- Auggie Smith discovered the QUC device with the alien in Peacemaker Season 2, Episode 4, after he killed the creature.
- As of now, it's unclear which species this alien belongs to in the DCU.
- The introduction of such extraterrestrials could signal a major development in the future of the DCU.
James Gunn has never been shy about sprinkling bizarre deep teases into the DCU, but Peacemaker Season 2 Episode 4 gave us one of the strangest ones yet. The opening takes us 35 years back, showing young Auggie Smith stumbling upon an alien in the woods and shooting him. The alien was carrying somewhat of a briefcase, which turned out to be the doorway device that becomes central to the season. So, now the question is, who is this alien we see in Peacemaker Season 2 Episode 4? Let’s find out.
What Is the Doorway in Peacemaker?
The flashback reframes Auggie Smith’s “invention.” He didn’t engineer the mysterious doorway; he found it and called it the Quantum Unfolding Chamber, allowing him access to multiple dimensions wherever the briefcase-like device was set up. This single moment explains why the Smith family had access to such tech, and it roots the entire season in an otherworldly origin.
What Do We Know About the Alien in Peacemaker Season 2 Episode 4

The alien we see in Peacemaker Season 2 Episode 4 carries a humanoid frame, which certainly sets it apart from the Butterflies we have seen in Season 1. Moreover, the physical form of the said alien does not match any other species we have seen on screen so far in both animated and live-action DCU projects. So, with such little information and insight, it’s a bit difficult to say who exactly this alien was in Peacemaker Season 2 episode 4.
What Do the Theories Say?
Fans have been quick to connect the dots, and three main theories have emerged. The first is that the alien might have been a Coluan, part of Brainiac’s species. With Brainiac rumored for the DCU, the idea of a scout crash-landing with advanced tech makes sense.
Others believe the alien may be linked to the Guardians of the Universe from the planet of Oa, perhaps one of their failed or forgotten creations, which would explain the Lantern-like qualities of the QUC doorway technology.
Then there’s the possibility that Gunn simply introduced an entirely original species to expand the DCU’s cosmic canvas. Given his track record with creating weird and memorable characters, this wouldn’t be surprising. Whatever the case may be, the direction Peacemaker Season 2 is taking is certainly hinting towards a breathtaking finale with the way things are shaping out ot be. So, let’s wait and see what happens as the next episode comes out.
