In a way to make this interesting, I'm going to put up Battler's "alternate self," the one created from all of the culprit theories regarding him.
Name: Battler Ushiromiya
Nickname: Black Battler
Age: ??? (probably the same as the real Battler, 18)
Gender: Male
Abilities: Just like the real Battler, he has the combat skills and is abnormally stronger than the real Battler. Being only an existence created from culprit theories, B. Battler does not have the access to the Red Truth, Blue Truth, or Golden Truth. Instead, he seems to have an alternative that appears like a "Black Truth," though it's not confirmed on what the effects of this are.
Species: Embodiment / Human
Appearance:
From: Umineko no Naku Koro ni Chiru
Other: Even if he is an entity that is created from the Battler culprit theories, B. Battler regards himself and the real Battler Ushiromiya as "different people." It is conveyed that his existence was created by Bernkastel and Erika.
