RAD-UM (Undead Mutants)

RAD-UM, or simply just Undead Mutants are a sub-genre of the Mutants (RAD Creatures) in the After the Flash series. This class of mutants was created by BoaDaSnakeMan and is not canon to the main timeline or official lore by ChadTheCreator. They are featured in the story "After The Flash: Wrong Turn" with Nick Schlect and Valentina Isla Josephine as the main protagonists.

This type of RAD is commonly found north of the United States and continues further into Canada. They were unintentionally created this way due to the vaccine not being fully completed because of an unfortunate unidentified military presence raided the facility. The disease can still kill of RAD or convert it to RAD-UM. This disease also has a unique traits to be able to infect humans with weak immune systems or if they are deceased, bringing them back lifeless.

The most common type of RAD-UM subjects are mutants, this may imply that the disease is working at a certain state but still converts the mutants to a zombified state. The disease cannot be carried over to humans via scratch mark or bites. Animals are also carriers of the disease which makes it more dangerous for humans and mutants alike.

Anything above RAD-6 will not live to become RAD-UM or any form, by this point the RAD-UM will fully kill off RAD-6 or higher due to the high existence of RAD. It is unknown why the disease does this and scientists say that its due to the high nature of RAD living in their blood.

No Undead Mutant have no authority over the other and do no share a mind. They scatter across the northern region of the United States and Canada with no certain base or nest of operations. They lack intelligence and will attack at will even if someone possesses a firearm. They also seem to not care for gunshots at any means. They have increased hearing and sense of smell and will let out a screech if they see any humans or mutants, this will alert other RAD-UM to their prey.
