Do you think Ritchie is a useless Side Character?

No, not at all. Richie is an interesting character that has the same dream as Ash :)

No. He was quite useful in the Butch & Cassidy and Lugia eps. But he could have better taste in names for Pokemon...

70% yes 30% No. He his helpful in someplace but other times he is not well needed. I agree with AKetchum he needs better taste in nicknames of pokemon

is he the one who has a pikachu named skarky???
