Well, in Taringa (Spanish Speaking Community) there is a Cabronie known as “Pegasus BTX” who interviewed Isabel Martiñon, great Voice Actress who dubbed Naruto Uzumaki, Ben 10 , Otto Rocket, and now, Spike the Dragon , at Puerto Vallarta’s Comic Con.
She commented that the comments of the users influenciated the change of voices, Applejack as an example, who is now voiced by Claudia Motta.
She also said that she really liked her character:
“Spike is a really cute character. It’s the tipical kid who wants to act like a grown-up, but he’s still a little baby dragon. It’s really cute”
And for last, she said that she actually didn’t recieved complaints about her Voice Acting, instead she was elogiated for her awesome work.
