History of character has not yet been written.

- This version of Mister Scarlet, including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
- Mister Scarlet was created by writer Ed Herron and artist Jack Kirby for Fawcett Publications. In 1953, National Periodical Publications settled a long-running lawsuit against Fawcett citing that the character of Captain Marvel bore too much of a resemblance to their own character, Superman. After settling the case (by agreeing to no longer publish Captain Marvel), Fawcett discontinued publication of their entire comic book line and Mister Scarlet lapsed into obscurity. In 1972, DC Comics licensed many of the Fawcett characters, including Mister Scarlet, and established that they existed on the fictional parallel world known as Earth-S. The Fawcett characters made several appearances throughout various Silver Age DC titles including Shazam, World's Finest Comics and Justice League of America. In 1991, DC bought the Fawcett characters (including Mister Scarlet) outright.
- Mr. Scarlet and Pinky were one-time allies of the Justice Society of America and Justice League of America when their three worlds were threatened by King Kull and various villains.
