Ghost Ash is NOT some kind of evil, cute softie that just likes absorbing souls and torturing beings for no reason. You can NOT defeat him with only some stupid UV light. He is NOT powerless, and he speaks in RED. (Gaster referen-)
Ghost Ash is a floating sharp-edged black cube from the shapes universe. His paws and tie arent attached to his body, and his hat cant be removed due to corruption
Hes possessed by Mega Octagon, and has TWO souls inside him; Ash Foster's and Mega's. The corrupted one is stronger, which is why hes always like Mega.
For powers, he can manipulate (move and reshape from afar) gravity, energy (light, sound, etc.) and objects. He can create portals through dimensions or in the same dimension.
He is physically INDESTRUCTIBLE, meaning you cant just rip his soul out or stab him or whatever. The only thing that PHYSICALLY damages him is pure shortwave UV energy, which he can DODGE and REDIRECT
For personality, he is literally insane. Hes always so calm, sweet and flirty. He ALWAYS smiles, even if hes in f**king agony. He never gets shocked, only surprised, in disbelief or a little speechless. Hes a little sarcastic and mocking with powerful beings, depending on how dangerous that being can be. Hes nonchalant and casual about EVERYTHING. Hes a master manipulator and a master mind. He only gets a litte grumpy and annoyed with idiots
He does NOT attack unless he has to physically defend himself. His style is always manipulation dipped in honey, which is lying to get what he wants through his sweet voice. He doesnt enjoy killing, he enjoys torture, but he only uses that when he has no other choice
He may be physically overpowered, but no, he has a massive mental weakness, which is how unstable his souls are and how insane it makes him. A single word or sentence, for example "Violet is your sister, Ash Foster," wouldnt trigger his uncorrupted soul. The only things that trigger it is intense emotion like grief, sorrow, guilt or being reminded of Ash Foster's memories with details. His corrupted and uncorrupted souls will be fighting for control, meaning on the outside he'd go even more insane and unstable, which is his weakest state
I hope Ash never gets misused now
