In response to the Avengers heading off to space during Infinity to recruit help to take down the Builders, Luke Cage will be forming a new team of Assemblers to take on the threat that is the Mad Titan, Thanos.
Marvel released the following Infinity "Mighty" teaser featuring a gold fist, which is most likely Iron Fist, and using the Marvel AR app revealed the involvement of Luke Cage.
Maybe the return of The Mighty Avengers?
We see five more will be joining the team.
Tom Brevoort is unlocked and offers:
Welcome to our first Mighty teaser, the first teaser about this new project coming up, that we'll be telling you about all week. During his tenure with the New Avengers, Luke Cage became the moral center of the team. While he's now retired from being an active Avenger because of the need to raise his daughter in a safer environment, the call to arms, and the catastrophe that is Infinity forces him to get back up off the bench and pull together a bunch of other characters to be the Avengers when no one else can. Luke's the one character with the gravitas and the wherewithal to make this happen.
