TNT and Dan the Dyna-Mite are the secret identities of chemistry teacher and track coach Thomas N. "Tex" Thomas and his student Daniel Dunbar. While working together with some "radioactive salts", they discover they are charged with atomic energy. Thomas is charged with positive energy, while Dunbar is charged with negative energy. Thomas makes a pair of rings which keeps the energy dormant until they are touched together, at which point the pair gains enhanced strength, speed, and resistance to injury, and the ability to generate different forms of energy. Thomas generates heat, while Dan can generate short bursts of electricity. One of their villains is the evil Crime Clown. The series ran through Star-Spangled Comics #23.
Post-Crisis
TNT was revived as part of Roy Thomas's All-Star Squadron, and its spin-off, The Young All-Stars. After TNT and Dyna-Mite had been active for a few months, they are summoned by the All-Star Squadron to participate in their first general meeting. Their participation seems to have been limited to attending meetings and little else until April 1942, when Liberty Belle, as chairperson of the All-Stars, asks TNT and Dyna-Mite to look into Axis espionage activity in Colorado. Here, they meet future All-Star member Iron Munro, but TNT is killed by Gudra the Valkyrie, a supernatural agent of Adolf Hitler. TNT is posthumously awarded the Medal of Honor, leaving Dyna-Mite to work with Munro and other members of the Young All-Stars. Keeping Thomas' ring, Dan finds he can activate his powers by slamming both rings together. In 2010's DCU: Legacies #2, TNT and Dyna-Mite are revealed to have been founding members of the Seven Soldiers of Victory. How this retcon affects their histories, such as the previously established death of TNT and Dyna-Mite's Young All-Stars stint, has not yet been revealed.
Current version
The latest version of the character is featured in Grant Morrison's Seven Soldiers project. Calling himself Dyno-Mite Dan, Harris D. Ledbetter makes an online purchase of what he believes are TNT and Dan The Dyna-Mite's rings, and joins five other heroes in Seven Soldiers # 0. Sadly, he is killed with the rest of his team. His rings are actually working fakes made by Cassandra Craft.
Powers and abilities
After being charged with atomic energy and making contact with Dan the Dyna-Mite, TNT has enhanced strength, speed and resistance to injury. He also has heat generation.
Other appearances
Despite some confusion, TNT does not appear in the 1993 four issue mini-series The Golden Age, written by James Robinson and drawn by Paul Smith. This series is set during the period of McCarthyism and, much as he did in The Young All-Stars, TNT is said to have died during World War II. The similarly named Tex Thompson has retired from superheroics and gone into politics. Thompson's former superhero allies eventually discover that his brain has been replaced with that of the Ultra-Humanite, and he has transplanted the brain of Adolf Hitler into the now-superstrong body of Dan the Dyna-Mite.
