One of the coolest things about the Archie Comics Teenage Mutant Ninja Turtles comic book is the turtles' future selves. Due to some shenanigans, the Donatello & Raphael of the future had to travel back to the early 90s to bring their past selves into the future. I think it had to do with a time-traveling shark dude. Don wore a funky trench coat full of gadgets and no mask.

This is Donatello opening some sort of portal to where & when, I know not. But, it's seems to inhabit monarch butterflies. I dunno how Foof got in there. I tried to make the opening in space & time look like it did in the comic books, hence the big, black, blotchy stuff.
