Powerless, friendless and far from home, can he convince an alien stranger that he's worth saving? Plus, with Infinity Wars on the horizon, Strange and a new companion face the Super-Skrull, wielder of the Time Stone! But where will Strange head next on his interplanetary power trip? And what shocking surprise is waiting for him back on Earth?
