Hi, welcome to Fairy Tail Wiki! Thanks for your edit to the a good burger page.
Re: Romeo Edit
The manga didn't make a mistake, the translators of the manga, Mangastream/Mangareader/Mangaheader etc., made a mistake. The names we have for the characters are directly from Mashima. Romeo's name is Romeo Conbolt, but many sites mistranslated it as Romeo Combolt. Hope this helps.
