With regards to Hyperion, would just like to point out that as an untrained, virtually comatose teenager, his psychic power was enough to burn out a blank's null aura, effectively turning them into a normal human. The only other thing to achieve something similar, from what I can recall right now, was a demonically possessed titan (beings like Malcador, Magnus and the Emperor have shown themselves to be unaffected by blanks, but not to actually burn them out, though the Emperor could in all likelihood do it, if he were so inclined). So, in terms of raw power, Hyperion is definitely amongst the most powerful psykers to appear in the fluff.
The human appendix. Proof of a higher power. A divine kill switch so to speak.
No one really likes a smartass, but people tend to like a dumbass even less.
