The gods are not that powerful, they are just immortal and have extreme strength, Ken needed Aurora to be able to kill Hope, and she only lost in the first fight because she didn't know how to channel him, and yes witches can beat the gods if you didn't realize all those monsters were witches that Ken had to curse because they were reaching the power level of the gods and average witches can die if they use too much magic the only ones who died were Bonnie and Kai said Josie could die if she wasn't strong enough l to withstand all the black magic he received. Ken also said that there are gods who are born with few powers, which was the case with Jen, that's why he rejected her and the gods' powers are not many, they are just innate abilities that they can use such as making rain, casting curses, or breaking curses (the Ken's power was only two, casting and breaking curses, controlling the weather... flying, extreme strength, and regeneration, reading thoughts and manipulating memories just that, he didn't even have superhuman speed, were common abilities of the other gods, or could resurrect the dead, another impressive detail that explains why they couldn't bring Ken's mate from the dead. how were they invincible if nature gave them limits? you slipped into another detail, they didn't even create the dimension they lived a witch demonstrated the ability to create afterlife worlds, the Ancestors too, and Arcadius, and the gods couldn't, they weren't invincible if the witches could channel and absorb the their magic, the weapon to kill them was their own magic, surprised? ) Many have tried to argue that he has various powers but he hasn't shown anything beyond that, he couldn't resurrect the dead, couldn't go back in time those were apparently powers specific to the other gods, besides you despised Lynn's speech Ken's sister said there were limits to them since they left their world the Valhala or peace the home of the gods , and as I have repeated and will repeat again the gods are not that powerful they just have extreme physical senses as Jen has shown to be much stronger physically than an original, plus the fact that Ken doesn't could kill Hope without the red oak, he even tried but said numerous times in the episode that it was difficult to kill her and that she "refused to die", in addition to the fact that soon after Lizzie managed to channel Ken, and Cleo her. spear in order to kill him, and even that witches could not do because he prevented them from absorbing their god magic.
