And I'd like to go on record as saying this is the dumbest idea in the history of Gotham City. 
The Superheavy Batsuit, nicknamed Rookie, was the mecha Batsuit used by Jim Gordon during his time as Batman.
History
The suit was created by Daryl Gutierrez while he was working for Powers Internationals for Jim Gordon as he was supposed to take up the mantle of Batman.
Gordon used the suit thoughout his period as Batman until he retired once again to civilian life.
After Gordon was corrupted by the Batman Who Laughs and turned into The Commissioner he used Rookie to attack Superman and Batman but it was ultimately destroyed by the Man of Steel.[1]
A new version of Rookie was worn by Mister Bloom and used to rip through the ranks of Task Force Z until it was destroyed by Gotham.[2]
