Avengers (2023 series) #28

While the rest of the Avengers were thrown into a pocket dimension by Dormammu in One  World Under Doom #3, the injured Captain America (Sam Wilson) with Black Panther (returned from a separate adventure) were trapped in their base the orbiting Impossible City which had been taken over by some Masters Of Evil led by Mad Thinker. They defeated Dreadknight, Exterminatrix, Madcap and Mr Hyde, but Thinker combined their powers into a Super-Adaptoid which he's now using as armour. And he's now coming for them.
