Marshall Evan Stone III was born in Albany, New York.
When his mutant nature manifested, Marshall sought aid in controlling his body's now-protoplasmic state. Help came in the form of the Dark Beast, who gave Stone control in exchange for his services as a superhuman operative for X-Factor. Though still only a young boy, Stone used his powers to make himself appear larger and older, becoming the bounty hunter Random.
As a bounty hunter, he took down a mutant suspect, a serial killer, and Speed Demon, but didn't kill any of them.
He established himself in Albany with a housekeeper and mother-figure, Vera.
At some point, a thief killed Charlie Ronalds's parents, Harry and Robin, while the family was leaving a screening of the 1966 Batman movie. Charlie Ronalds grew up with a hatred for mutants.
