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. I recommend starting with the History page for a comprehensive rundown of the evolution of Kryptonian.
