A new teaser image has been released by Marvel, with the phrase "Injustice, Like Lightning." The image came as part of an email with the subject line of "From the Ashes of Avengers: Standoff..."
"Justice, Like Lightning" was the slogan for the original Thunderbolts team by Kurt Busiek and Mark Bagley, and although the blue individual is unknown, some of the other silhoettes look like they could be the Fixer and Mach 5. And if you recall, team founder Citizen V was shown as part of the original "All-New All-Different Marvel" announcement image but has yet to show up.
Marvel's April 2016 solicitations mentioned "lost heroes" would be returning in Avengers Standoff: Assault on Pleasant Hill Omega #1. Could the Thunderbolts be those "lost heroes"?
