Breastforce
No, this isn't a typo. Breastforce is a group of Destrons who have animal-body partners
that transform into their breastplate armor, and also into weapons. The members are
Leozack (jet/robot, leader), Hellbat (jet/robot), Drillhorn (drill/robot),
Gaihawk (jet/robot), Killbison (anti-aircraft tank/robot), and Jargua/Jaguar
(car with missile launchers/robot). They combine to form the gestalt Liokaiser.
Among Liokaiser's abilities is the ability to fight while invisible.
Deathsaurus (dragon/robot) had two breastplate partners
(Eaglebreast and Tigerbreast), which made him physically a
Breastforcer. However, he is not generally considered a true member
of Breastforce, since he never participated in Breastforce
activities, and could not combine with Liokaiser.
