Chara and Asriel can both destroy existence. Every timeline, each having their own universe, can be destroyed. The reason Chara in particular is so powerful is because they not only destroyed the  multiverse, but also brought it back with one soul. Asriel needed 6 human souls and every monster soul to do this. Also, Chara made a permanent change to all True Pacifist Timelines. Frisk may be an ordinary human, but they can fix any mistake they make, and with their determination telling them to not give up, they will most likely defeat any opponent without reality warping powers.
