Graveyard planet

A "graveyard planet" appears in chapter 7 of Metroid EX.

Samus, Joey and Diesel come here in search of intelligence about the Greed Corps, but instead find a graveyard. They are even more shocked when they find the names of the Deadly Six Stars on the tombstones. Suddenly, the Stars emerge from their graves as zombies, and combine into one beast. Bishop and Knight, two of Greed's henchmen, appear. Bishop explains that the planet is filled with the spirits of villains Samus has defeated in battle, which now haunt the planet in search of vengeance. Knight destroys the monsters against the former's wishes, believing them to be inferior to Samus' combat prowess. The monsters are revealed to be robots despite what Bishop said. Knight proves himself a worthy challenger to Samus and urges her to continue fighting him.
