Through the power of "Doppelgänger," Aiden replaced his appearance with that of the Revenge Goddess.
It was impossible to deceive the higher-order "Revenge" power's summoning of revenge using only the basic "Doppelgänger" ability.
However, according to the Revenge Goddess, this body now hosted two souls, which could create a certain degree of interference in the revenge summoning. On this basis, using the "Doppelgänger" ability could cause Mr. Red's revenge summoning to lose its accuracy over long distances.
Besides, the Revenge Goddess had mentioned that if she were given control over the body, "Aiden Galahad's" existence could be completely concealed, leaving only the appearance of the Revenge Goddess, Phoenix Lady, thereby completely deceiving Mr. Red's perception.
Naturally, Aiden could not agree to such a proposal.
