In the image, there's the more important things as to how to draw Khress properly.
Might change something in the future if there's any data i think doesn't fit...
Down here we'll go with some abilities for another kind of written reference;
*Elementality; Khress can bend any element as is an extension of himself, Earth arise to the heavens just like a tail wag, oceans become raging if he's angry and calm down along with him, winds slice through mountains ravaging them as he sneezes, his cold stare literary freezes everything solid in absolute zero, lightning crash down when he's indignant, even light becomes solid if he wishes so. Elements; Light/Holy, Water/Ice, Lightning, Earth, Wind and Fire.
*Spiritus Factu: He's a spirit, and a major spirit at that, for all effect he has no body, he's just a solid spirit that can intereact with the material world, he can phase through anything as if they weren't there if he wishes so, and many other spirit related stuff.
Time&Space bending; kinda related to elementality, he can bend aven space and time themselves. Long distances can be traveled in a single step, Time may stop for all exceot him, making things/others younger/older is also easy. The time bending has a 'disguise effect; anyone/anything will perceive possible events as they witness the time shifting without even realizing time is shifting, i.e. If time stops and he moves place as time resumes, they will have the impression they saw him moving instead of a magical 'blinking'
Space bending cauzes reality shift, a solid wall can melt like butter if so he wishes, these effects are temporary though, needs concentration.
This also includes Gravity manipulation/bending with extreme maestry enough to create even black holes or dispell them.
*General Cheap Stuff Immunity: Untouchable Mind; Psychic powers and manipulative magic and anything of the sort just won't work on him, he can't be violated at all. Untouchable Spirit; Being a solid spirit makes he look like he has a body; he bleeds and is felt to the touch, but he CAN'T be; severed(slash attacks will get stuck/destroy blade after sinking barely half centimeter although pierce attacks will behave normaly), transformed against his will, possessed, has no one-hit-kill spots(although he has a seemingly pumping heart, it holds no significant importance to his survival, his eyes are actually the MOST resistent part of his 'body'). Untouchable Body; Having no living body brings many advantages; anything that affects the body of the living doesn't affect him; sicknesses, parasites, potions...for more effects imagine how bosses are always immune to any status change/overpowered skills in any game...he's almost like that...
Secular Magic; Ability to use arcane abilities of divine origin, basicly, a multi function magic range, using mystical artifacts and understanding them, to full on dispelling any encantations or curses.
Heal; Basic power of angels, the ability to restore life force and their vessels. This healing can actually reconstruct inanimate objects as well as plants, this power can't be used on self, it's only for others.
Celerety; Mixing natural overwhelming agility with natural ability to shift time flows, any speed/dexterity can be achieved.
Refragatus(Fightning Style); Sometimes gracious as Wu Chu, sometimes wild as a savage beast, this fightning style is a divine version of Tai Chi based on the phylosophy of using one's powers against themselves, but mixing in energy rediriction and brutal counters against brutal attacks, basicly any kind of infliction can be retalliated no matter how 'godly' in therms of level it might be, he specializes in counter measuring. Usually embelished with acrobatic moves, emphasis on kicks and flexibility.

Guess that's it for abilities ^^ Might add/change something if need be...

Weapon of choice; Bow, Katar, Chain and Magic Books. *Weapons usually conjured with space bending or made with elements*

Yup...powerful...VERY Powerful >:D
