Masquerade battles Dan. though he ends up losing. After the battle is over, Masquerade takes off his mask, and the Brawlers find out he is Alice. Suddenly, Hal-G appears (as a holographic projection) and explains how he and Alice, became their alter-egos after being exposed to the negative energy from the Silent Core once Naga tried getting it. After finding out that she is Masquerade, Alice feels guilty for everything she has done and so she goes with Hal-G and they disappear together. (In the Japanese version, Alice goes by herself as she says "Goodbye, grandfather." unlike her dub speech "Alright grandfather, I'm ready.")
