No. 156 is also one of the three Higes that stayed with Mujoe during Mechadoc's coup d'État. No. 156 also participated in the B-1 grand prix, winning against Top Bomber and Seagull Bomber. Although, Top Bomber drove himself off the ring when No. 156's fake Bomberman antenna fell off, and Seagull Bomber was "absent" during his match against No. 156.
No. 156 also appears in the final episode of the series.
