While Leozack (レオザック, re-o-za-kku) is the commander of the elite Decepticon Breastforce and Deathsaurus' most trusted warrior...he really can't be trusted. Leozack is a conniving so-and-so, determined to rise to the highest rank of Decepticon power. All that stands in his way is Deathsaurus. Which, to Leozack's regret, is a hell of a lot to be in the way. His breastplate, the Lionbreast, can detach and transform into a lion-like attack partner or a handgun.
Leozack can combine with his fellow Breastforce warriors to form Liokaiser.
Japanese cartoon continuity
- Voice actor: Keiichi Nanba (Japan)
Leozack grew to loath Deathsaurus habit of not getting his hands dirty and made schemes to overthrow him. His schemes either failed because of his own incompetence or because of Hellbat's counter-scheming. Deathsaurus was aware of Leozack's desire to overthrow (Leozack didn't practically announce his intent his leader right away, but he still wasn't very good at keeping his intent a secret), but mostly overlooked, since if Leozack's incompetence caused his schemes to fail then Deathsaurus likely didn't see as a threat (who would?), and Deathsaurus couldn't replace him. Leozack's loyalty was questioned by Deathsaurus at one point, who gave him two choices: swear his eternal allegiance to the Emperor of Destruction or die. Leozack still keeps his head on his shoulders to this day. It does, however, get vaporized when Liokaiser was blasted by Deathsaurus' fortress cannon.
While Leozack was off fighting Autobots, his sister Lyzack watched after the Decepticon families and tried not to cry too much.

Wings Of Honor
- Accessories: Sword, rifle, 2 missiles
- Leozack is a blueish silver and blue redeco of Energon Starscream mold. He transforms into a jet fighter loosely based upon the F/A-22 Raptor. The toy also features numerous spots of sculpted battle damage and asymmetrical plastic-color layouts. He comes with two very large accessories, a sword and a non-firing blaster, which can combine to form a really larger sword and/or non-firing blaster. In jet mode he has two wing-mounted spring-loaded missile launchers, which can flip up over his robot-mode shoulders for "Hyper Mode". His wings and sword/guns (and cockpit) are now blue, with his cockpit having been painted yellow. His wings have white paint apps and his head is painted blue with red for the eyes and vents. He was available only at Botcon 2009 to attendees. Attendees who went to package pickup could receive two additional Leozacks upon purchase of the Botcon 2005 Descent Into Evil giftset.
- Leozack is the only Breastforce member that was not reissued in China in 1995 by Hasbro International.
- Leozack can hide in sand like Scrooge McDuck swimming through money.
- Leozack's speech pattern is very stereotypical of anime. His character card furthers this, by stating that he has to use voice commands to transform and use various attacks.
- As of Botcon 2009, Leozack is a seeker (or at least once was a seeker).
