Suicide Squad is one of this summer's hottest movies. The movie reaching 146.8 million dollars at the box office. One of the most famous characters from this movie is the crazy Harley Quinn. But, what has made her so popular lately?

1. She is beautiful.

Margot Robbie was the perfect actress to play her. She is hot. Although she is Australian, she has a perfect Brooklyn accent to match Harley Quinn's background. Margot also looks great in Harley's skimpy costume.

2. Her craziness.

In the movie she is known for being psycho and crazy. I think that's why people love her so much. She would be boring if she didn't act so crazy. Her actions and comments add to the movie!

3. Her attitude.

Harley has a carefree attitude all throughout the movie. She's a bad a**. She takes things into her own hands. She clearly does not give a f**k about anything but her puddin'.

4. Her Love.

She clearly only loves her Puddin' (aka the Joker) and would do anything for him. She's got such a strong love for him. It makes her sweet, caring and human. They have one insane relationship and I admire her for putting up with it. She clearly has a lot of love for him and only him.

5. Her costume.

Let's face it, she looked hot while kickin' butt. Her costume showed off everything. It showed her perfect body. It's also a pretty easy costume to make at home. So clearly, that will be this years top Halloween costume for teenage girls this year.
