The incinerator war droid was a battle droid used by the Galactic Empire around the beginning of the Galactic Civil War.
This droid stood several meters tall, and was armed with a flamethrower and tibanna gas tank along with a large blast shield. The droids were an advancement of the carbonite war droid, but they were developed to house a flamethrower in their "arm" instead of a carbonite projector.
By 1 BBY, the war droids had been developed. The project held the record for most industrial accidents and most casualties. The defector Captain Kamer Suu spoke about them.
the clone of Galen Marek had encountered several incinerator war droids on Kamino. Some of these droids also joined the invading Imperial forces on the Nebulon-B Frigate Salvation above Kamino, some of which also being used to fry the communications equipment onboard the Salvation before the clone destroyed them in an attempt to re-establish the communications with the Rebellion.
Incinerator war droids first appeared in the 2010 video game Star Wars: The Force Unleashed II.
