Journey through the MCU

You turn around to see if the rhinos are on your heels. At first, it seems like there is a massive creature right behind you....or maybe that's a bush. You don't want to stop and see clearly, in case it's as close as it appears. You keep staring at it as you run until you run into something....in the middle of a grassland??? When you had looked forward a couple seconds ago, you didn't see something. But this isn't just a tree or an animal or something, this is like an energy wall. The invisible wall zaps you fifteen feet from it and you hit the ground very hard. Your body is now burning up painfully and your back seems to be broken. Guess this is the end of the road for you...literally...and so soon after you started. Pity. Better luck next time.
