Stikua should take D's spot in High 6-B, he does not resist Power Absorption, Corrosion Inducement (Passive), Immortality Negation, or Information Manipulation.
Secondly, he should take Oryx's spot in 2-B. He does not resist Death Manipulation, Fear Manipulation (Passive), Soul Manipulation (Passive), Absorption, or Sleep Manipulation. (All work on Abstract, Non-Living, Etc beings.)
His sheer Immortality is so potent he can simply survive without his Mind, Body, Soul, Concept, Information, or Story. Of course, he could regenerate all of that if he wants, but even if you do somehow kill him he has Immortality Type 4 & 8 based on something entirely separate from the things mentioned above.
And lastly, he would need to touch Stikua, who is a literal story that is neither real, nor unreal, virtual nor material, and beyond all of that is abstract beyond abstract concepts, laws, plots, etc. (Oh and his powers are as abstract as he is.)
So... Ya...
