Boom Beagle is one of three explosive-expert Beagle Boys. His first appearance was in July, 1972, in the Beagle Boys story "Boom Beagle's Big Backfire" by Pete Alvarado, until being re-used in several Brazilian comic stories.
He wears earmuffs and usually drives a truck with big balloon tires. Instead of a prison number, his shirt spells BOOM.
- The character must not be confused with the other explosive experts Countdown Beagle or Boom Boom Beagle.
