4. Aquarius
An Aquarius is likely to come across as one of the nicest and friendliest people you’ll ever meet and they have little or no tolerance for those who are unkind to others. With a tendency towards the rebellious, an Aquarius won’t hesitate to act if they feel that they are being mistreated by others. Those who make the mistake of messing with them are very likely to get a little taste of their own medicine in return.
