Lyzack is the younger twin sister of the Decepticon Breastforce member Leozack. Though they're from the same assembly line, Lyzack was not built as a warrior, unlike her brother. Instead, Lyzack was designed to serve at home. This troubles Lyzack, who longs to be as skilled as her brother, and so the female Decepticon withdraws from those around her. Her meekness is misleading, though; given a sword, she is surprisingly deadly. She transforms into an F-14 Tomcat jet, same as her brother.
