Truth Idea has already been explained.

"Truth Idea's effects depend on God's will in the Holy Spear and absorbs the wielder's ambition of this spear, and by responding to how strong the opponent is, it will create many effects and miracles which will be different depending on what the will chooses such as granting an absolute power to destroy the opponent or a blessing to the opponent to capture their hearts."

Which i don't think will work in this case at all since i doubt the absolute power to destroy opponent can be something that is on par with Great Red/Ophis/666.
