Monstro

Real Name: Monstro
First Appearance: Pep Comics #40 (July, 1943)
Original Publisher: MLJ
Created by: Irv Novick

Origin: 

Monstro was a powerful, but peaceful martian who visited earth when he accidentally trapped himself in a spacecraft bound for our planet. Monstro created pandamonium amonst most of the earth citizens he encountered when he set out on foot in New York, and the police assumed him to be the vanguard of an alien invasion. Monstro tried to escape, but was tracked down by The Shield. When The Shield attacked him, mistakenly believing that Monstro was threatening his partner Dusty the Boy Detective, Mostro crumpled into a fetal position. Monstro decided to stay on Earth for a while and The Shield attempted to look out for him during his visit. However, The Shield quickly became annoyed with him and Monstro set out on his own for a few weeks in March. He naively attempted to help a number of earth men, but was taken advantage of by swindlers. Soon after, he decided to leave the earth.

Although he is not aggressive, Monstro demonstrated tremendous strength, speed and athleticism, likely on a superhuman level. He was highly resistant to injury, at least enough to shrug off the bullets of police firearms without harm. He had the ability to read minds, which in turn allowed him to instantly learn English. He also had the ability to morph his appearance to look like any human (or anything else he wanted to resemble). He also had x-ray vision, allowing him to see through solid matter.

Despite his power, Monstro was quite timid. He revealed that he had high blood pressure and that he suffered a nervous break down at one point.

Original Publisher: Quality
Created by: Alfred Andriola

In 1919, identical twin brothers Michael and Lance Gallant were born in New York City and both possessed T-shaped birthmarks on their left wrists. The boys remained close growing up. Later, during the Second World War, Michael enlisted in the Air Force as a pilot. Unfortunately, on his his 23rd birthday, he died when his hanger exploded. Kim Meredith, his fiancée, and his brother, Lance, saw the tragedy and grabbed Michael from the flames, only to have him die in his brother's arms. Lance wanted vengeance. The Fates of Greek mythology witnessed Michael's death and decided to turn Lance into their champion. Soon, Lance is visited by Michael's ghost, who told his brother they were still linked. So, Lance decides to call himself Captain Triumph and become a crime-fighter.

He was assisted once by his sidekick, Biff, who dressed like a clown.

Captain Triumph's enemies included Baron Bragg, Colonel Fishama, Dr. Marfree, Hypnotic Eyes Khor, the King - the Jack of All Trades, Krogar, the Man Who Conquered Flame, Men of Darkness, Mr. Pointer, Mr. Weary, the Porcupine, Rafree, Raven, the Red Mask, Silent, Silvertip, Sitok the Green God of Evil, Supremo, the Veil, Spade the Ruthless, Tyrant of Toar Valley, Vanishing Vandals, and Yorvey.

Powers and Abilities:

If Lance touched his birthmark, the brothers would merge and gain superpowers. When merged, Captain Triumph's powers included superhuman strength, endurance, flight, invulnerability, and invisibility.

Touching the mark a second time would separate them. Michael (as a ghost) was intangible and could turn invisible.
