Trivia

• The rules of evolution seem to be very different in Pocket Monsters manga. When Green's Charmander first evolved into Charizard temporarily, it omitted the Charmeleon form. Later, it evolved off-screen permanently and it's unknown if he ever was a Charmeleon. It is possible that he was able to omit the Charmeleon form again.
