Fun fact: They are actually very slightly different. Dawn and Lucas have more of a blue-ish black hair. While the legends protags hair is just straight up black black. No blue.
Pokemon Z confirmedThe protagonist not even being from Sinnoh/Hisui aside, the fact that it's seemingly modern-day Kalos of all places is definitely interesting. Given their resemblance to Lucas/Dawn, well they won't be returning home lol
