8] The Feline Bureau of Investigation
9] K-On!
10] The Angelechy archetype
11] Cicada killer wasps
12] The confirmed Abilities for the Z-A and Mega Dimension Mega Evolutions, as posted here and here
13] A combination of all of the above? 
I'm guessing this has to do with XOver somehow? I asked a similar question (top 3 for most/least favourite design from each Generation) though King's only answered for Generations I to VI:
7) Castle Oblivion being a post-game area for rematching bosses from other Kingdom Hearts games sounds interesting.
8] Better than the actual FBI.
9) An anime that I've never watched.
10) So it appears to be a Chess themed archetype. OK. I wonder if it has a black counterpart considering that the Angelechy monsters are all white.
11) They're bigger than regular Yellowjacket wasps, similar to hornets.
12) Multiscale and Eelevitate sound interesting.
13) Very chaotic.
