Not long after, and warning NOT to unleash Giant Robo, he and BF enter into negotiations with the Japanese Government playing an audio of Guillotine for surrender in exchange for the lived of the Hostages. After asking for a 24 hours consideration from the representatives, Unicorn plants a tracker on his car, but the villains get wise to it as they overheard the plans with a hearing device in the recorded.

In the midst of this, one the BF driver begs Over to spare his Brother, who was among the 60,000 people kidnapped by Sparki, been the only family he has left, with the villain holding his choice to see his performance.

There after, he has a Cat and Mouse game with Unicorn, which leads into a box canyon, and hearing Over's voice warns they have until Noon of the day after to surrender or Sparki would be unleashed onto Tokyo. Knowing he may still be near by, they search the area and reach a Cemetery where he is spotted and the agents converge. Over jumps on one of the agents, then tries to do the same with Daisaku and Minami, though the boy shoots him; wounded and surrounded, Dr. Over still manages to pull one of his tricks and escapes.
