I'm feeling evil and-- well, you can answer these when the Scarlet/Violet games release in a few weeks, if you want. (Or just edit your reply. Or shove me off a cliff into
a Bloom Beast's nest. Or something. :p )

These are all "top 3" by the way.
These can be design-wise, or because of fond memories of using said Pokémon to curb-stomp that annoying laughing old timer Gym Leader Wattson one opponent, or favourite cry, even. :p

Out of the standard Grass/Fire/Water Starter trios…
1. Favourite first-stage Starter Pokémon?
2. Favourite second-stage Starter Pokémon?
3. Favourite third-stage Starter Pokémon?

Out of the non-Starters:
4. Favourite first-stage Pokémon?
5. Favourite second-stage Pokémon?
6. Favourite third-stage Pokémon?

And now some entirely random Pokémon questions just for the heck of it. :p
7. Which Ultra Beast would you associate with me? :3
8. Most memorable Pokémon cry, to you?
9. Favourite rival and villainous organization?
10. If you were a Warlord (like those in the Ransei region), which Pokémon would your perfect link be with? (Doesn't have to be restricted to those found in Ransei, but it does affect your Warlord transformations, I guess?)

11. You look out your window to see a Gigantamax Pikachu looking at you. What do you do?

12. You open the door to find a Mega Evolved Pokémon holding a Poké Ball. What Pokémon is it?

13. You receive an envelope from a secret admirer. Inside it, is a Z-Crystal. What Z-Crystal is it?

14. You run into a group of evil people who seal people's souls into cards. Do you challenge them and give it your all to defeat them, or do you run for the hills and hope they don't give chase?

15. A beautiful blonde princess with green eyes invites you for a dinner, at any (real) location of your choice.

16. Which Nature would best describe: (a) you, (b) a loved one, and (c) your ideal love?
17. Out of all the cross-generational evolutions introduced in Generation VIII (including those of the regional variants), which has your favourite colour?
18. Best battle theme from every Pokémon game that you've played? (Or at least, those that are memorable.)
19. Pokémon Contests, Pokémon Musicals, or Pokéstar Studio?
20. You wake up in the Pokémon world as a 10-year old Trainer about to start a first journey. Which region are you in, and what Starter do you pick?

And now, freedom from Pokémon questions, haha. >:3

21. Are you pleased with all these questions?
22. Favourite mythological deities? (Minimum: 3.)
23. Ness has granted you one special power, but at a cost. What power is this, and at what cost?

24. What is the velocity of an unladen swallow?


And for the final touch…
25. On a scale of 1 to 100, how Flower Dragon is this post? :3
