About
His other attack is Phoenix Illusion Demon Fist (鳳凰幻魔拳, Hōō Genmaken), is infamous for destroying the minds of its victims—the technique is dealt from either a single fist or a finger. Concentrating his Cosmo into his fist to literally destroy his opponent's mind. Once used, it sends various nightmare illusions directly created by the opponent's brain; he or she is trapped within an illusion that is almost indistinguishable from reality. It also considerably weakens control of the Cosmo and depth of perception of reality. Ikki's Phoenix Illusion Demon Fist usually spells doom for the one in the receiving end—unless he has an unusually powerful mind.

In addition to weakening and trapping an enemy in a powerful illusion (followed by instant death) this attack also serves to delve deep into an enemy's mind - as was the case when this attack was used on Gemini Kanon during his reign in the Poseidon story arc and many other characters in the anime-only Asgard chapter.

In some battles, Ikki first uses the Phoenix Illusion Demon Fist to paralyze his rival, and then deals the Phoenix's Wings Rise to finish him off.
