Strongarms are Silvers who possess superhuman strength. Their bodies are enhanced in durability to crush, lift, throw, and catch objects of immense weight.
"Strongarms are perceptors with enhanced strength and durability well beyond the normal range of human capability. Strongarms are brawlers beyond nature, best suited to the arenas of Norta or border patrol between hostile nations." -Veronica Roth, "War Storm" "On Silverblooded Abilities"
