From what I know from the extra bits shown on Umineko Hane (extra arcs), B. Battler basically almost kills Ronove, one of Beatrice's strongest Furniture, without the need of Red Truth or Blue Truth, and happens to give off a "godly" aura due to the theories that created his existence being that strong.
A little bit of his personality is shown in one of the spin-off fighting games, and he's sadistically enjoying the experience of killing off the other characters (in his story mode at least). It would be interesting for B. Battler and Bob to meet, or even B. Battler meeting the real Battler.
