According to his official profile, his mission is to find a missing friend, his mentor Ray Palmer a.k.a. the original Atom.
Armed with his quantum bio-belt and a prodigal knowledge of physics, players can utilize all of scientist Ryan Choi's subatomic powers to deliver justice against Superman's regime.
You can check out Atom in action, below. In addition to Leonardo and company, the new pack of fighters will give us the opportunity to control Enchantress and Atom.
Met Office upgrades snow warning to amber
There may be a light dusting of snow around the country, and it may stick in places in the north and northwest. Slight to moderate accumulations are possible with up to 3 cm in parts along with Icy stretches too.
I particularly like how Atom can shrink to avoid projectiles (at one point he shrinks down to a tiny size to avoid Joker's crowbar attack), and fly into the body of his opponent (Bane hits his own head to force Atom out). This character is going to be a nightmare to play against. Watch the trailer below... Fighter Pack 1 includes Red Hood, Starfire, and Sub-Zero, and Fighter Pack 2 features Black Manta, Raiden, and Hellboy.
When Atom is normal size, he employs the use of a variety of different scientific gadgets and chemicals for his attacks, causing him to look like he will be one of the most colorful and vibrant fighters of Injustice 2.
Atom due out on December 12.
