Kai! Short tempered yet good natured!

Fittingly for his elemental affinity, Kai is very hotheaded, prone to taking action before he thinks things through. His single-mindedness made interaction with his teammates difficult at first (especially due to his worry about Nya), but he eventually learned to work with the other ninja.  

Get ready because Kai has an even bigger challenge ahead of him when taking on Shadowy and Retrieving the Ancient sword of the Ancestors in NINJAGO! MYSTERY OF THE SWORD!
