Some characters from Galaxy Trio, including the three main characters, appeared in the Cartoon Network/Adult Swim TV series Harvey Birdman, Attorney at Law.


The Galaxy Trio is a group of interplanetary law enforcers who battles criminals throughout the cosmos. The group consists of Vapor Man, who can change into any type of vapor; Gravity Girl, who can control gravitational forces; and Meteor Man, who can increase all or part of his body to impossible heights, gaining super strength in the process. They patrol space in their cruiser Condor One maintaining order and fighting evildoers in the name of the Galactic Patrol law enforcement agency. The ship was equipped with a "displacer" very similar to the transporter device on Star Trek, which was a contemporary show.


Vapor Man

Vapor Man (voiced by Don Messick) has the ability to transform part or all of his body into gaseous form (a power shared by at least some residents of his home planet of Vaporus), enabling him to fly, escape from physical bonds, and squeeze through very small spaces, as well as producing various forms of "vapor" (such as "freeze vapor") from his hands.

Meteor Man

Meteor Man (voiced by Ted Cassidy) is a native of the planet Meteorus. Meteor Man is distinguished by his ability to increase or decrease the size of any part of his body. He gains superhuman strength in any limb that he chooses to enlarge.

Gravity Girl

Gravity Girl (voiced by Virginia Eiler) has the ability to bend the laws of gravity to her will, allowing her to fly and lift very heavy objects with her mind. The daughter of the king of the planet Gravitas, she left her luxurious home and life of privilege at an early age to fight crime with the Galactic Patrol and was subsequently assigned to the Galaxy Trio team, with whom she has served ever since.


Chief is a man referred to only as "Chief", he is a recurring character in Galaxy Trio. He fulfills a similar role to that of Falcon 7 in Birdman.
