Steve

Steve (no last name given) is an employee of Xavier Mace, also known as the Black Dragon, but works for the him on a thug-for-hire basis.

The Black Dragon hired Steve to go back in time with a number of other Black Dragon operatives, and have them spaced out across a century timeframe, in order to prevent Tom Swift Jr. from completing his mission of acquiring enough iridium to make a number of time travel detectors to prevent the Black Dragon's Time Bomb.

Unfortunately Steve was killed by a carniverous dinosaur in the Cretacean period.
