Re: Countdown to the Age of Ultron
You skipped over an Ultron story in issues 66-68. It features the introduction of adamantium.
John Buscema in Avengers 75 established the Scarlet Witch's default appearance. Her hair in previous Avengers issues had been black, but is now brown. Her leotard is now strapless. The ridges in her boots are gone, and they are flat against her calves. Artists would change Wanda's costume over the years, but eventually Wanda would always come back to the default look established here.
Wanda's amnesia is gone, but she still doesn't have her powers back.
