Yu☆Gi☆Oh! Duel Monsters, Dr. Stone Recommendations
Both series feature savant's and genius/prodigy main characters with great & unique hair. Both are based off popular shonen JUMP manga. Main cast of characters are of similar ages (high school ish) and also had almost ordinary school lives where they made some of the friendships they maintain on these extraordinary adventures. Both series also have amazing art styles, character designs and OST's.
