Retcons!
With the recent drops, a few things had to be rewritten to compensate for their absence. And lo, come the character retcons. These are the ones the mods know of; please feel free to use this post to discuss any significant changes related to recent character drops.
» Marvel Kaplan became Justice II instead, mimicking Owen's powerset through the use of a power suit. As Justice, Marvel led the Avengers for almost a year before being exposed in May 2010. He avoided incarceration for his crime by the skin of his teeth (and more than a little legal nepotism).
» Jes Rogers took over after Marvel was booted and led the Avengers under the name Liberty. During her stint as Liberty, she wore a version of the Captain America suit and held the vibranium SHIELD once Owen passed it on to her. She was active from June 2010 to January 2013, when she passed the Avengers over to a new leader and returned to SHIELD full time as Warbird. She's still a registered superhero, but her professional attachment to SHIELD frees her from some of the position's obligations (re:zoning, alerts, etc.) because of that commitment.
