Natureza is the true number 10 of Brazil Youth, and a highly-skilled player who is rumored to be the Soccer King. He is the rival of the series' main protagonist, Tsubasa Ozora, and always tries to play better than the latter. Natureza's appearance is foreshadowed in some occasions, before he actually appears for the first time in chapter 63 of the Battle of World Youth arc, which is during the last minutes of the match between Brazil and Japan.
