The Avengers exchanged glances, unable to believe the scene before them.
Enemies so hard to deal with had suddenly been wiped out, just like that?
And they had died in perfect unison-so perfect it was eerie.
Tony worked up his courage and scanned the nearest Chitauri soldier's corpse with his Iron Man Armor.
"What the hell? No external injuries, and the internal organs are completely intact..."
"Even its vital signs are normal. It's just... dead."
Elemental powers like lightning, fire, and ice were still within their understanding. After all, they left traces, and everyone knew how they hurt their enemies.
But that eerie green light had gone completely beyond anything they knew.
No explosion, no impact, not even any destructive force.
Just a gentle flash of green light, and then... all the enemies were dead?
They had died neatly, cleanly, without even a struggle.
What was that supposed to be?
A mass alien heart attack?
A chill shot from the soles of their feet to the tops of their heads, making their scalps prickle.
"Wh-what kind of magic is that?"
Thor could not help asking.
Though he was a warrior and had seen plenty of magic, such eerie magic that killed without a sound still filled him with profound fear.
Especially when the green light appeared-he had even felt his soul tremble.
As though... he had encountered some natural predator.
"The Avada Kedavra Curse."
Hermione's voice was soft.
"No wounds, no burns or freezing. No fancy tricks at all. It has only one effect..."
She paused, her gaze sweeping over the Chitauri corpses.
"Anyone struck by it dies instantly."
"No matter how powerful you are or how strong your body is, if it hits you, you die."
The Avengers listened with their hearts pounding.
Tony swallowed, his throat feeling dry.
