First and Foremost, someone who could gives us tons of food, with little chance of radiation, and while we're at it, shelter. My number one is.....
1. The Genie
Our one stop shop for survival, hell he can even undo the apocalypse, but where's the fun in that? Really all you need is him, but we are gong to limit our three wishes to a large city like shelter (For other survivors who we would love to help) and a fresh supply of water, and crops that could be harvested year round.
2. Our Combat Expert, Goku
Our watchful protector, or starving guardian, Goku, the Super Saiyan god will defend us. His huge appetite and lust to train and have a fair fight will hurt us, but there's no one better to defend us from injustice!
3. Our Team Leader, Paragon Commander Shepard!
Man or Woman, Commander Shepard is on of the most accomplished leaders in fictional history! He/she gives great speeches and can inspire even those much more powerful than him/her - selves. Who better to lead the suriviors of humanity, with the help of a ultra powerful alien and a magical being?
