Here's the votes so far, and I'm shocked.
Ash has 9 votes, meaning he's the 3rd most hated. Might be him being on the main cast for too long and his personality.
Brock hasn't received any votes! Looks like everyone likes him.
Cilan has 3 votes, making him tied with May for 6th least fave.
This is why I'm shocked, you guys voted Dawn as the most hated with a total of 20 votes! She's actually my fave character! I guess it's because of personality you gave her so many votes.
Iris has weird-looking hair, but you actually voted her as the 5th least fave with 4 votes.
Max is the little glasses kid from Hoenn. Tied with Pikachu for 4th least fave with a total of 5 votes.
May is tied with Cilan on 3 votes as the 6th least fave character.
Misty is currently tied with "other" for 2nd least fave with 10 votes. That's 8 less than Dawn! Maybe Misty's fear of Bug Pokemon could be the factor.
Tracey has 2 votes, making him the 7th least favourite. He has 2 more votes than Brock, who hasn't been voted at all!
Pikachu is the 4th most hated in this poll.
Other characters are tied with Misty for 2nd least fave with a 10 votes.
