I think I finally hit on a name to give Golden Age Daredevil in the MK setting. Because Daredevil is, obviously, taken, and other renames of the character havent really stuck with me.

The Danger Devil!

Or simply The Devil for short.

Let's see if it jives, hang on

Bart Hill was trained in acrobatics from an early age by his father, Alexander Hill, as he grew up as part of a traveling circus. By adulthood, he had become the show's star acrobat, performing amazing, daring feats of acrobatic skill, attempting leaps and dives no other acrobat would dare to attempt. His signature performance would regularly involve his other major talent, his uncanny skill with boomerangs. Often he would combine high flying trapeze acts with amazing trick-shots, wowing audiences across the country.

It had become a running gossip among the circus staff that he was only able to perform such feats due to a deal with the devil.

Such rumors gained terrible new contexts when one night, the circus burnt down under mysterious circumstances.

Bart dove in to the flames to rescue anyone he could, but he was the only man to emerge from the fires alive, still clad in his costume, and seemingly rendered mute by the experience.

He disappeared the next day, and only resurfaced after hunting down the criminals who had burnt down the Circus in an extortion attempt and bringing them to justice. Hence forth, he had become known as The Death-Defying Devil, a silent vigilante and unstoppable hunter of those who prey upon the innocent.

Though some whisper that perhaps it wasn't Bart Hill that emerged from the flames that night...
