| Film | Number of Fingers | Description |
|---|---|---|
| Alien (1979) | Six | The original Xenomorph has webbed, six-fingered hands. The fingers are often held together, giving a fused appearance, but are distinct digits. |
| Aliens (1986) | Three | The design was simplified to three fingers: two paired digits and one opposable thumb. They appear longer and more skeletal. |
| Alien³ (1992) | Four | The "dog" or "runner" Xenomorph has four digits on each hand, continuing a more animalistic, quadrupedal design. |
| Alien: Resurrection (1997) | Four | Features four digits: two long middle fingers and a pair of opposable thumbs. The hands are bulkier and more fleshy. |
| Alien vs. Predator (2004) | Four | Retains the four-digit design from Resurrection, though hands are made bulkier for combat with Predators. |
| Aliens vs. Predator: Requiem (2007) | Four | Continues the four-digit structure, consistent with the previous AVP film. |
| Prometheus (2012) | N/A (Not a true Xenomorph) | Features the "Deacon," a different xenomorphic creature with distinct, non-canonical limb structure. |
| Alien: Covenant (2017) | Five | The "Neomorph" and "Protomorph" (or "Chestburster") display five-digit hands, marking a return to a more humanoid structure. |
| Alien: Romulus (2024) | Six | Returns to a six-fingered design, with two opposing thumbs and four digits, reminiscent of the original but with modern articulation. |
