The Gasman is eight years old. He earned his name from the fact that he frequently passes gas, although he is often called Gazzy, Gazzer, or Gasser instead. He also has the ability to mimic any sound or voice, an ability which he uses to play pranks. In the fourth book The Final Warning he gets the ability to release a gas that is yellow greenish.

The Gasman is a blond-haired kid with blue eyes, and is tall for his age like the rest of the flock. His wing color is a brown with white spots but wing size is unknown.

The Gasman and Iggy are best friends, and often work together to build explosives, pull pranks, or do tasks for the Flock. Gasman has assumed the names of Captain Terror (incorrectly spelled as Captin Teror when he was asked to spell it) when he was interrogated, and Zephyr, which is the name of the Roman god of the west wind. Max also called him "Jason" at Disney to cover up the fact Total could talk. His number at The School was F28246eff

He finds a photo of his mother, and with a high-tech image scanner, he revels that the paper on the desk is a check for $10,000.

The Gasman is the biological older brother of Angel and they are the only members of the Flock who are actually related. Gazzy is constantly throwing his voice, and in the Second book, Max suspects he has thrown his voice to make it seem as if Total is talking, as well as in the first book when he assumes Iggy's voice to make Max mad. He can also copy the voice of any person, opening the possibility that he has magpie DNA. Another one of his super powers is the ability to pass gas at his own will.

He is revealed to be afraid of spiders
