If you watch WW84, definitely go for HBO Max for safety reasons
Some of the stuff people have pointed out to me
-Cloud (well this one I saw myself too)
-An Attack on Titan Character
-Greg Universe (Which presumably means Steven's getting his own fight)
-Ryuko Matoi
-What could be either the Shredder or Doctor Doom
-Luke Skywalker and Yoda in the same scene
