Welcome to Kryptonian.info
This website was once only home to Darren Doyle’s (my) unofficial Kryptonian language project — started in 2003 with inspiration from Smallville. Fast forward to today, and my Kryptonian has been used on Supergirl and Superman and Lois … which I guess makes it not so unofficial anymore. The site has now expanded to include information on all the depictions of the Kryptonian languages over the years.
If you’re wondering where to start, I recommend the History page which gives a detailed timeline of the depiction of the Kryptonian language through the ages.
