Alien Conquest LEGO sets

10 official sets in the Alien Conquest theme.

The Alien Conquest theme includes 10 official LEGO sets in our catalog. Each listing links to a full parts inventory, minifigure breakdown when available, and official build manuals you can read in your browser.

Alien Conquest sits under the broader Space theme on LEGO's product line. Collectors often browse both levels — parent themes for overview, subthemes for specific eras or licenses.

Use the grid below to explore by release year, then open any set to verify loose parts against the inventory or check market estimates before buying or selling.

Collector tips

→ Sort bulk lots by checking printed tiles and minifig torsos first — they often carry more value than common plates.
→ Compare color variants on part pages before listing; the same mold in different colors can have very different market prices.
→ Open build manuals on set pages to confirm bag contents when rebuilding incomplete copies.
