If you haven't seen Ant-Man or The Asdf Movie this joke is lost on you. Spoiler in Notes and Credits (incase you haven't seen Ant-Man or asdfmovie)
scroll to bottom I meant all the way at the bottom Basically Ant-Man is fighting Yellowjacket in his daughters bedroom and Ant-Man accidently makes a toy Thomas the Tank Engine big. The guy in the top left corner is the I Like Trains Kid. Whenever he says I Like Trains a train will come out of nowhere and kill everyone!
