The terror! After struggling your way through Vault 87, battling vicious super mutants and tentacle-vomiting abominations, you don't feel inclined to have mercy on anything in this hellhole. The hulking mutant Fawkes is no exception, sporting bared fangs, a skeletal face, and flesh straining to cover up his way-too-huge muscles. Another equally horrifying mutant named Uncle Leo is also known to wander the wasteland, and can easily take you by surprise. Encountering either of these two, especially Fawkes when he has a giant metal beatin' stick in hand, is grounds for bowel evacuation.
The truth: While it is largely wise to fear Fallout's super mutants--who will, let's be clear, do their best to kill the bajesus out of you--Fawkes and Uncle Leo are flowers in a field of shit. Both have suffered greatly due to their condition, but have done their best to overcome it. Fawkes, for instance, has put all his energy into learning about the world and is extremely intelligent, while Uncle Leo tells his story and gives charity to anyone he encounters. Aww, what a nice guy!
