At the end of the battle, Menthuthuyoupi had matured to the point where he reached his "Rage Incarnate" form and was even "thankful" to the Hunters in helping him achieve this form.
With a double strike to the ground, he created a crater and caused the whole tower to collapse.
According to him, none of the members of the Extermination Team he encountered had so much as a tenth of his raw power.
