The West Coast Avengers, Vol. 2 #42 (Cvr A) (1988)

Vision Quest, One of Our Androids is Missing!
Wanda wakes up alone. Before she can locate her husband, the compound is attacked by Ultron. Or, at least, that's the way it seems; it's a fake Ultron, sent as a distraction while all traces of the Vision are wiped out from every computer on the planet, and it looks like an inside job.
