Bruce Wayne of Earth -32 is pretty similar initially. His parents die, and he sees the murderer, Joe Chill. His emotions leave him and are replaced by a cold void. A green lantern ring finds its way to him, and he uses its powers to find and kill Joe Chill. Now, Green Lantern rings don't usually allow the bearer to create a construct that kills, but Bruce forces his incredible willpower while flooding the ring with his cold emotionless void, breaking that one rule. After killing Jim Gordon for questioning his methods, the Green Lantern Corps comes after him. Then he up and murders them all! Wow.
Afterward, he enters the Green Lantern Power Battery by shedding his former identity and adopting a Batman type persona after the cave of bats under the manor. As his world is crumbling, The Batman Who Laughs offers he join the Dark Knights in subverting the Multiverse.
This isn't the first time by a longshot that Batman has had a power ring, but it is easily the evilest version! Change my mind! I like how they captured the figure. His skin is this dusky grey, he's got a mean sneer on his face, and his Green Lantern outfit really pops against the black underlayer. I added a slight black wash to most details to make things stand out more, as I'm finding more and more with these figures they are just missing a little something to make them more interesting. His accessory bats are neat, and his poseability works pretty well, though I wish he could look up more. Any flying character should have a lot more head flexibility.
