Freak the freak out like scene in anime

[DarkAngel]

is there such an anime moment where the ugly duckling is just the disguise of a beautiful anime protagonist?
i haven't seen anything like that so far lol

It's hard to say.
There are similar situations where protagonists are in disguise but not in this way
