Zombie researchers are people found in the GBA video game Metroid Fusion. This is a Job class that the characters in the game have in addition to other class types such as Space Pirate ect ,ect. The Zombie researchers are people in the game that have been infected by the X-Parasite. Once a zombie researcher dies, the X-Parasite that infected its body will emerge, allowing Samus Aran to take it in for health or ammo. However, if she doesn't manage to get ahold of the X-Parasite, then it will re-enter the dead zombie, thus reviving it.
Still, they're not very bothersome, seeing that only one shot will take it down.
All zombie researchers are purple and have orange colored clothing.
