(Creatures on the Loose I#19 (fb) - BTS) - Chak was born a mutant Martian Wing-Man; while he had the same skin hue and wings as his fellows, he had a human face instead of the usual beak and horn. He was mocked and took to wearing a full helmet to imitate his fellow Wing-Men and hide his human features. But his people still made him an outcast.

(Creatures on the Loose I#17/1 (fb) - BTS) - Chak's lonely voyages took him to the icy wastelands of the spider-like Noltoi, who captured him and tied him up as an offering to the giant god Phra.

(Creatures on the Loose I#17/1) - The time-lost Earthman Gullivar Jones was also hauled to the altar as an offering and trussed up next to Chak, who warned Jones of their fate, just as the giant creature Phra surfaced to claim his offerings.

(Creatures on the Loose I#18/1) - Phra ripped Chak and Jones from the altar and took them underwater to his hidden lair. While Phra slumbered nearby, Jones used his newfound strength to  free himself and Chak, who revealed his mutant Wing-Men nature and human features. The duo found a video database that summarized Martian history: the golden-hued Hither People were once technologically advanced, but repeated cataclysms caused evacuation from cities; the power-hungry Technics Guild rose to safe-keep some scientific knowledge, but a Martian diaspora led to the evolution of eight additional races in a ravaged landscape. 

    Phra suddenly awakened and lunged at the two. Chak, who no longer acknowledged Phra as a god, and Jones fought back, toppling the giant, but this triggered fires amongst the old machinery. Chak and Jones fled by jumping into the water; Phra's lair exploded, pushing Jones and Chak to the outside surface, and Phra failed to escape. The two emerged amidst a graveyard of dead bodies entombed in ice.

(Creatures on the Loose I#19/1) - Amongst the ice-bound Martian corpses, the injured Chak and Jones found a cavern and lit a fire to keep warm, but strange sounds troubled them. Chak told of his history just as the sounds were revealed to be a massive horde of Parth (small, fanged creatures). Using abandoned weapons, the two cleared the Parth out of their cave, but were left exhausted. Later, feeling quickly healed, Jones realized his amulet held special healing properties and let Chak hold it to heal his injuries. But with the amulet, Chak saw the otherwise invisible Ra-Kar, a savage creature intent on killing them. Jones took the amulet and sword to fight the creature, but was distracted by the amulet's vision of his love Heru in danger. Ra-Kar used the opportunity to knock down the two.

(Creatures on the Loose I#20/1) - Chak helped Jones recover, and they coordinated a counter-attack that saw Ra-Kar kicked over a deep cliff face. Chak and Jones slowly climbed down the icy mountain, taking warmer clothes, food and weapons left for the spirits of the dead. Chak taught Jones of local edible fruits. They encountered and fought an encampment of Lizardmen. Continuing their descent, Chak told Jones that the star of Jones' home was considered lifeless by Martian scientists, reminding the Earthman of how far back in time he had been cast. But a roving patrol of Wing-Men captured the two and brought them to the camp of nefarious Lizardmen headed by Ar-Hap, keen for revenge against Jones. Chak was suspended in a cage while Jones was sent to a duel.

(Creatures on the Loose I#21/1) - Jones soon escaped and freed Chak, who permanently abandoned his beaked helmet. Fleeing, the newly-in-command Lizardman Jen-In threatened his captive Heru, so Chak disarmed him, then Jones killed him with a single powerful punch. Heru pledged her love for Jones. Meanwhile, Ar-Hap woke and charged his troops at the trio, who bested many foes. Soon Wing-Men also arrived and Jones sent Heru away with Chak for safety. The Wing-Men's simmering feud with the Lizardmen erupted into savage battle with the Wing-Men as victors. While the Wing-Men promised Jones their friendship, they still refused Chak. Jones soon rejoined Chak and Heru, and recognized hazards lay ahead, but believed that peace and love were worth fighting for.

(Monsters Unleashed I#4/5) - Keen to find a way home to Earth, Jones traveled with Chak and Heru through the desert to the ancient city of Seth to challenge the Technics Guild for information. Chak resolved to stay with Jones in the hope of eventually freeing his people. However, they had been shadowed by a Noltoi outcast, which had been exiled due to physical and mental differences, and sought the three as companions. Protective of Heru and hateful of the Noltoi, Jones and Chak attacked. Jones killed the Noltoi outcast, discovering the telepathic outcast's peaceful motives too late. All three were saddened and learned not to act so brashly in the future.

(Monsters Unleashed I#8/5) - Approaching Seth, the trio saw a giant Bloodbeast hybrid attacking the local Hither People and killed it. The Hither People were initially passive in response, but seeing their outcast princess, they became abusive. Chak discovered a tag showing the hybrid beast belonged to the Technics Guild. The threesome pushed past to challenge the owners, but the Guild's defenses kicked in, first with piercing sound that disoriented Chak, followed by winged humanoid slug hybrids armed with swords. The trio forced the hybrids' retreat, but new Technics appeared and easily overpowered the trio with sleeping gas. The trio were manacled and hauled for trial, and woke to hear the death sentence pronounced. The Technics' leader revealed his face, which was deformed from radiation, and unleashed a giant, tentacled cyborg monster dubbed Firstborn to kill them. Jones used his augmented strength to break his chains, then freed Heru and Chak. Jones killed the creature and berated the Technics for wasting scientific opportunities on genetic experiments. Realizing the Technics Guild could not help them, the trio strode off.
