# Mister Terrific
**Mister Terrific** is a superhero legacy in [DC Comics](https://www.edgepedia.org/dc-comics), held by two characters united by the motto "Fair Play": Terry Sloane, the [Golden Age](https://www.edgepedia.org/golden-age) original who debuted in 1942, and Michael Holt, the modern successor introduced in 1997. Neither bearer has superhuman powers; both rely on extraordinary intellect and physical training.[1](https://dcuguide.com/Mister_Terrific_%28Terry_Sloane%29_Chronology) • [2](https://www.dc.com/blog/2025/05/27/fair-play-everything-you-need-to-know-about-mister-terrific)

## Terry Sloane, the original
Terry Sloane was created by writer Charles Reizenstein and artist Hal Sharpe and first appeared as a backup feature in Sensation Comics #1 (January 1942), the same issue that carried the start of [Wonder Woman](https://www.edgepedia.org/wonder-woman)'s starring series.[1](https://dcuguide.com/Mister_Terrific_%28Terry_Sloane%29_Chronology) • [6](https://comicbook.com/comics/news/mister-terrific-essential-comics-dc-superman/) His backup stories ran through Sensation Comics #9 (September 1942), with titles such as "The One-Man Benefit Show," "The Crooked Carnival," and "The Fall of Ferret McGee."
Sloane was a street-level hero whose adventures centered on frauds, racketeers, and petty criminals rather than supervillains.[1](https://dcuguide.com/Mister_Terrific_%28Terry_Sloane%29_Chronology) Later retroactive continuity placed him in the wartime All-Star Squadron, and he appeared in that series in 1984 and 1986.[1](https://dcuguide.com/Mister_Terrific_%28Terry_Sloane%29_Chronology) According to DC's own retrospective, Sloane's death left a void in the superhero community that became the starting point for his successor.[2](https://www.dc.com/blog/2025/05/27/fair-play-everything-you-need-to-know-about-mister-terrific)
## Michael Holt, the successor
Michael Holt first appeared in 1997's The Spectre #54, written by [John Ostrander](https://www.edgepedia.org/john-ostrander) and penciled by Tom Mandrake.[2](https://www.dc.com/blog/2025/05/27/fair-play-everything-you-need-to-know-about-mister-terrific) Readers meet him feeling suicidal after his wife Paula was killed in a car accident. The Spectre responds by showing him the life of Terry Sloane, and Holt takes up the Mister Terrific name to continue Sloane's mission of inspiring and helping at-risk youths.[2](https://www.dc.com/blog/2025/05/27/fair-play-everything-you-need-to-know-about-mister-terrific)
**Fair Play.** Holt adopted Sloane's "Fair Play" motto and had it embroidered on his costume as a reminder of the value. His first costume consisted of jeans, sunglasses, and a black bomber jacket with "Fair Play" on the back; he wore it for only his first two appearances before switching to his black-and-white outfit in 1999's JSA #5.[2](https://www.dc.com/blog/2025/05/27/fair-play-everything-you-need-to-know-about-mister-terrific)
In his first outing as Mister Terrific, Holt confronted the Spectre itself, one of the most powerful beings in the [DC Universe](https://www.edgepedia.org/dc-universe), betting his own soul that a group of gang members could still be redeemed; the Spectre agreed and left the criminals to him.[2](https://www.dc.com/blog/2025/05/27/fair-play-everything-you-need-to-know-about-mister-terrific) Holt went on to join the [Justice Society of America](https://www.edgepedia.org/justice-society-of-america) and eventually served as its chairman, remaining a main character of Justice Society series for roughly a decade.[4](https://dc.fandom.com/wiki/Michael_Holt_%28New_Earth%29) • [7](https://www.dccontinuityproject.com/mister-terrific.html)
## Abilities and T-Spheres
DC's character profile lists Holt's abilities as genius-level intellect, advanced technology, gymnastic ability, and skill as a fighter; he has no superhuman powers.[3](https://www.dc.com/characters/mister-terrific) He grew up in a poor family, earned multiple PhDs in various fields, founded one of the world's leading tech firms, and became an Olympic gold medalist.[3](https://www.dc.com/characters/mister-terrific) Later coverage puts the count at 14 PhDs in DC Comics.[5](https://www.techradar.com/streaming/entertainment/superman-cast-and-character-guide) DC Database describes him as having "a natural aptitude for having natural aptitudes," easily picking up complex skills that others spend lifetimes perfecting.[4](https://dc.fandom.com/wiki/Michael_Holt_%28New_Earth%29)
His signature invention is the T-Sphere, a flying robot sphere that responds to his vocal commands. T-Spheres serve passive functions such as holographic projection and communication, and weaponized functions including explosives and electrical charges.[3](https://www.dc.com/characters/mister-terrific) In screen adaptations the spheres create holographic projections, hack into other machines, and emit energy bursts.[5](https://www.techradar.com/streaming/entertainment/superman-cast-and-character-guide)
