The Atom, DC s shrinking scientist, is coming to Injustice 2 this month. It s Ryan Choi, the character created by Grant Morrison, rather than the probably better known Ray Palmer version. That version is currently being played by Superman actor Brandon Routh on Legends of Tomorrow, a show that I love, despite knowing it’s bad for my health. Becoming really tiny never sounds like a great superpower, but as the trailer below shows, it s actually the best power.
