I found Movie storyboards
From The Lost Media Wiki
Cordial greetings, umm... I found some storyboards of the movie... I know there was a version where Dex was human, but I don't know what happened... I thought because the movie was so infamous no one would put it on one of their animation reels (Apparently, who knows). So I decided to look the full cast and crew on Imdb, and i look for some storyboards and I found these, I don't know where I should keep them, so I'm leaving them here for you to see... There are some cartoonish expressions in there... Storyboards: https://garykclair.wixsite.com/mysite/copy-of-justice-league-alien-invasi I hope I have helped, cordial greetings :).
