The ending leaves El Cuco's fate deliberately ambiguous. While Ralph appears to kill it by crushing its head with a rock, the creature has already survived multiple injuries including gunshot wounds. The series suggests El Cuco might be a spectral force rather than a purely physical monster, raising the possibility it could return.

Foreshadowing: Earlier scenes show El Cuco surviving gunshot wounds and appearing to die only to revive.

In the final scene, Holly sees Jack Hoskins reflected in a mirror, despite him not being physically present. This suggests El Cuco has the ability to possess or take on human forms, meaning the creature's influence may persist even after Ralph kills its physical manifestation in the caves.

Holly's final line about outsiders underscores the series' central theme. El Cuco exists on the fringes of normal society, just as Holly does as someone who has experienced loss and trauma. The quote suggests understanding between those who exist outside conventional boundaries, whether supernatural or human.

El Cuco is presented as a malignant supernatural entity capable of surviving physical attacks. Evidence suggests it may be a spectral force rather than a physical monster, it survives multiple injuries, can appear without clear physical form, and visit people at night. Whether it can truly be killed remains uncertain.

Ralph, Holly, and Claude confront El Cuco in unstable caves. When Ralph prepares to shoot the creature, El Cuco warns him the shot could trigger a cave-in. Claude shoots anyway, and rocks fall, but all three survive. Ralph finds El Cuco playing dead after being shot, then returns to kill it with a rock.

Yes, the ending strongly implies El Cuco can possess or take on human forms. This is evidenced by Jack Hoskins being controlled by El Cuco throughout the series, and the final mirror scene where Holly sees Hoskins' reflection despite him not being there, suggesting the creature can manifest through human hosts.

Foreshadowing: Jack Hoskins was shown being controlled by El Cuco earlier in the series.

The ambiguous ending serves the series' themes of confronting the unexplainable and grief. By leaving whether El Cuco is truly eradicated open, the story suggests that darkness and trauma may persist beyond immediate resolution. This reflects how people cope with things that cannot be fully understood or controlled.
