KSI Boss is a KSI Prototype and the second largest of them all, and he is even taller then Galvatron. He was manufactured by KSI, originally intended as one of their military prototypes. But like the other prototypes, he was taken over by Galvatron and turned into a Decepticon.

KSI Boss is one of the deadliest prototypes in the film. He can be seen, but rarely. When Galvatron is infecting the prototypes, a KSI Boss prototype can be seen standing behind Stinger. When Hound fires at the prototypes from on top of a building, a KSI Boss can be seen fleeing from the incoming missiles.
