KSI Boss is a KSI Prototype and the second largest of them all, and he is even taller than 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.


Age of Extinction film

KSI Boss's first appearance. He can be seen standing behind Stinger.

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, one of them can be seen fleeing from the incoming missiles.

A KSI Boss being killed by Hound's grenade

The most recognizable appearance is when Hound chucks a grenade at a small building, two of them can be seen flipping cars towards Bumblebee, until they are both destroyed by the explosion.

Two KSI Boss's being smashed by Scorn

When The Dinobots charge downtown, two of them can be seen firing at Scorn. However, Scorn ends up chomping one of them in half.

When Optimus arrives with the Dinobots, Grimlock breaths fire over a couple of KSI Boss's on a bridge, causing one of them to fall off in flames and crash below.

When Optimus jumps off of Grimlock he chops one of them in half. As the Prototypes are fleeing, Slug can be seen trampling one.
