===1940s=== During an as yet unrevealed adventure, the 5th-Dimensional being Dr. Nobody magically extended the lifespans of SMASH members, along with other heroes. That enabled them to remain active for decades without apparently aging. 
Members of SMASH were killed or placed in suspended animation by an alien being attempting to convert the Earth into a spaceship.
Renaming themselves (from Major to Modern), the team reformed and continued their adventures.
Equipment: None known.
Transportation: None known.
Weapons: None known.
- Ostensibly a team dating back to the 1940s, they of course are a modern invention of Alan Moore and Chris Sprouse using various public domain characters from Nedor Comics.
