Go-Baberu-Da

Go-Baberu-Da (ゴ･バベル･ダ)/Unidentified Life Form #45 (未確認生命体第４５号)/B12 (Ｂ群１２号): Baberu assumes the form of a man in his forties with a headband and black lips. When his turn came, he targeted underground centers, using his default Grapple Form (格闘体)'s natural strength and armed with a pair of brass knuckles to block all escape routes to ensure the police don't interfere in his game to kill 682 people within four plays. On the third day, Baberu battles Kuuga, defeating his Titan Form easily in Herculean Form (剛力体), armed with a war hammer, until Ichijo uses the Muscle-Relaxing Bullet (筋肉弛緩弾) to weaken the Gurongi as Kuuga takes him to the location to finish him with his aided Rising Beat Gouram.
