Avengers (1998) #22: This Evil Triumphant

Issue Summary

The Slorenia strikeforce team of Avengers (Black Panther, Captain America, Thor, and Firestar) are being swarmed by hundreds of Ultron robots, and are close to being overwhelmed. Jarvis notices Justice is gone from Avengers Mansion. Ultron is nearly done making the brain imprints of his 'family', as the Vision gets free as well as Eric Williams. He frees the other captives as the strikeforce crashes through the door. They swarm Ultron as Justice arrives and gives them Vibranium, which can defeat Ultron. The team regroups as Alkhema is revealed to have all the imprinted brain patterns.
