>>55508398Wrong.
- Red is stated to be 11 in the manual for the Gen I games
- Brendan/May are stated to be 12 in ORAS, while Wally is stated to be 10
- Elio/Selene and Hau are stated to be 11, Gladion is Lillie's older brother so either he's 12 or she's 10
- Calem/Serena are said to be older than Emma whose age is 16, so they're presumably 17
- Hilbert/Hilda were envisioned to be around 16 when they were made, but it became 14 later, and Nate/Rosa are presumably similar
- Lucas/Dawn in PLA are said to look about 15
- Ethan/Lyra are taller and weigh more than Lucas/Dawn in Gen IV, so they are presumably around a year older
And here is the game timeline:
The plot of Pokémon Ruby and Sapphire and Pokémon Red and Green are contemporaneous. They are then followed by the equally contemporaneous plot of Pokémon Gold, Silver, and Crystal and Pokémon Diamond, Pearl, and Platinum, which are set three years later. Pokémon Black and White are set an unspecified amount of time after those games. Pokémon Black 2 and White 2 are set two years after those games, and are contemporaneous with Pokémon X and Y. Pokémon Sun and Moon and Pokémon Ultra Sun and Ultra Moon take place two years after the events of Pokémon Black 2 and White 2 and at least 10 years after the events of Pokémon Emerald. Pokémon Sword and Shield are known to take place after the events of Pokémon Sun, Moon, Ultra Sun and Ultra Moon because the Pokémon Sword and Shield Pokédex states that research notes of Type: Null were stolen leading to creating more of these Pokémon, in contrast to the three that existed in the previous games.
Therefore, a minimum of 10 years and a maximum of 20 years elapse between RGB and SMUSUM. So Red is between 21 and 31 years old in SMUSUM.
RGBY/RSE/LGPE > 3 years > GSC/DPPT > at least 3 years > BW > 2 years > B2W2/XY > 2 years > SMUSUM > ? years > SWSH
