What if hisoka had His Top 20 Anime characters from Across all the animes?... Well I will make a list in his Place cuz I don't think We will get to hear his opinions on this even in a century or so cuz Of the Hiatus but sure.
Anime name is Hunter x Hunter btw. (idk how could anyone Not know Who hisoka is but yeah)

20. Dio From JJBA (similar Minds Attaract each other. They Would probably Join each other to Go After JoJos For generations..)

19. Mob (well, Hisoka is good at "Sensing stuff" i guess.. he Would Sense his Potential of being at 100% and would go after him?)

18. Nobita (...)

17. Shinchan (He has immense potential You know? He just.. need time to ripe .. -words of Hisoka)

16. Chopper ( i dont know how to explain this one but i geniunly feel like he will Like him In a good way for some reason)

15. Ash ketchup (yeah they will do a pokemon battle. Thats for sure. i wonder what tactics Hisoka Would use to win against A 10 year old? He will still wait for him to get stronger i guess?)

14. Damian DESMOND (the rich kid from spy x fam. He has Way too much "potential")

13. Emma (from the promised neverland.. he has way too much potential I just can't leave him out of the list)

12. Madara (y'know He kinda like chrollo tbh, Shady guy who is too strong. He Lowky will beg to fight em)

11. Nel tu. (Yes The one from bleach. He would totally sense Her potential... Why am i using the word potential so much.)

10. Kimblee (From FMAB. They really similar tbh. I would love to see them meet)

9. Made in abyss kids (Yeah yeah yeah, Tragic Lives .. Immense potential, great work for kids, Adventure In fantasy theme... Seems similar to some Kids in Hunter x hunter right?)

8. Anya (................ Immense potential... Yeah she has, She is a supernatural kid.)

7. Tatsumaki (Gon's momma. Atleast that's what hisoka Would think. And she is really strong as Well)

6. Gohan. (no seriously tho. He is perfect. Hisoka would be Obsessed considering how much of criterias he fit)

5. Deku (Brotha of Gon. )

4. Saitama. (Need explanation? I guess not)

3. Gojo (big version of killuaa (killua is kinda His papa considering Time gap on when Series came). He is also really strong to attract Hisoka)

2. Zoro ( big version of gon. Would def Attract hisoka. Hisoka would Fill out of Joy seeing, Gon's potential there. He would think Gon Got magically grown up. I can see Hisoka Chasing him after Zoro Came to HxH verse while he was in a walk)

1. Gon, killua, Chrollo. (Any Questions? I kinda included them at 1, cuz everyone already knows they are thier fav)

0. Me (Im Hisoka's biggest fan so ofc He will Like me)

Well... Uh. Guess Im missing someone really iconic to be Hisoka's Fav. Idk man but i get the feel of that. But sure. Today this wasnt published by the larping federations its source was...
