The main antagonist in the Alien franchise that Ripley confronts may seem like the Xenomorph threat, but it is, in fact, the morally bankrupt Weyland-Yutani. The inclusion of this mega-corporation allows this series of films to address prevalent themes of labor exploitation and corporate greed. These themes collectively contribute to the dark and dystopian atmosphere of the Alien universe, offering a critique of unchecked corporate power and the consequences of prioritizing profit over human well-being.
