You know this page may include offscreen reversions, which are scenes of characters transforming occur offscreen, such as in the case of My Little Pony: The Movie.
In Ben 10, some of Ben's transformations into aliens occur offscreen.
There is also one scene in My Favorite Martian, when Lizzie uses the nerplex gum, her transformation is offscreen.
I also added The Garfield Show with the episode Prehistoric Pup, as Odie transforming into a giant prehistoric dog happens offscreen.
I also altered the offscreen transformations from the Transformers films, is that in the first film, in addition to Bumblebee, there is also a scene where the Autobots arrive on Earth, a truck drives between Optimus Prime and the camera, and when it leaves the frame, he has scanned and transformed into a copy of it.
In the Ultimate Spider-Man episode "The Savage Spider-Man" after Ka-Zar used a skunk-like creature as medicine on Spider-Man when he turned into a Man-Spider, the scene of him turning back to normal was not shown and in the Dexter's Laboratory episode "The Big Sister", when Mom eats the experimental cookies Dexter left out, her giant alien transformation occurs offscreen. So can these be on this page? I added two of these on it.
There is also one in Marvel's Spider-Man, when John Jameson experiments with the lunar crystal, it turns him into the Man-Wolf, but the transformation is offscreen.
