Ermac is my favorite character in Mortal Kombat. It was firstly because I liked the color green, and his telekinetic glow attracted me. The telekinesis idea was so creative. I love his bandage mask and the red/black attire.
But what I never get enough of is his gravelly voice in MKD and MKA. It's so distinct from other characters, and I'd always laugh when he grunts after getting hit.
