The Breastforce (tee hee!) are Deathsaurus's elite troopers, and next to the Dinoforce, his only troopers. The Breastforce comprises some of the most vile Decepticons imaginable, from murderous back-stabbers to incarcerated convicts. Each one has a Breast Animal, a partner formed from their titular breastplate armor that can act as an autonomous fighting unit or hand-held blaster. Don't let the name fool you, the Breastforce are nothing to laugh at.
The Breastforce consist of:
- Deathsaurus, the Emperor of Destruction and dragon-thing.
- Leozack, Deathsaurus' second-in-command and Grumman F-14D "Tomcat" fighter jet.
- Drillhorn, the tunnelling machine.
- Gaihawk, the MAPO MiG-29 "Fulcrum" fighter jet.
- Hellbat, the Dassault Rafale fighter jet.
- Jarugar, the Baja buggy.
- Killbison, the Gepard anti-aircraft tank.
- Deathcobra, the Mi-24 Hind assault helicopter.
Leozack, Drillhorn, Gaihawk, Hellbat, Jarugar and Killbison can combine to form the warrior Liokaiser. Among Liokaiser's abilities is the ability to fight while invisible. (Deathcobra had the capability, but was never able to utilize it.)
Unlike the rest of the Decepticon sub-groups, not all of the Breastforce was introduced at once. At first, it was just Leozack. Then Drillhorn, Jarugar and Killbison came in, then Hellbat, then they broke Gaihawk out of prison. Although they were able to handle most of the Autobots, despite their teamwork, they could never defeat Star Saber. They almost managed it when they first formed Liokaiser. Only God Ginrai's arrival saved Star Saber, but even the two of them were only barely able to stop Liokaiser. Liokaiser remained a huge threat to Autobots, but he eventually met his match with Victory Saber. At the end of series, when Star Saber and Victory Leo were attacking Deathsaurus's space fortress, Liokaiser appeared to fight them in space. Victory Leo took on Liokaiser and killed him by throwing him into the main cannon of the fortress.
