Comet, sometimes referred to as Comet the Super Horse, was Supergirl's pet horse who had Kryptonian powers and fought alongside his owner.


Comet's powers consisted of a smaller subset of those of Superman and Supergirl, including flight, super-strength,super-speed and Telepathy.

Pre Crisis History

He was originally a centaur in ancient Greece named Biron. The witch Circe gave him a potion to turn him fully human after he prevented an evil sorcerer poisoning her water, but by mistake made him fully horse instead due to the Sorcerer. Unable to reverse the spell, she instead gave him superpowers, including immortality. The Sorcerer asked his teacher to help him against Biron and they were able to imprison him on an asteroid in the constellation of Sagittarius, which he had been born under. However when Supergirl's rocket passed it broke the force field, enabling him to escape. Later, after meeting Supergirl, he went on a mission with her to another planet, where a magic spell was cast that turned him into a human, but only while a comet passes through the solar system he is in. As a human, he adopted the identity of "Bronco" Bill Starr, a rodeo trick-rider, whom Supergirl fell in love with.

Comet made sporadic appearances in comic stories through the 1960s, and even became a member of the Legion of Super-Pets, a group consisting of the aforementioned super-powered animals.

Other Versions

Pre-Crisis Comet appears in Supergirl: Cosmic Adventures in the 8th Grade. Supergirl from the 30th century gifts her younger self the horse to save the world in the past. He helps save a baffled Superman and Supergirl from Lex Luthor. When the younger Supergirl fades away due to her powers malfunctioning the horse is left with the Kara from the changed timeline, who admits she has no idea what to do with him.

Post Crisis History

Debut Supergirl #14 (October 1997
Created by Peter David
AKA Andrew Jones/Andrea Martinez
Affiliation The Stable
Abilities Super-speed, flight, ice wings, ice vision, psionic love manipulation

A very different Comet was introduced in Peter David's Supergirl #14 (October 1997). This version was originally introduced as a hero with flight and cold-generation powers. Comet's appearance was unclear, as when using his powers he was surrounded by an aura of cold that made him resemble an actual comet. Comet looked like a man with three fingers, horse-like legs, long white hair, and a star mark on his forehead. There was a lot of speculation about who Comet was, but it was revealed that Comet was Andrea Martinez, a bisexual stand-up comic, who like her friend Linda Danvers (who could turn into Supergirl), could shape-shift between her human and super-powered forms (however, Comet's change also involved changing gender, from the female Andrea to the male Comet).[1]

Soon, it was learned that Comet's male form was originally Andrew Jones, a (male) jockey, who had been trampled by horses and "rebuilt" by an organization called "The Stable" as a superhuman with equine DNA. He rebelled against the organization and began operating as a superhero. On one of his first missions he attempted to save a despairing Andrea Martinez (who had just come out to her parents, and been rejected) from an avalanche, but they both died. As with Matrix and Linda Danvers (who had merged into Supergirl, the Angel of Fire), this caused them to combine into one being: the Earth Angel of Love. Comet originally was in love with Supergirl, and since he was the Angel of Love, made her have feelings for him too, but she rejected him when she learned he was also a woman. This opened the door for the third Angel, Blithe, the Angel of Light, to use her powers to exploit Comet's heartbreak, and turn them against Supergirl. She enabled Comet to fully embrace their angel powers, transforming him/herself into a winged centaur.

Blithe deceived Comet into joining forces with the Carnivore (a powerful demonic creature who despised the Earth Angels, and sought their power). The Carnivore lost control, however, when Andrea abandoned her anger, learning that her mother had died, and had left a video apology for her actions. The three Earth Angels worked together to stop the Carnivore. Comet began a relationship with Blithe, since she loved both their forms (revealing that Blithe is bisexual).


Comet originally had the power of high-speed flight, and when he flew he left a freezing contrail behind him. Comet also generated a psionic aura which stimulated feelings of love in those around him. When he became an Angel of Love, he gained wings of ice, ice vision (blasts of subzero energy he released from his eyes), and a centaur-like form which gave him horse-like strength. Comet can shape-shift between his centaur form, and his female form of Andrea Martinez.
