The max limit for this team is 7, and when it's full there will be a separate team, but for Samurai.
The Green Ninja
Matthew Garmadon is the leader of the group, the ninja of Energy which is basically all the elements he can control, and the usual quiet and serious one. He was appointed leader by Sensei Wu, seeing as if he was fit, just like his father. He is the main engineer of the group aswell, making mechs,machines,bombs,etc. His father is Lloyd Garmadon the Elemental Master of Energy, and his mother is Ari Hence (OC), the cousin of Cole Hence who also had earth powers but couldn't control them, therefore making him also related to the old Earth Ninja. He can sometimes be a little mean to the group, not counting Availia since she is the closest with him. Once you get to know him he is actually a very nice boy. He is currently close to becoming a full Elemental Master, since he has trained with his great uncle for 9 years.

The Red NinjaAvailia, or mostly known as Ava is one of the few members of the group who was the first to be recruited. She is the ninja of Fire, as her father is Kai, The Elemental Master of Fire. She usually is the one to rise to irritation and anger quicker than the rest, and doesn't fully think things through before speaking or doing something. But, there is an a amusing and childish side to her that reveals itself when she is comfortable and with the people she loves.

Annora, who has the rare ability to control two elements, lightning and water, hardly ever takes anything seriously, but can almost always make someone smile with her sense of humor. Though she isn't extremely intelligent, she isn't stupid, either, and though she is highly observant, it sometimes takes her a while to catch on to things. Annora will also either flat-out ignore or not pay attention to instructions, or if she doesn't like what she is told, will do her own thing. She works better in a group than alone, however, and will always stay close to her friends.
