Ok, just a quickie: Watching MK9 competitive tournaments, I've seen that pretty much every Ermac player picks his alternate costume, with the cloak and hood. Just coincidence, or there is some hitbox issues?
I pick the Hood one because its original, still looks like a ninja with the mask but its more like a ninja thats on fire and has AK-47 for arms and bazookas for legs.
The first costume looks like he has duct tape on his head. Shang Tsung dropped the ball there and tried to cut corners.
The MK1 Costume is nice but after the initial "wow cool" factor, its just blah.
