a wanted criminal, it appears Jigsaw is safe from harm.This is the Marvel.com link, but nothing is currently there: http://marvel.com/universe/Jigsaw.
