Lockheed makes sporadic minor appearances in X-Men related animated television series and made his live-action debut in the 2020 film The New Mutants.

Lockheed was created by writer Chris Claremont and artist Paul Smith and first appeared in Uncanny X-Men #166 (February 1983).

The story recasts the X-Men, including the recently deceased Jean Grey, in the roles of fairy tale characters.

Lockheed had been celebrated by his people as a brave fighter and hero against the Brood, but had demonstrated individual attitudes and wishes which were realized only when he encountered the X-Men.

[3] She, as well as Professor X and her teammates, are unaware of his presence in the X-Mansion until he again saves Kitty's life from a nest of alien Sidrian hunter hatchlings.

To a lesser degree, Lockheed also bonds with Illyana Rasputin,[volume & issue needed] who, after being abducted into the dimension of Limbo (also known as Otherplace) by the sorcerer Belasco, had aged into a teenager, manifested her own mutant powers, and been installed as Kitty's roommate.

In the companion series Spider-Man and the Secret Wars, it is shown that Lockheed spent some time patrolling Denver, Colorado, which had been taken to Battleworld as well, protecting its citizens from alien attack.

Near the end of the Caper, Lockheed and the team believe Kitty to be lost in the dimensions; in reality she had been transported home far earlier than the rest of the group.

While healing from injuries gained from fighting Doctor Doom,[11] his astral form is apprehended by the Flock and made to stand trial for treason.

After managing to explain his motives and saving his fellows from a piloting accident, he is officially exiled from his race, but on amicable terms.

At one point, jealous of Lockheed's relationship with Kitty, they invade the tunnels under Muir Island and hold him prisoner for some time.

[volume & issue needed] Lockheed develops a severe distaste for the secret agent Pete Wisdom, Kitty's love interest.

This created problems because many of the students found it hard to actually believe in a living, miniature dragon; the mutant Wither ended up endangering Lockheed with his organic-destruction powers.

A brochure included at the end of Wolverine and the X-Men #1 states that he teaches a class entitled "Knowing Your Alien Races, And How To Kill Them".

In another instance, he expresses feelings of guilt over acting as a mole for S.W.O.R.D, stating that he had already "betrayed too many friends and allies in the past".

He has purple skin, sharp claws and teeth, two small, curved horns protruding from the back of his head, and wings that enable him to fly.

He can breathe extremely intense fire and is a surprisingly formidable combatant for his size, having once destroyed a nest of Sidri hatchlings and at another time bested a fully armored medieval knight-in-training.

When he first appeared as drawn by Paul Smith, he was largely quadrupedal, with monochromatic red eyes, a triangular head, and dog-like intelligence.

By the time of his appearances in Excalibur as drawn by Alan Davis, he possesses a more anthropomorphic design with an oblong head, black eyes, and a longer jaw Lockheed is capable of speech, but initially did not display the ability to do so.
