Herkers

 are a type of mutant in Sunset Overdrive.

Summary
Herkers are large mutants, strong and excessively powerful. The virus has managed to augment their strength at the expense of intelligence, making them a threat as long as you're standing still or within attack range. The Herker has an extremely strong arm and a weaker, secondary arm; their primary attack is to use their strong arm to hurl other mutants and debris at the player from range. In close-quarters, they also use this arm to smash the ground and punch. They are best dealt with at range.
