Leonard "Wrench" Hebb was a gifted student, completing four engineering degrees before going on to get his doctorate from M.I.T.

He turned down several automakers, NASA, and foreign governments before becoming part of Team America (later renamed The Thunderiders) so he can work on applying new technologies in America.


Wrench is a genius mechanic and inventor as well as a competent motorcycle racer.

He is also a mutant who shares a mental link with the other members of The Thunderiders. The Thunderiders can project their physical strength, abilities and knowledge into a host body. This host body takes on the form of a black-leather-clad individual known as The Black Marauder.
