Fright Height has the appearance of a goblin. His body is a mix of orange and black; the majority of his skin is orange, save for two bands around his wrists, a stripe going down the middle of his face and chest, torn shorts going to his knees, and bands around his ankles being black. He has a set of withered wings connecting to his arms and his back, which are also orange. He has pointed ears and five clawed fingers; he also has two clawed toes.
Primarily from his mouth, the acid is built up inside of him. He has an extra organ that creates the acid and it doesn't interfere with his bodily functions.
Nightmare Imprisonment
Due to the nature of him being that of a goblin, Fright Height can trap his foes in realistic nightmares with his gaze.
Invisibility
Fright Height can use his wings as a means to activate a special feature in his skin that turns him invisible.
Due to The Gamma Awakening being canned prior to release, Fright Height's scrapped abilities, nightmare inducement and invisibility, were never showcased.
Thank GOD for CaT, these abilities are utilized in the Project Deca episode What CaT Dragged In.
