Experiment 7526 was an unsuccessful attempt at converting a Space Pirate into an Elite Pirate. Its remains can be seen inside a tall, indestructible Xenome Containment Unit in the Research Lab Aether room of the Phendrana Drifts, in Metroid Prime.
Interestingly, it resembles a Zebesian moreso than any other Pirate on Tallon IV.
"This tank holds the remains of experiment 7526. Conversion of Elite Pirate unsuccessful."
E3 2001 concept art of Prime depicted a creature that shared superficial similarities with several other creatures, such as the coloration and head of the Parasite Queen, tentacles of the Metroid Prime, a claw like that of a Zebesian and a translucent membrane with an inner nucleus reminiscent of most standard Metroid types. This creature highly resembles experiment 7526. An anonymous developer from Retro Studios later revealed that this creature was a scrapped enemy, a mutated Space Pirate that was a failure in the Pirate Phazon experiments. It was then repurposed as background fodder.
