Charmed which is the most powerfullest demon all time?

Answer 1

The most powerful demon on the show "Charmed" was Cole Turner, especially in season 5 when he was INVINCIBLE, because he could not be vanquished by any power, he had strong powers from the Demonic Wasteland, and he was the smartest demon the Universe had ever seen, or heard of. Second was Zankou because the Source feared him and needed to lock him away in a magical prison because he could not be vanquished by any force, the Charmed Ones needed to vanquish the Nexus while he had it so they could kill him, and his powers were unbeatable by anyone. Third was the Tall Man because the Source had to lock him away in a magical cage, made by the Seer, because he feared him and there was no known way to vanquish him, he had unknown powers and abilities, and it took the Source's Heir to eventually kill him. Fourth was the Source because he practically ruled the Underworld with countless demons by his side to do his bidding against the Charmed Ones and other evils, he sent his personal assassin, Shax, to kill Prue and he succeeded, and the powers and force he had were astonishing. Fifth was the Seer because her plan to get the Source's Heir was astronomical, the way she used her powers and the choices she made against the Charmed Ones and the Source were unexpected and unstoppable, and she could only be vanquished by the uncontrollable powers of the Source's Heir in her womb, once and for all.
