Every team needs a muscle, this just so happens to be The Courier. Surviving on little food an drink, The Courier has lived in the wasteland for quite some time. He's managed to do it all on his own, with little help.
Every team needs a brain. Quick, sharp wit and humor. Sherlock Holmes can help re-build society in an imaginative sort of way. He can keep the team from eating dangerous food, and would know what to do if we ran into any enemy or predator.
Every team needs a driver to get them where they're going. And Dominic Torreto can do that without a question asked. Nuff' said.
