So... When the Umbrellaverse deities are needed to fight, they aren't physically transported anywhere. Instead, when the need arises, each deity will immediately go into a comatose state, all at the same time. They then appear on a different plane of reality, although their physical bodies remain where they were. (kinda like an out of body experience.) When the deities engage in battle, they have bodies that are identical to their physical ones, called Plane Forms. When injured, a deity will have both their physical body and their plane form affected, and if they die in battle, they physically die.
A little scenario to help explain...
Say Kora, Elijah, Zacharie, Sombra, Jojo, and Jamal were hanging out together and the deities got called to battle. No matter what they were doing, Kora, Zacharie, and Elijah would immediately collapse at the same exact time, and they wouldn't wake up until the battle was over. If one of them was hurt, their injury would appear on their physical body, however if their physical body gets hurt, their plane form isn't affected at all.
.
Okay, that's it for now. Next up, I'm gonna be explaining the appearances of the Great Yeeter and the Great Yoinker, and each of the different forms they can take. I might start an rp later, if anyone is interested.
