2- Well Satotz said that it was an ecosystem that survived on deceiving humans, and all of the creatures features were tailor made to trick humans who were running. So without humans there, their traits would just kind of fade out due to evolution.

3- Oh okay. Sorry for asking it again then. Also, now that I think about it, the full fight wasn't shown. So Togari could very well have used a Nen ability offscreen.

6- I can't say that I agree with you there. I don't think it matters if they know about Rock or not. If he uses Scissors right off the bat, it would be more useful than using Rock first. That way, if it hits, the enemy should be dead. If he uses Rock first, even if it hits, it might not do significant damage. If it misses, then Gon just wasted a ton of Nen, and gave the enemy a perfect opportunity to attack.
