Lenny O'Brien

Lenny is the one responsible for making Experiment 42, and he made traveling dimensions possible. He is a brilliant 21 year old scientist, and he has made many other devices but nothing like Experiment 42. He is actually really shy and doesn’t really get much credit for the amazing adventures. He tries to keep his friends safe, but they never listen to him. He is quite lonely, but some times he will meet someone from an other dimension. Even though Lenny is a push over  in the first season, later on he learns that he is the most important one of the crew. Tetradi seems to have a soft spot for him, could he know some thing we don’t know?
