The Big Chill

Using his new ice powers, Mr. Freeze steals the most rarest and valuable diamonds all over Gotham. When him and Batman first cross paths, he tells the Bat he's the reason why he's a cryogenic monster. It's because of a much earlier chase between them, which led to a cryogenics lab. He will stop at nothing to make Gotham his own personal domain, unless the Batman can think of a way to stop this menace.
