I don't actually know the characters names but you'll still get the idea.
Rule 63 Soarin: Hynden Walch...Princess Bubblegum (Adventure Time)
Rule 63 Fleetfoot: Justin Roiland
Rule 63 Spitfire: Christin Slater

Again that's all I got so far.

I never would've considered Christian Slater as a r63 Spitfire, but it works disturbingly well.

PRINCESS BUBBLEGUM = PAIGE MOSS

Justin Roiland from Rick and Morty

ChristinSlater do you mean Christian Slater

6270460
Not Paige Moss, I'm talking about the one who plays Bubblegum in the current seasons of Adventure Time and Starfire in Teen Titans

And sorry if I misspelled Slater's name.
