THE IMPROVEMENT IS REAL HOLY CRAP I JUST REALIZED
Anyway.. have you wanted to make a hybrid? Make an infected version of your OC? Well now you can!
You're probably wondering, Really? What do I do? What are the requirements?
-Well, First it just has to be a creature of literally any kind. It just has to be a combination of two.
-You can make up your own species as well! Ex: Demon-Hanger, Sea-Illuminator, Dhampir-Taker
(I've been going with the trend: Species and a physical/emotional trait or something they specialize in)
-Be Creative with names! Some Name ideas (that are taken) are Blaze Angler Everlone, Cozmo Aquorvarce Ingloude, Kiwi, Lewis, Mango, Victoria, Boroan, etc. (I REPEAT YOU CAN'T USE THESE. THEY ARE TAKEN)
-They need to be appropriate for the time (basically, they have to be in the 1200's)
-They have to have a way that they died (By Humans Preferably) Ex: Torture, Murder, Starvation, Poisoned, Frozen to death, etc.
-Here are examples of Hybrids (some aren't mine because they are made by someone else)

Her name is Kiwi, she is Dhampir-Taker (Belongs to DryFox)

His name is Louis (Belongs to Drastic Dragapult)

Her name Mango (Belongs to Doomfox)

Yes Neph is a hybrid. She is a Demon-Angel.

Blaze is a Demon-Hanger. His father was a Hanger, his mother was a Demon.

Yes Victoria and Boroan are Blaze's Parents so there you go.
If you want an infected Oc there a couple things to know about that too
-An option is having an infected side of your OC with your hybrid. (Having the spirit of the hybrid possess the OC)
-The hybrid has to have some kind of family, friend, or foe (etc.) relationship with your OC
-Tentacles, Black Eyes with red pupils, Chest Mouth, Sharp Teeth, and Black coming through the eyes, arms, mouth, and tentacles are all needed.
-You can make your own tentacle design!
-once again, be creative with names! Ex: Salync, Kakori, Gulvic Strangler Severtone, Ryzo Bloorwarce Fingzroud.
(You can do what I did and choose words that describe your infected. Ex: Gulvic- Strangle, Sever Tone
Ryzo- Blood War, Fang Loud     Cozmo- Aquatic Universe, Single Proud Blaze- Angle, Forever Alone

But yea have fun with this! If you have any questions just ask! :3
