Why is Phoenix afraid of the crimson witch?

The red witch is stronger than Fung Wong-Nui. Fung Wong-Nui is afraid of scarlet witch, because scarlet witch can erase the traces of Fung Wong-Nui and easily wipe out all the mutants in the world.

In film and television dramas, the strength of the Crimson Witch and Fung Wong-Nui has been weakened to varying degrees. However, according to the original design of the cartoon, the power of the crimson witch has toppled several streets in Fung Wong-Nui. For example, Fung Wong-Nui at her peak can only change the reality of one-dimensional world, while the crimson witch can permanently modify several worlds at the same time.

The crimson witch uses chaotic magic, and the power of chaos is creation and annihilation. Comics set the explosive power of the crimson witch at its peak to obliterate the existence of mutants and even restart the omnipotent universe. Even the protoss can't stop the crimson witch.

Fung Wong-Nui is the only five-level mutant with Phoenix power, who can read minds and control or change the world through thoughts. But Fung Wong-Nui at her peak can only change one world, while the crimson witch at her peak can influence several worlds at the same time.
