KGBeast

KGBeast appeared briefly in the animated film, Batman: Assault on Arkham and was voiced by Nolan North. He was briefly a member of the Suicide Squad right before the mission to assassinate the Riddler.

Arkham Unhinged Incident
Batman mentioned that he was hunting KGBeast in Russia when he discovered that Harley Quinn had recruited the Abramovici Twins.

Assault on Arkham Incident
When Amanda Waller called in the Suicide Squad for another mission, KGBeast was deployed from a cargo plane. He launched the sidecar of his motorcycle at a presumably American-owned base and detonated it, only to end up captured by the Military. After being inducted into the Suicide Squad, KGBeast believed that Amanda Waller was lying when she informed the Squad that there were powerful nanotech explosives that were implanted in their necks. Waller let KGBeast have the option to leave to test if she was actually lying, so he took that option. As soon as KGBeast stepped out of the room, his explosive gave warning beeps, then blew his head off. He served as the example to the other Squad members as to what would happen to them if they disobeyed orders.
