Dr. Seth Brundle - later known as Brundlefly - was a scientist who had his genetic structure altered as a result of a teleportation accident. When he unwittingly entered a telepod along with a housefly, the two organisms got fused together at a genetic level. His gradual transformation into a repulsive man/fly hybrid was accompanied by increasing mental instability.
History[]
When Brundle emerged from the telepod, he appeared normal and had no reason to suspect that his DNA was now 50% fly. The initial signs of his genetic disorganization were increased physical strength, enhanced reflexes, and agitation, as well as an intense craving for sugar and the appearance of coarse, hairy bristles on his back. As time passed, Brundle's skin began to decay. He also developed the ability to cling to walls and ceilings, and to regurgitate a corrosive digestive enzyme onto food before consuming it. Later, he began to lose his hair, followed by his ears, fingernails, and teeth.
Referring to himself as "Brundlefly", Brundle determined that the only way to regain his humanity would be to merge with another human being in the telepod, as the resulting entity would be 75% human and only 25% fly. He abducted his lover, Veronica Quaife, forced her into a telepod, and climbed into a secondary unit. By this point, Brundlefly's metamorphosis was nearly complete and his remaining skin and flesh fell away, revealing a bipedal, insectoid figure. Despite its lack of wings and exoskeleton, the final stage of Brundlefly was more insect than man, as he possessed an elongated head, large black eyes, slender limbs with extra joints, and a segmented body.
Fortunately, Quaife ultimately got rescued by magazine publisher (and ex-lover) Stathis Borans, who severed the power cable of her telepod with a shotgun blast. Enraged, Brundlefly ruptured its own telepod at the crucial moment and began to step out, just as the fusion program commenced. As a result, the creature was fused with the shattered device. It emerged from the third, "receiving" pod as a thoroughly corrupted being. The hapless creature reached for the shotgun, pleading to be killed for mercy's sake, a plea a heartbroken Veronica answered.
