Answer 2

The best answer is "a wolf in sheep's clothing" given by facebook, but this one conveys the message as well. It can be used with non-humans too.

devil in disguise

Something or someone that appears to be good, useful, or benevolent, but that in reality proves to be the opposite:

When I first met my ex husband, I thought he was the nicest, most generous man alive, but he turned out to be the devil in disguise.

The new cancer treating drug held great promise, but it proved a devil in disguise when the true scale of its side effects became known.
