Dream Girl and Psylocke merge to form Dreamlocke. Dresses like Psylocke in her ninja-kini, only it is the metallic silver-white of Dream Girl's outfit, and her long, straight hair is white with a purple tinge to it. She kicks ass and unleashes 'the focused totality of her precognitive powers' with her Cassandra Coil, which causes anyone hit by it to be overwhelmed with distracting visions of all the many possible ways she's about to kick their ass! She smacks you once, but you get to experience a dozen beatings in that single moment!
In his 'Penance' phase, BB was called Murderball. Thankfully it was a one-arc thing.
