God Channelers are a celestial humanoid species. After the events of Holy War took place in Generation 2, Carolina was created as the sole member of her species. When Generation 3's flipside rebooted into the Generation 4 universe, York was created alongside it, as the second God Channeler.
God Channelers meet somewhat halfway between mortal and god, being biologically immortal; where their life can only end in the event of significant sustained damage. Damage is the only way to kill a God Channeler, as they are immune to things like disease/illness.
Biology
God Channelers have the appearance of a human, though with some differences. For example, Channelers are typically much taller than the average human. For example, Carolina is 6'2" (188cm), while York is a whopping 7'0" (213cm).
As mentioned previously, the only way a God Channeler could be theoretically 'killed' is with enough sustained damage. This is to help prevent the possibility of a God Channeler going rogue. These celestial beings possess the ability to become invisible or intangible (though not both simultaneously). Despite both current God Channelers appearing relatively slim, they are made to sustain damage. In the near-impossible event a God Channeler is killed, they will release a burst of energy in the form of an explosion, about the size of the solar system's sun.
Whereas humans are largely comprised of carbon, God Channelers share a similar makeup, with dark matter in place of carbon. Other differences include hair that, naturally, is much more detailed than regular human hair. Channelers also have what can be described as "void eyes," where an eye shine nor pupil are present (and this isn't due to malice). The final thing of note is their swirly eyebrows. The only non-God Channeler character to exhibit this trait is Aerosmith from Strings of Fate, though it should be noted he modified the look of his eyebrows himself to better fit his air/wind theming.
When a God Channeler is created alongside the universe, they will first not be a humanoid; instead taking on the form of an orb (more on that later). After 100 years, the Channeler will retreat from their orb, with the physical maturity of a human that is in their prime (~25 years old). In most cases, God Channelers are cold and mostly insusceptible to emotion, though this phenomenon can vary based on their gift.
God Channelers boast a wide set of abilities. There are three kinds of abilities a God Channeler can use; biological, gifted, and generational.

Biological abilities are abilities that come with being a member of the God Channeler species, such as, but not limited to:
Invisibility
Intangibility (can't be used with invisibility)
Minor shapeshifting
(can change size, grow extra body parts, stretch/scale existing body parts, etc.)
Teleportation
Flight
Gifted abilities are abilities that come with the Channeler's title. Each God Channeler, upon creation, is dubbed "The Channeler of _____." For example, in Carolina's case, where she's The Channeler of Life, she can:
Recover faster than the normal speed of a Channeler
Revive the dead (she chooses to never do this, due to a fear of universal imbalance; plus it uses lots of stamina)
Heal anything
Carolina can create new life, so long as it's not a humanoid species (i.e. other channelers, elems), or a species with a dynamic soul (i.e. humans, almans).
Finally, generational abilities mean that a God Channeler has access to every single ability introduced in their respective generation (not counting remakes of stories from previous generations). This means that Carolina has access to:
All eight base types of magic (Strings of Fate)
Typeless magic (Strings of Fate)
Dark magic (Equinox and Second Chance)
Malice, despite being pure of heart (Second Chance)
Cora, mente, and elemena (Soul Strike)
The only exceptions to this is familiars (Equinox) and alma (Soul Strike), since a familiar is a magical/otherworldly being, which Carolina is already considered. Meaning, in a sense, she is her own familiar. And in alma's case, her gifted abilities already cover that base.
A God Channeler's abilities may come with drawbacks, like in York's case, who can suffer from migraine-like pains from overexertion.
Death/Dormant Form
If a God Channeler dies due to damage, their body will glow white, transform into a pure white ball of energy, and explode. This explosion can, and most likely will wipe out anything that's caught in it.
If a God Channeler wishes to, they can retreat to their dormant/orb form. This orb still has some level of consciousness, however; and if a God Channeler wishes to come back, they may (with some exceptions). The orb doesn't have enough consciousness for things like dreams or memories to exist, meaning that the orb won't remember why it turned into one, but just whether or not it would like to remain as one (for example, if a God Channeler grows tired of existing; which shouldn't happen, but the option is there).
A God Channeler can retreat into their orb form as a means of saving their own life in battle.
It's in a God Channeler's nature to not prefer to 'orb,' as entering the form means the user can't return to normal for 100 years.

Weaknesses
Currently, only a very small list of things would pose a threat to a God Channeler.
Another God Channeler
The only being that, by default, should be able to take on a God Channeler, is another God Channeler.

Gaboza, when wearing the Creation Crown, has full control of everything he's ever made. This gives him the ability to delete God Channelers at will, should one of them cause too much trouble.
