When Nemesis appeared, Thanos breathed a sigh of relief.
It seemed escaping the Marvel Universe had become urgent enough for her that she was willing to fight someone else to do it.
Darkseid and Daoist Ziyun tensed the moment they saw Nemesis.
She looked far too much like Thanos.
No one would have questioned it if they had claimed to be husband and wife.
They both had purple skin, proud bearing, and nearly the same height.
So their first thought was that Thanos had brought her in as backup.
Thanos did not care what they thought. He looked at Nemesis and said, "Help me drive them back, and I'll agree to your terms."
"Good."
Nemesis nodded and turned toward Darkseid and Daoist Ziyun. A strange energy churned in her hand.
Seeing this, Daoist Ziyun immediately said, "Stay out of this, and whatever he's promised you, I'll match it."
Nemesis gave no answer. Purple energy shot from her hand instead.
Her energy was called Revenge Power, and it had a remarkable property.
Darkseid swung his fist and shattered the mass of energy with a punch wreathed in black power.
He seemed to have dealt with it easily.
Darkseid began to underestimate her.
But the next second, searing pain surged through every nerve in his body, and his expression shifted.
"What kind of energy is this? It hurt me in a way I couldn't even detect!"
Nemesis smiled faintly, and more purple energy streamed from her hand.
"I call this attack Revenge Power. Anyone who attacks Revenge Power gets hurt.
"And the damage ignores all defenses."
At her explanation, the expressions of Darkseid, Daoist Ziyun, and even Thanos changed.
She had said little, but they immediately understood. It was a causal attack.
At their level, causal attacks were no longer so mysterious.
