How old do you think each protagonist and rival/friend character are?

My personal headcanons for characters without a canon age are:

Ethan, Lyra, Kris, and Silver: 12-13 years old (based on their height and weight)

Dawn, Lucas, and Barry: 10-11 years old (based on their height and weight, Dawn and Lucas are so tiny)

Nate, Rosa, and Hugh: 14 years old (i know Hugh is said to be 12 in Adventures but I personally think theyd be young teens in-game).

Serena, Calem, Shauna, and Tierno: 16-17 years old (Serena and Calem were said to be older than Emma during XY but they're referred to as children by Lysandre. I believe Shauna and Tierno are around the same age as them).

Trevor: 15-16 years old (I think Trevor is a little bit younger than the rest of the gang in XY, maybe by a few months to a year).

Gladion: 13-14 years old (he's most likely at least a bit older than the others and most likely a teenager. His concept art also said he has "middle school arrogance.")

Chase, Elaine, and Trace: 11 years old (based on vibes)

Gloria, Victor, Hop, Marnie: 12 years old (also based off of vibes tbh)

Bede: 13 years old (I think he's a year older than the others).

Klara and Avery: 18-20 years old (theyre confirmed to be adults but I dont think they're far into adulthood).

Adaman and Irida: 18-23 years old (theyre older than the protagonist but still young. id say they're late teens to early 20s).

Florian, Juliana, Penny, and Kieran: 14 years old (Kieran is confirmed to be a teenager and was said to be 14 in the French translation. Juliana and Florian are supposed to be around the same age as him and Penny is close in age to the MC).

Nemona: 15-16 years old (older than the MC but not by too much).

Arven and Carmine: 16-17 years old (I think theyd both be the oldest out of the rivals but Arven is a bit older than Carmine imo).

Harmony, Paxton, Urbain, Taunie, Lida, and Naveen: 16-17 years old (they seem to be old enough to be legally emancipated but they're referred to as​ children by Jett).

Ansha: 4-6 years old (imo she was either born a few months after the events of XY or she was a baby during that time and we just didnt hear about her).

Korinna: 19-21 years old (she was most likely a teenager during the events of XY, imo between 14-16, and it has been five years since then).
