Boom

Boom is a Decepticon who appears in the IDW portion of the Generation 1 continuity family.

Boom shares a close link with his brother Sonic. This is because they poses a Branched Spark, meaning they could literally die if they are apart to long.

Together, he and his brother form "Sonic Boom", a devastatingly powerful Sound Bomb.

More Than Meets The Eye
Boom and his brother Sonic travel to the Autobot medical facility Delphi, seemingly on the run from the Decepticon Justice Devision.
