To sum up the general theme of this: turning into a giant snake never helps, turning into a dragon can at least make for an epic final battle - though it's not as if villains tend to win otherwise anyway - and turning into a regular/small snake is a stroke of genius that often tends to allow for a quick getaway or a sneak attack.

The Maleficent example from Sleeping Beauty is mentioned twice on this page: once in "never works" under western animation and once in "partially works" under film. Which do people think it should be in?

Suggested alternate titles: A snake am I; A Dragon am I.
