It's not Rival, it's Advanced Adventure.part of the lyrics in 'Rival' one of the Pokemon themes.
Ash got one as a WAAAAAAAAY begining of the works moment. Back when Nintendo of America was using the "Gotta Catch 'Em All" slogan. Ketchum was pretty much a pun off of that.Psydaquil said:If ash Got a last name, May should of too.
it's non-existant. Just like Brock's and Misty's last names.
Misty is the reverse. Never given a surname in her English dub, but apparently in the 3rd film reveals the Japanese surname "Yawa" or something.
