Debunking BOTW Link’s age:
UPDATE EDIT - Link being an adult is suggested in Age of Imprisonment:
This coincides with my old debunk post below:
In botw, only Zelda is confirmed to be 17, when she’s finally allowed to visit the Spring of Wisdom on her 17th birthday. It’s an assumption Link is the same age, not canon. If he’s able to accompany her, he can be older.
NOTE: wikis can be editted by anyone without evidence. So I won’t be taking the loz wiki saying he’s 17 into consideration as there’s nothing concrete to confirm that.
1) Creating a Champion suggests he could be an adult. This is a book made with the botw dev team. Below are page snippets from pg 107 & 377.
2) Drinking Age: Noble Pursuit
Japan’s drinking age remains at 20. It’s likely Nintendo follows their own country’s law in regards to drinking. Link could be considered an adult unable to drink yet.
3) Link says I’m over 100, not 117.
Also Link is a short king, most likely mistaken to be much younger and not taken seriously by other npcs.
This entry doesn’t suggest they’re the exact same age. It can be said for both teens and young adults. Older gen like Urbosa and Daruk (Urbosa was Zelda’s mum’s friend) would say this to anyone younger than them.
Conclusion: If you see him as 17, you do you! Based on the info above, it’s valid to consider him an adult. As of Tears of The Kingdom, he definitely is one!
