Powers: Keen Marlow possessed enhanced strength (lifting 1000 lbs.), sufficient endurance to swim the English Channel, enhanced reflexes, and agility rivaling that of a mountain tiger. He was a master of disguise, as well as an accomplished investigator and detective.
Bio: None entered.
Notes: Marlow's last name is occasionally misspelled as "Marlowe".
Editions of the Official Handbook of the Marvel Universe have clarified that all three versions of the Destroyer — Keen Marlow, Brian Falsworth, and Roger Aubrey — were active during World War II, with Marlow allowing Falsworth and then Aubrey to simultaneously use the Destroyer identity so as to tactically confuse the Axis.
While the character is sometimes called "The Mighty Destroyer", the character's name is simply "The Destroyer", just as "The Invincible Iron Man" is "Iron Man", "Incredible Hulk" is "Hulk", etc.
