Liokaiser (ライオカイザー Raiokaizā) is the combined form of the Breastforce, an elite combat team consisting of land and air assault vehicles who hail from the Death Zone. He is powerful, cruel, merciless, and—unlike pretty much every other combiner—intelligent to boot. This ruthless killing machine is an expert in melee combat and possesses the power of invisibility. He's fought against Star Saber, Road Caesar, Landcross, and Galaxy Shuttle, promptly beating the stuffing out of each.
