Ninjago · Series · Scythe Master, Ghost General, Cursed Ghost
Like any other ghost, his primary weakness is water, which is able to harm him regardless of his durability, and decent amounts of it (like a bucket of water, or even a teapot) are enough to one-shot him, though this weakness becomes irrelevant when possessing someone or something, and even if destroyed, he can regenerate immediately in the Cursed Realm. If he possesses a person, the host may try to fight him back, weakening him in the process. Deepstone armors make the user immune to the ghosts' powers, and much like water Deepstone weapons can one-shot any ghost regardless of their strength (unless, of course, the ghost is possessing someone/something). Ghoultar himself isn't very smart, so he can be tricked without much difficulty.
Ranked tied for #17 of 70 in Ninjago by strength.
