Void Gaster is a being shrouded in mystery, making it hard to understand his true nature. He exudes a cold and calculating aura, and his presence commands respect and fear. He is fiercely intelligent and analytical, with a deep understanding of the workings of the multiverse. He values power above all else and believes that the strong should rule over the weak. He rarely speaks, but when he does, his words are precise and calculated. He has little feelings others only caring if it benefits him.
