Hugo Coghlan (Hugo Hercules, Cú Chulainn) is an incredibly strong man and considered to be one of the first American superheroes (or "super-fellers" in his words).
When he was a young man he visited Cactusville, Texas. There he sired a child who grew up to be Desperate Dan. Hugo worked as a mercenary and assassin for hire.
In 1890, Hugo was sent to kill Captain Nemo under the orders of Doctor Nikola, but hesitated when he realized Nemo was in the middle of his honeymoon which is against one of his principles. Furthermore, Nemo hired him at a better price to kill Nikola instead, and keeping him on retainer for Nemo and his family ever since. Shortly after World War I, Hugo was hired by Clark Savage Sr. to kill Hugo Danner. Another of his employers was the Pink Child. In 1954, Hugo was responsible for wiping out the last of the giant mutant ants in America.
In 1975, he accompanied Janni Dakkar in her pursuit of the Ayesha clones. Following the ordeal, Hugo was instructed by a dying Janni to carrying out her final wish to have Hira and Manfred Mors to rule Lincoln Island until her grandson Jack comes of age.
"Hugo Hercules" was a comic strip created by William H.D. Koerner, running in the Chicago Tribune from September, 1902, to January, 1903. In the comic strip, Hugo Hercules, “the boy wonder,” would wander around the city helping those in need. He would stop runaway carriages simply by grabbing them, or catch a falling safe, or lift up an elephant.
Hugo Danner, arguably a derivative character loosely based on Hugo Hercules, was the protagonist of Philip Wylie’s novel Gladiator and the inspiration for Jerry Siegel and Joe Shuster's Superman. He died when struck by a bolt of lightning.
