Necrons (Warhammer 40,000) Versus Samus Aran (Metroid Franchise)
With a fresh bounty list in her database, Samus is set to find her quarry when a sudden Warp Storm catches her off guard and transports her into the 41st millenium. She makes an emergency landing on the nearest planet to check of major damage to the ship before she starts exploring. Her initial scans bring up odd readings, and then things start getting crazy as the Tomb World she's landed on begins to awaken...
Samus is at full power for this adventure. We'll assume chronological, so Fusion-era, I suppose. This can be adjusted if need be.
Can she discover the secrets of this deadly planet and escape before she is destroyed? Can she find a way to remove the threat the planet presents to the galaxy?
Bonus Round: An (appropriately scaled) Astartes fleet is in range of the awakening Tomb World and deploys. What do they find on the surface? Do they come to Samus's aid, or target her along with the Necrons themselves?
Or do the ancient warriors conquer all?
