Gomaruh

"You should be honored. No mortal has ever made me use this form. Now I'll finish this for once and for all. I'll cause you so much pain you'll beg me to erase your existence. Come on then, Cry! Cry that there is no meaning to your pointless lives. Cry that there is no justice in your world. Cry that there is no salvation. There is no hope. There is no end to your suffering. There is only me. I am all of you mortals."~Gomaruh when assuming their true form while fighting matt and his allies

Appearance
Ruh has changed their appearance many times, when they are outside of a host they appear as an insect like creature with black smoke and green lines, this color scheme of black and green remains consistent in all its forms, in matt' s era they first assume the forms of a fake little sister and fake father for matt, they later look like a humanoid creature with a muscular torso, insect like head, big claws, bone wings and tentacles with white screaming faces all across their body, they later assume a shape similar to the upper half of a human partially in the ground, their arms are in the ground, they lack any facial features aside from the screaming faces covering the face area, they have several tentacles coming out of the ground with more screaming faces on them, in jordybot's era they first appear as a large mass of circular shapes with tentacles, eyes and mouths coming out of it, they later appear as a gigant dragon with large wing, six legs, large teeth and green eyes, in lea's era they appear as a large face

Personality
Ruh is the manifestation of all evil, they lack any empathy or morals and actively seek joy in making others miserable, they enjoy seeing people be in both physical and emotional pain, though ruh does understand things such as love they only use this knowledge to manipulate people or cause them even more suffering, they are very intelligent and good with words being able to easily convince people like eric and erin to join them however they only see their servants as pawns and they don't care about them other than as a tool for their plan, according to ruh themselves they want to cause maximum suffering to all life and once all life in the multiverse has succumbed to despair they will destroy all life and then themselves as they would've fulfilled their purpose
