Super Beast Combination Live Boxer (超獣合身 ライブボクサーChōjū Gasshin Raibu Bokusā):
Liveman's second robot, built by Black Bison and Green Sai based on blueprints left to them by their slain siblings. Comprised of Bison Liner and Sai Fire when the command "Fusion! Boxer Dimension!" (合体! ボクサーディメンション! Gattai! Bokusā Dimenshon!) is given, Live Boxer specializes in boxing and kick-boxing attacks. Its special attack is the Piston Punch (ピストンパンチ Pisuton Panchi), and its finishing attack to destroy giant Brain Beasts is the Miracle Big Blow (ミラクルビッグブロー Mirakuru Biggu Burō).
