"Megatron's Loyal Decepticon Hound."
"All hail Megatron!" - Blackout
The massive Blackout has been described as the "hound" of Megatron. In better days he was always to be found looming powerful and silent behind his leader's right shoulder. When given a target he hunts it down with fierce determination.
During the search for the All-Spark, Blackout was not happy with the progress Starscream was making towards finding the missing Decepticon leader. He suspected (quite rightly) that Starscream would prefer Megatron to stay lost.
Blackout was openly mutinous and willing challenge Starscream's leadership at any opportunity, not for his own sake, but to better serve his ultimate goal of finding his lost master.
Blackout has a sneaky side and uses his symbiotic companion Scorponok's small size to great advantage.
Sometimes he is also known as N.B.E. 23.
