Black Battler

Note: This page contains spoilers. Battler Ushiromiya at one point, desperate, countered Erika 's theory with a counter-theory of himself being the culprit, and when Bernkastel created her game, Black Battler was a game piece create by her desire.

Black Truth of Death
He appears to be just Battler in a dark suit

In Bernkastel's game

This means that Black Battler was never truly "real".

Season 3
When Chris-chan tried to use The Focusing Stone 's power to bring The Merge, all he did was merely merge himself with his magination of Sonichu, a perfect Mary Sue and the hero of his imaginary world(An abstraction of himself), becoming the Abomination. From that, we can assume that when Battler used The Focusing Stone to fix the Time Merge, it somehow saw Battler's culprit theories in his head and assumed it was the closest to Battler's perception of itself, merging Black Battler into him.

For the first time, Black Battler is "real" outside the game, and now he was ecstatic about it. And he would not let anyone take that from him, even if he has to kill.

Upon returning, he locked up on Battler's office, probably scheming his plans, when Kinzo Ushiromiya came to confront him, however, Battler didn't open the door until when he had lost hope and was leaving, but when Kinzo went in in, he shot him dead.
