Don't Be Fooled By Her Size. This 9-Year-Old Girl Is A Full-On Fighting Machine.

Just skip to the 1:37 mark in the video. Believe you me.

Don't be fooled by Jesse Jane McParland pint-size stature. The 9-year-old from Ireland is a full-on fighting machine, and there's no stopping her when she's got a sword in her hand. Just watch the video above to see her kick butt at the 2014 Junior World Association Kickboxing Organizations (WAKO) World Championships. 

But it wasn't until this year that McParland started to gain international recognition after auditioning for Britain's Got Talent. In that episode, McParland mentions that her parents initially wanted her to be an Irish dancer, but instead she opted to practice martial arts. She's been practicing for six years now, having started when she was just 3 years old. 

Yup, you probably wouldn't want to cross paths with this little girl when she's mad.
