Yes, we both know that Bethesda particularly like the concept of Super Mutants, tall, big-muscled, totally obsessed towards the annihilation of the human race. But because we can not see a peaceful variant, like Fawkes. Uncle Leo, Virgil, or the West Coast Supermutant?

It would be interesting not only to fight these mutants in Boston. Maybe even see them wear more "civilian clothes" such as jackets and ties, dresses in leather or even power armor, adapted to their body structure. And yes, maybe even a nice pair of shoes or boots instead of going around barefoot like savages.

At least we can see that some prefer a quieter life, "civil" rather than live as raiders and kill everything they encounter on their way.

So we could see them as "regular" settlers, or merchants and see maybe them in a bar selling drinks or food. Or even more them as bodyguards in Goodneighbor.
