Sword Elites

Sword Elites are Sangheili warriors with Energy Swords who appear as mini-bosses in the video game series: Halo. They charge at the player with an Energy Sword with the intention of killing you, but are to be killed before they manage to reach you. Usually high ranking Elites will wield an Energy Sword, making it more challenging since higher ranking Elites have stronger overshields.
