Batman Arkham: Court Of Owls - 10 Characters That MUST Appear

Brother Eye would effectively be one of the most interesting characters that could conventionally be placed into a Batman game. It'd be difficult - and would really make or break it - but the potential enormous payoff would definitely be more than worth it.

Brother Eye is the concrete proof that a classic Batman trait is that he often goes way too far. Brother Eye itself was constructed so the billionaire could keep track of the Justice League via some particularly sketchy surveillance. It's hacked into by villains on several occasions, and eventually made sentient during a scheme wherein Lex Luthor has control of it - highlighting that Batman' paranoia works against him as much as it works for him.

While Brother Eye may have to be saved for a time wherein more Justice League members have games, including the unusual robot would make for a really interesting look into some of Batman's less heroic choices.
