We got a glimpse of Injustice 2's Atom last October, which was oddly before NetherRealm finished releasing all the fighters from Fighter Pack 2. Either way, the incredible shrinking physicist will be available for purchase on December 12.
It's the Ryan Choi version of the hero is being featured and it looks like his shrinking and growing abilities are being integrated far better than Atom fans could have hoped for. He can shrink to dodge attacks, grow at the end of his finisher and even enter people's bodies for an "inside attack" as part of a grab maneuver.
The Atom will be part of Fighter Pack 3, which will include Enchantress and the Teenage Mutant Ninja Turtles. You can take a look at the trailer below for a more thorough look at some of his weird and wonderful tricks.
