Gog

Gog is a mutant of low intelligence, who is the Brother of Scot. Due to him having no skills or strengths, the only thing that he can do is simple tasks for his brother, who treats him poorly but better than anyone else would. Gog travels with Scot as a Companion in Roads Less Travelled, offering assistance in building and maintaining the group camp.

Background
A mentally subnormal mutant creature, who is mentally three years old and physically looks like he went off years ago.

His mutated body provides all sorts of disadvantages. His giganticism oblitorates his coordination, his deformed body affects his strength and motor skills, his brain is a barely functioning bit of flesh that is crushed between the big wad of flesh that holds it in place, his eyesight is relatively poor, he walks with a limp and his webbed hands make it practically impossible to pick anything up.

Yes, Gog has received a rather bad role in life, however, he is not completely useless. Those who show him kindness are usually rewarded with treasure as he has a knack for finding it. Nobody knows when or where he finds it but he seems to be an idiot savant, when it comes to prospecting. He can find all kinds of items from caps, medical supplies, ammo and even the occasional weapon or armour piece.
