Best Character Development
What are some of the best character developments and the worst negation of that development to re-establish status-quo in comics IYO? I vote Baron Zemo. He went through a fantastic character development from a villain of the week to a complex, multi-layered anti-hero who wanted to save the world by his own methods. Then Brubaker negated all that and sweeped that under the rug. What are some other examples like this?
