Beast overlap

When the Beast DNA inside of people from the gov experiments tries to override the original human DNA and show outward physical characteristics of the Beast in the person

Nothing to really do with genetics, I guess its the Beast genetics and if they are in you or not

If you survived the injection

Un-transmittable

Depends on the type of Beast

Scorch Beasts will make the owner appear to be made of lava, or made of fire itself, almost like the sun.

Depth Beasts will make the owner become covered in barnacles and coral, with webbed hands and feet and gills.

Chasm Beasts will make the owner grow jagged or smooth rocks along their bodies, like their spines or wrists and ankles, and will have flowers and other flora grow on them.

Altitude Beasts will make the owner sprout wings of feathers or skin, talons like knives on their hands and feet.

Lots of body trauma with undergoing Beast Overlap, especially if unexpected.
Can feel like fighting against yourself, like you have a raging beast inside you that just wants to destroy and hunt.

Feeling extremely hot or cold for Scorch and Depth beasts,
Having pain in your back or where the rocks are forming for Chasm and Altitude Beasts.

Until you take the suppression meds or wait until it's done and you are able to switch between forms, this process could take anywhere from weeks to years

Everyone with this condition is given pills they must take on a daily basis to keep it at bay.
